The moon's apparent size when it's near the horizon is an optical
illusion, but the moon's size does change a tiny bit due to the its
elliptical orbit.
Most visible during certain solar eclipses. If the moon is near apogee
during an eclipse it becomes becomes an annular eclipse instead of a total.
BTW, it looks like if the world doesn't come to an end in 2012, and we
manage to hang on until Aug 21, 2017 the contiguous USA will see it's
first total eclipse since 1979.
And it looks to be a good one with the path of totality stretching from
the western Pacific to nearly the Atlantic coast of Africa. In the US
the path of totality will cross Oregon, Idaho,Wyoming, Nebraska, Kansas,
Missouri, Kentucky, Tennessee, North Carolina and South Carolina, with
the greatest eclipse being just west of Hopkinsville, KY.
All of North America (Canada, USA & Mexico) will see at least a partial
eclipse, as will Central America and a good chunk of South America.

Cool. Hope I'm around to see it.

I've also read that it's just that the rising moon appears larger do
to it's relationship with known physical features near the horizon.
Color is generally more to the amber side do mainly to rising heat,
dust and moisture. Prior to that, I had wrongfully imagined that
moisture was responsible for slightly magnifying the moon's image.

18, 2011, 5:42 AM The moon is the same size no matter where it is
in the sky.? When it appears larger near the horizon, it's a
perceptual illusion.
