A late November Saturday sky with waxing Gibbous moon, 86% of full. What does Gibbous mean, you say? Courtesy of Carpe Caelum:
The waxing gibbous Moon is very nearly full and illuminated generally from the right. This phase of the Moon is seen to rise sometime in the afternoon when few people are looking at the sky. This is why it usually goes unnoticed until it gets dark at sunset. By that time the gibbous Moon is well above the southeastern horizon. The Moon is in this phase for nearly a week between first quarter and full. Just a day or so before Full Moon the waxing gibbous Moon appears nearly full and might be mistaken for a full Moon. The Moon in this phase sets just shortly before sunrise.
