Last of the Super-High Moons

I took this photo of the moon and Mars on Christmas Eve, just around 11:00 PM. According to the Old Farmer's Almanac, this was the last super-high full moon, until the year 2025.

The term "super-high" refers to the moon's arc (transit, path across the sky, etc) being much higher above the celestial equator than usual. The moon enters these super-high orbital planes about every 18 years, and, most recently, has been doing so since 2005. With this final full moon of 2007, the moon is now starting to descend to lower declinations.
