The NSS provides such a program for PCs to its local chapters.
Check out the NSS local chapter near you. I don't know exactly where
Stanford is in CA, but the local NSS chapters in California are:
Chico L5: (916) 877-4612 [Paradise]
Contra Costa/Alemeda L5: (415) 530-1971 [Oakland]
Exocalifornia L5: (408) 667-2413 [Big Sur]

Santa Cruz L5: (408) 425-7151 [Santa Cruz]
Silicon Valley L5: (408) 729-9555 [Santa Clara]
You shouldn't have to be an NSS member or a chapter member to get
the program, but if you're not you'll probably have to supply your own
disk.

The observing method, generally, was to observe as much of the sky as
possible from the end of nautical twilight (sun at -12) for about an
hour (1.5 hours in summer) with a concentration toward the zenith to
about +45 altitude in the east without looking for specific objects
during the observation period with identification afterwards.
Typ Max Magn - is the maximum visual magnitude the satellite under
best conditions for phase and minimum distance to observer.
(*) indicates that since the satellite was observed once, typical
max magnitude cannot be determined.
(#) since Hubble is in a 28.5 degree orbit it is always low on the
southern horizon from +39.6 latitude and would be brighter at
lower latitudes.
Max Vis Magn - is the maximum visual magnitude the satellite appeared
during any of its apparitions. It is typically a temporary sudden
increase to the magnitude indicated.
Number times obs'd - is a function of the satellites brightness and
its period of visibility which is a function of time in orbit (note
that the Shuttle has been observed once during the period) and
inclination which determines how long it remains in (and returns to)
the twilight window.
The question mark (?) after the satellite name indicates that the
identification of the object is preliminary.

The upper stage of the rocket used to launch COSMOS 2082 is currently
visible to observers of the mid latitudes of the Northern Hemisphere
during the early evening hours. COSMOS 2082, probably an electronic
intelligence satellite, was launched from Tyuratam on 1990 May 22.22
UT. The rocket body (NORAD No. 20625, int'l des 1990-046B) is in an
orbit of inclination 71 degrees, height above Earth of about 850 km,
with a period of 101.9 minutes. It is the last stage of the CIS ZENIT
(ZENITH) Type J or SL-16 intermediate payload launch system. What
remains in orbit is roughly a cylinder of diameter 3.9 meters and
length 10.4 meters. There are 6 such rocket bodies in similar orbits.
Due to subsequent problems this is the last ZENIT to be launched.
In July 1990, I observed COSMOS 2082 r/b varying in brightness with a
maximum of +2.5 magnitude. In September 1990 it appeared to be steady
in brightness; however the following November it varied with a period
of one second. In January of 1991 the period had lengthened to 1.2
seconds. Currently the period is 13 seconds. The previous 5 ZENITH
rocket bodies acted similarly. The variability is caused by the
tumbling of the cylinder. Eventually the long axis will point to
Earth and the variability will cease.

Earth Satellite Cosmos 1220 (NORAD #12054, COSPAR 1980-089A) was
launched from the (then) USSR from Tyuratam (Baikonur) on 1980 Nov 4
with a SL-11 (F-1-m) launch vehicle. This satellite is in an orbit
inclined to Earth's equator by 65.0 degrees. It makes one revolution
every 97.8 minutes and comes to within 552 km of Earth's surface and
is most distant at 751 km. Its brightness is similar to a sphere of
6.0m diameter.
Cosmos 1220 is thought to be an military electronic intelligence ocean
surveillance satellite. It is one of three similiar satellites. The
others are Cosmos 2096 and Cosmos 2122. In June of 1982 Cosmos 1220
exploded into 80 pieces. The elements below are for the largest
fragment. It is beginning a sequence of evening passes for North
American observers.
I have observed Cosmos 1220 from Denver once the last three summers at

I like to include observations of some of the brighter artificial
satellites, and also the astronomical satellites, in my astronomy
course student observing sessions. Predicting the apparition of these
little wonders helps heighten the participation of the many students
who cannot be at the eyepiece of a telescope at any given time. (Of
course I won't mention the time that COBE went flashing right through
my zenith and I couldn't tell them what it was, even though I had to
talk about it in my lecture the very next day!)
The ones Steve South saw are my favorite satellites, the NOSS
"constellation". My wife and I sometimes set an alarm clock and run
out into the back yard to observe them on good passes. Having good
binoculars, a clear sky (or at least sucker holes in the right
direction), and a knowledge of the sky all help in doing so. Other
desirable equipment are a radio tuned to WWV and a portable audio
casette recorder for your observations, especially timings.
After that, it is nice to know what it is one is looking at. Ted
Molczan, who runs a bulletin board in Toronto, provides a valuable
service to amateurs who observe or even use satellites. Below I quote
information on the NOSS satellites received by Ted from unidentified
sources and posted to his board. I can not attest to its reliability,
and I pass it on in the spirit of sharing a rumor, though it is not in
any way implausible in my view. What follows is all quotation, but I
will omit the customary ">"s because I don't like them.

NOSS (Whitecloud) Satellites
----------------------------
One of the more interesting U.S. DoD programs is the secret NOSS
(Naval Ocean Surveillance Satellite), code named Whitecloud, which is
believed to use satellite borne radio interferometry to locate and
track ships at sea by their radio transmissions. NOSS satellites use
a 63.43 deg inclination, 1116 km altitude orbit.
First Generation NOSS
---------------------
The first NOSS launch, probably a technology development mission, was
71110A (5678). The first of eight operational first generation
launches was 76038A (8818); the most recent was 87043A (17997).
The NOSS constellation consists of three orbital planes, each
containing four satellites flying in formation; a main satellite and
three sub-satellites. Seen from the ground, the sub-satellites are
spaced only a few degrees apart.
The satellites are small and usually rather faint, about magnitude 7
or 8, however, they have been observed to frequently brighten
spontaneously to magnitude 2 to 4. One long time observer believes
that they periodically deploy solar sails to provide the propulsion
required to maintain their precise formation flight. One piece of
orbital evidence which may support his theory is that the satellites'
orbits become more eccentric with time. That is a well known
consequence of solar radiation pressure perturbations.
Second Generation NOSS
----------------------
A Titan 4 rocket, launched on 8 June 1990 from Florida, carried four
payloads into orbit, three of which were discovered by Russell Eberst
to belong to a new, apparently second generation, NOSS cluster. The
satellites are about two magnitudes brighter than older NOSS
satellites; also, there appears to be no fourth "main" NOSS satellite.
The new cluster, 90050B-D, is in the same orbit as the eighth first
generation cluster, 87043.
The orbit of the fourth Titan 4 payload, 90050A (20641) is unknown.
Originally, it was in a 61 deg inclination, 455 km altitude orbit, but
it manoeuvred on the night of 19-20 June 1990, and has not been seen since.
It probably deployed the NOSS cluster in its 63.43 deg inclination,
1116 km altitude orbit, before manoeuvring to its final orbit. There
has been some informed speculation by news reporters that 90050A is
mainly an imaging reconsat, and that the NOSS cluster was only a
secondary payload.

Earth Satellite USA-33 (NORAD #19625, COSPAR 1988-099A) was launched
from Vandenberg Air Force Base on 1988 Nov 6 with a Titan 34D launch
vehicle. This satellite is in an orbit inclined to the Earth's equator
by 97.9 degrees. It makes one revolution every 97.5 minutes and and
currently comes to within 267 km of the Earth's surface and is most
distant at 1006 km. It is roughly cylindrical with a 3.0 m diameter
and length of 15.0 m--similar in size and shape to the Hubble Space
Telescope. It is thought to be a Keyhole 11 optical surveillance
satellite and is designated KH 11-8 in Ted Molczan's list of 730+
two-line elements.
KH 11-8 is in what is called a "sun-synchronous" orbit. Such an
orbit's nodes (intersections of the orbit plane with the Earth's
equatorial plane) precess, due to the Earth's equatorial bulge, at the
same rate as the Earth's revolution about the Sun. This causes the
satellite to pass over a place on the Earth's surface at approximately
the same local time at that place (a favorable situation for an Earth
resources or surveillance mission). In this orbit it can be seen only
during the summer when the sun's rays shine over the pole. In the
north hemisphere we are now well into summer and KH 11-8 will be
visible for the next month or so. It can be seen around 10:20 pm +/-
50 min (your daylight savings time zone) traveling from SSE to NNW on
its way to the other side of the Earth where it is 10:20 am (or so)
local time.
Unlike KH11-8's older brother KH11-6, KH11-8 still has fuel for
maneuvering and changes its orbit frequently. The orbit change is a
repositioning of the orientation of the ellipse and a lowering of
perigee. Inclination changes little.
I have observed KH11-8 from Denver 12 times the last four summers
mainly at magnitude +2 with a variation of about 1 in visual magnitude
from pass to pass.

Here is an account of a sighting of one of the famous
NOSS/Whitecloud satellite clusters by Ron Dantowitz of the Hayden
Planetarium in Boston. Ron is new to satellite watching, though not
to astronomy in general, and I thought* his story of stalking,
observing and analyzing the triad would be of interest to
astronetters. This first appeared in the Compuserve astronomy forum,
and is reposted here with Ron's permission.
**********************************************************************
Hello Fellow Satellite Watchers!
For those of you who've been asking questions about the NOSS Triad sats,
here are some of my observations from pass # 614 over Boston, MA on
Monday 8 Nov, 93.
Triad rose in the North, but as I scanned w/ binocs, no luck. After
sats reached their Max elevation of 76 degrees, I was about to give up.
But then... Voila! I found them w/ my 7x50 binocs, as they were
entering the square of Pegasus. It would have been impossible if I
didn't have my notebook computer up on the roof w/ me, showing me the
pass on Traksat's "Star background" option. It's pretty neat to watch
the satellite creep across the computer-screen starfield, and look up to
see the sat gliding right by Alpheratz, poof! Like pulling a rabbit out
of a hat. But sorry, I have digressed... I'm too excited by the idea
of seeing 3 sats flying in formation!
Here are my observations, sans excitement :-|
My binocs were 7x50, with a field of 7.1 degrees diameter. I noticed
that the sats did not form an equilateral triangle, but something like
this: Facing southeast, when the triad was at approx 45 degrees
elevation (in the Square of Pegasus):
. 3
. 2
. 1
\direction
\ of
\ travel
Southeast +
The direction of travel was south, from #2 to #1. Whether this non-
equilateral triangle was due to perspective, or maybe they weren't in
perfect triangle... it all depends on the real 3-d arrangement of sats
in space.
I estimated the distance between the satellites #1 and #2 in two ways.
Method 1) Time
1. In my diagram above, #2 was following #1 almost dead behind. As #1
passed a bright star, I noticed it took 7+/- seconds for #2 to pass the
same star, as it followed #1 in it's orbit.
Assuming that the sats were cruising at about 17,500 mph in their orbit
(at altitude approx 700+ miles up) it's a simple calculation:
distance #2 to #1: d = (17,500 mph) x (1hr/3600sec) x (7 sec) = 34 miles
Assuming my timing was within 1 second:
dist = 29 miles (6 sec) to 39 miles(8 sec), with 34 being the average.
Method #2) Geometry
First off, I have more faith in the "timing" method, above. This next
method has more assumptions and guesstimations.
I noted that the angular separation between #1 and #2 was (approx) 3.5
degrees when I observed them at (approx) 45 degrees elevation.
#2 was following #1 EXACTLY, so that the 3.5 degree apparent separation
was getting smaller, as the sats began to set in the south.

Now, from geometry:
If the sats were OVERHEAD, the angular separation between 1 and 2 would
be (3.5 deg/sin45)= 4.95 degrees. If they were overhead, they would
also be 700 miles away. Sooooo, if "d" is the distance between the sats
in miles,
d = 700mi x (sin(4.95deg))
= 60 miles.
So, the first (more accurate) method gave approx 34 miles separation
between the spacecraft, and the second method gave approx 60 miles. Both
are within the same order of magnitude, so we're doing pretty well, I guess.
Does anyone know the actual sep between these two particular sats?
My personal guess: 36.88132 miles. There appeared to be more distance
between #3 and the others, but no estimate here.
You really do need binocs - at least if you're in a city. Bring a laptop
comp w/you outside, and learn to translate screen position from traksat
to the real sky. It takes a little practice.
The skies were clear but light-polluted here in Boston.
I estimate that the trio was magnitude 5.5 - 6.0, but definitely not
brighter than 5.5 when they were 45 degrees elevation, in the SE (in
the square of pegasus). At the time of observation, the sats were
approximately 1000 miles from my eyeballs (which were 0.0000316 miles apart!).
I hope that this lengthy discourse is of interest to some of you out
there. I had to freeze my parabolas off to see them!

P.S. I also captured Cosmos 0955 r rocket booster on video through
a Meade LX200. I used a real-time 0.5 lux CCD at prime
focus. Video is a bit jumpy, but ok. I wish the LX200
could track those automatically!
Anyone ever try this before?

This is very cool. I'm glad to hear I not the only one in the Boston
(Cambridge) area that sits on the roof (braving cold and light
pollution) with with a laptop tracking things at night. (I'm new to
this, so slowly rising planets and stars are as far as I have gotten.)
A few thoughts:
1) Where can I find Traksat? I've checked a few ftp sites w/out luck;
is it a commercial program? (I love Skyglobe and have spent many
hours with it learning how things move in the sky, and yes I paid my
$20, well worth it.) I'd like not to have to rely on my 4-year old
daughter finding satellites for me watch (no she doesn't go on the roof).
2) We've built a high-performance camera pointing device for a small
CCD-camera in our lab (for use in tracking small objects for our robot
to catch). It seems this could be well used to aid visual tracking of
satellites and video taping them. If satellite positions can be
obtained in real-time from code running a laptop then this should be
possible (given a better camera and a bit of code to glue things together).
>> Anybody ever tried this?
(Yes, I know NASA and the military must do this all the time, but I'd
like to do it at on a high-tech roof-top budget). Since our system is
designed to detect and track moving objects, I can imagine leaving it
running overnite to track and tape all the moving stuff that crosses
its field of view (like satellites, planes, meteors, aliens...). Sure
would make for better morning TV viewing than the news or Sesame street
(but not shuttle launches).

Greetings,
Traksat is a shareware product, and is available off a number of BBS's.
Try T.S.Kelso's Celestial BBS at 513-427-0674, no parity, 8 data bits,
1 stop bit. If anyone knows of an ftp site for it or any of the popular
satellite tracking programs, I would be most interested as I am working
on an article on sat. tracking. Please post or e-mail directly.
There are a number of really good sat. programs out there. Here is a
brief list:
STSORBIT PLUS...........Dave Ransom author, obtain from Celestial BBS
TRAKSTAR................TS Kelso's program, ftp site:
archive.afit.af.mil pub/space
as well as the Celestial BBS
SEESAT..................Paul Hirose author, obtain from Celestial BBS
QUICKSAT................Mike McCants author, obtain from Celestial BBS
VIEWSAT.................Dave Rasmussen author, obtain from Celestial BBS
These are all IBM-DOS compatable.
As for the NOSS satellites, they must have rather large reflecting
surfaces of some sort. I tracked them once through 10x50 binoculars
and estimated their mag. at probably 5th or 6th when they were nearly
overhead at azimuth of approx. 70 deg. However, as they moved further
away from me and dropped considerably in azimuth I was able to spot
them at about 20 - 25 deg. above the horizon. Their phase of
illumination must of been near 100 percent, because even at that
azimuth, and at a much greater line of sight distance they were easy
3rd magnitude objects. Anyone know a little more about them?

Subject: More about NOSS/White Cloud
Date: 11 Nov 93 17:52:37 PST
Organization: Science Applications Int'l Corp./San Diego
The Russian journal "Foreign Military Review" recently published a
four-page article* on the history, characteristics, and orbitology of
the NOSS/White Cloud satellites. These, of course, are the satellites
which fly in formations of three, to the delight and frequent surprise
of sky-watchers.
Two tables from the article are given below. To (hopefully)
forestall some confusion, here is what the author says about the NOSS
and SSU components mentioned in Table 2:
"In 1976-1980 the Pentagon deployed on orbit an ELINT system
consisting of three groups of first-generation SSU satellites. The
satellites, mounted on a NOSS satellite-platform with a multiple-
start liquid engine, were launched from the Western Test Range on
an Atlas booster into circular orbits at an altitude of 1100 km
and inclination of 63.5 degrees. Forming the orbital layout
[Formirovaniye orbital'nogo postroyeniya] of the group was carried
out in the process of multi-impulse maneuvering of the satellite-
platform and sequential seperation from it of the three small SSU
satellites." (An "impulse" in this context is the same as a "burn"
in U.S. space-speak.)

Subj: Strange Observation
The message below was received from Erik Hoeg of Copenhagen University
Observatory. Anyone with a possible explanation about the observations
is invited to contact Erik Hoeg (address at the end of the message).
Relayed by Ton Schoenmaker - Kapteyn Observatory - The Netherlands

Message #7 on `Tygorm', 16 Nov. 1993:
#7 is an update of #6. It contains a table of observations;
a correction of total observation time from 85 to 70 minutes;
a new observation; more details, and a rearrangement of sections.

A mysterious -9 mag object
==========================
The object `Tygorm'
------------------
An object near zenith was discovered and observed by the weatherman A
on the Danish gas production platform Tyra-East in the North Sea at
position 55 deg 43.5 m north, 04 deg 48.2 m east. The observation
was taken between 3:50 and 5:00 UTC on 20 Oct 1993 and was reported
to the present author from 7:00 UTC the same morning and in numerous
phone conversations since then. Its integrated brightness was
about -9 mag.
I would be grateful for your assistance.
It should have been seen from elsewhere since the night was quite
clear and observers within a radius of 1000 km would have seen an
object brighter than -6 mag at a zenithdistance of less than 80 degrees.
Observer A
------------
An object near zenith was discovered and observed by the weatherman A
on the Danish gas production platform Tyra-East in the North Sea at
position 55 deg 43.5 m north, 04 deg 48.2 m east. The observation
was taken between 3:50 and 5:00 UTC on 20 Oct 1993 and was reported
to the present author from 7:00 UTC the same morning and in numerous
phone conversations since then. Its integrated brightness was
about -9 mag. The moon was below the horizon.
The object was watched by observer A every 15 minutes for 70 minutes,
interrupted by clouds as he looked out at 5:15. He saw a diffuse
circular orange disk of the moon's diameter without structure, but
he was much disturbed by background light from a big gas flame on
the platform. The observer used naked eye and a good binocular. He
noticed a grainy surface. He saw no change of brightness or
appearance during that time.
The object stayed for observer A at nearly constant distance to
Capella which was seen at 10 degrees to WSW at 3:50 UT and at
about 7 degrees at 5:00, the times of first and last sight.
This indicates a westward motion among the stars of 3 degrees
in 70 minutes, although this figure is uncertain and could be zero.
Derived positions are given in the Table.
----------------------------------------------------------------------
Table 1. `Tygorm' was discovered by Observer A in the south-east
North Sea at 3:50 UTC on 20 October 1993. It was then 5.7 deg south
of zenith and 1.0 deg east of the meridian.

Time Tygorm sun earth
UTC RA 1950 Dec h_sun H_shadow
3:50 6h 10m 50.0deg -21.8deg 490km
5:00 5h 52m 48.8deg -12.0deg 142km
----------------------------------------------------------------------
The constant appearance and the celestial motion indicated an
astronomical object, perhaps a comet. But a report to B. Marsden on the
same morning did not bring any further observation, and it was
concluded that the object must be local. This hypothesis has however
led to no acceptable explanation of the phenomenon.
The surface brightness was estimated by a simple visual photometer to
one percent of the moon. The photometry was obtained by A five
days later on my proposal by watching the first quarter moon through
the two acryl plates of an empty tape cassette. He estimated that
the object was considerable brighter than the twice reflected
image of the moon. Since this image has a surface brightness
about 0.3 percent of the moon, the object has had a surface brightness
about one percent of the moon. Since the integrated brightness of
the full moon is -13 mag and the total area of the object
was at least one square degree as seen by the other observers a
total integrated brightness about -9 mag is inferred.
Since the reflectivity of the moon is about 0.1 it follows that the
reflectivity of the object is 0.001, if it is shining in reflected
sunlight. But this does not agree well with observer B's statement
on orange and bluish colour, indicating a self luminous plasma.
Observer B
----------
A ship 500 m south of Tyra was called by radio and the object was
observed by observer B four or five times during about 60 minutes.
He tried to photograph it but gave up because of the ship's motion.
He watched the object directly and by means of a good binocular.
He could see much structure which did not change during the time.
It looked like a drop pushing a slim bow wave in front of its broad end.
A sketch of 9 November has been provided. He saw a granular surface,
with a large number of small points inside the object. The borders of
the drop were quite sharp, like a gas flame. It was orange in the
middle and bluish outward. He is sure there was only one drop.
Observers C and D
-----------------
The object was also observed by two persons, C and D, on the platform
Gorm, 18 km south of Tyra who had overheard the radio conversation
between A and B. They saw two orange drops close together, near zenith,
both drops being about one square degree. From their (independent)
sketches of 24 October and from phone conversations the declination
48.0 deg and the same RA as above were derived. This corresponds to
a parallax of -2 degrees. Permitting very generously a total error
of 5 degrees, the maximum parallax is -2+5=3 deg, and the minimum
height therefore 340 km above sea level.
Observer E
----------
The object was observed by E from a ship located 100 m
east of Tyra. He went up to watch when he heard the observer B
speak with observer A. His observation deviates much from the others in
geometrical appearance, but is discussed in detail because of
the unknown nature of the object, and because he might possibly
have seen it disappear shortly after 5:00.
He said he saw 3 stripes about "7 degres north of zenith". They were
equally long and looked similar to railway sleepers, about 8 degrees
long. Each one was in the proportions 3 m long, 30 cm wide and 20 cm
high, looking 3-dimensional. They were 1 meter apart; pink in colour
and perhaps transparent. He watched the phenomenon briefly several
times during about 15 minutes, starting about 4:00 UTC. He saw no
change during that period. About 5:05 he looked again, but it had
disappeared, although he thinks it was still clear sky. He also
saw stars but did not notice any in particular. His surroundings
were quite bright from the big gas flame, but he saw the phenomenon
very clearly. He has never seen anything similar.
His sketch of 9 November shows three bars placed besides of a moon in
order to show the relative size. This would make the bars two degrees
long, similar to that seen by the other observers, but much less than
the 8 degrees he mentioned first. When asked to try with fingers towards
the sky he finally decides that the length of the bars was 2
fingerwidths, or 4 degrees. He does not recall whether he wore glasses
on the morning, but he does not think it would have made any
difference. He is slightly short-sighted and wears -1 diopter. - I am
convinced he saw the same object as all others although it appeared so
different to his eyes.
Motion and height
-----------------
Since the slow motion and the great height are crucial for any
explanation of the object I discuss these questions more deeply.
The observed angular velocity relative to the rotating earth is about
12.5 deg/hour =6.E-5 rad/s (15cos(delta) for Capella + 3 deg in 1 hour.)
This implies a horizontal velocity of 30 m/s at a height of 500 km.
The very slow motion relative to stars is beyond doubt from
observation by A. Every 15 minutes he saw in fact both star and object,
and he made sure the next night that the star was really Capella.
The resulting declination of 50 degrees cannot have an error larger
than one degree.
An object must be less than 10 or 15 degrees within zenith in order
that people would say it is right at zenith. The sketch by D on Gorm,
18 km south of A, shows a star. D assures that it was very bright
and about 10 degrees from the object and towards west, as shown.
It must be Capella as D indicates, and there is no other bright star to
the north with which it could be confused. This excludes the
suspicion that the object could be far north of zenith due to a large
parallax. The declination of 48 degrees seen from Gorm is then
derived from the sketch by D. The resulting parallax is -2 degrees,
and the error is probably less than 3 degrees, but cannot possibly
be larger than 5 degrees, resulting in a maximum parallax of
-2+5=3 degrees. The minimum height is therefore 340 km above sea level.
The sketch by C contains a star said to be 3 times fainter than Polaris
which would make it 3 mag. It cannot be identified since there is no
star in the sky of similar magnitude, consistent with the position
derived from observer D. Observer C was not quite sure he put the
star at the right place in his sketch.
Any object should change appearance when it changes from being in the
earth shadow to become sunlit. The observed constant brightness during
70 minutes therefore precludes an object in the interval of height from
142 to 490 km since the earth shadow varied in this range. This
strongly indicates a height of the object above 490 km to begin with.
No explanation found
--------------------
Explanations in terms of noctilucent clouds, chemical experimental
clouds or space craft exhaust are not consistent with the long duration
of constant appearance and the nearly constant position relative to the
stars. Aurora seems to be excluded for the same reason and because
their was no special event on 20 October. P. Suesmann, Deutsche Telekom,
reports: "The sun was quiet with no flares or other events,
the geomagnetic field was unsettled and from the view of HF
propagation there was nothing extraordinary as well."
For dynamical reasons a distance larger than some 100000 km
seems required to explain the slow angular motion when we are
sure the height is larger than a few hundred km. Could an object perhaps
escape observation from other places of the earth if it had
a short duration of a few hours, combined with cloudy weather?
Could it be the (sunlit) exhaust of a distant spacecraft during orbit
control? But the linear size of a one degree object at such distance
is incredible, several thousand kilometers.
I intend to arrange a discussion between observers, geophysicists,
space scientists and astronomers.

For those interested in following the details of satellite orbital
behavior, the following information may be useful.
Over the years, several countries have launched spherical
satellites, initially for space surveillance system calibration and
later as geodetic aids. All of them, particularly those in lower
orbits, should be good for monitoring fluctuations in atmospheric
density and for 'normalizing' the behavior of other objects at similar
altitudes. (My particular interest is in using them as an adjunct in
studying the strange behavior of Cosmos 1697, Cosmos 1833, and other
objects of the Cosmos 1603 class.)
Lt.Col. Dr. Prof. (I can't resist listing all those titles :-) ) Tom
Kelso, sysop of the Celestial BBS and poster of orbital elements in
sci.space.news, has very kindly obtained extensive (basically all sets
since 1980) collections of orbital elements for a number of the earlier
spherical satellites and has posted then in file area 2 of his board:
look for the files with the form SAT0nnnn.2LE and a date of 5 Dec 1993.
The number of the BBS is 513-427-0674 until 6 January 1994 and 513-253-
9767 thereafter.
Below is a table of the information I've found on the satellites,
giving their masses and diameters; note that different sources give
slightly different values for these numbers, so don't do anything with
them that requires great precision. Additions and corrections are
welcome. For orientation purposes, there are also recentish orbital
elements for the objects.
