The Sky This Week, 2011 January 18 – 25 — Naval Oceanography Portal

The Moon brightens the late night and early morning skies this week, with Full Moon occurring on the 19th at 4:21 pm Eastern Standard Time. The year’s first Full Moon is popularly known as the Moon After Yule or the Old Moon in traditional sky lore. Like the Full Moon in December it occurs at a high northerly declination and because of this often appears particularly bright.
