What's "up" depends on the viewing. Just after sunset, you are looking east
and one point, the point furthermost from the horizon seems "up". Just
before sunrise, you are looking west and again the point furthermost from
the horizon seems "up", but this is 180 degrees from the point that seemed
up in the early evening! At near midnight in the northern temperate
climates, you will be looking approximately south and a point about halfway
in between the other two "up's" will appear to be "up". In the southern
temperate climates near midnight, you will be looking approximately north
and a point about halfway in between the evening and morning "up's" will
appear to be "up", but 180 degrees from the view from the northern
hemisphere. Generally, the point closest to the horizon seems "down"
regardless of the moon's position in the sky.
I think.
