maybe your friend was resting on his right side when he made
the observation?

| on Kauai in mid-October moon was observed similar to Bali report.

| If I'm not mistaken, the only explanation for this would be a lunar
eclipse, but it would certainly be only a temporary phenomenon.

If I'm not mistaken, the terminator on the moon (the line between light
and dark) will run north and south (well, off 23 degrees or so,
but...). If you were on the equator, and saw the moon rising in the
east, wouldn't the terminator be horizontal?

I have lived in the mid latitudes (45% +-15) for all my life and
watched the earth's shadow on moon go from nearly vertical to nearly
horizontal. There was an old wives tale that said it wouln't rain
when the moon was holding water. (The earth's shadow nearly
horizontal.) I think what we have here is poor powers of obervation
rather than a new phenomina. %^)}

That is the moon's shadow on the moon unless you're watching during
an eclipse of the moon.

| 1025.7 | All a matter of geometry | CECV03::WARDROP | | Thu Nov 17 1988 18:45 | 14 |
| The bright side of the moon always "points" to the sun. (Obvious
if you think about it) The moon's orbit is roughly around the equator
so the moon tends to follow or lead the sun depending on phase.
The net effect is if you are in the tropics at the time of year
that the sun, and moon, are passing more or less overhead, the
terminator will be horizontal at moonrise and moonset. If you are
in northern climes in the winter, the sun and moon have a lower
trajectory and the terminator will appear inclined at moonrise and
moonset but will only be really vertical at its peak.
