This weekend, nights are lit by the waxing (increasing) gibbous (larger than half) moon, to be experienced as a sequence that culminates on Monday, February 25th, when the Full Snow Moon arrives at full phase at 3:26 p.m.
At that moment the side of the moon facing Earth will be fully lit because the moon will be opposite from the sun in its orbit around the Earth. Earth will be in the middle without blocking the sun’s light from reaching the moon: eclipses are infrequent because sun, earth and moon do not often precisely align.
The moment of full moon is different from its local rising time. Luna appears wholly round for about 24 hours, when it is rising and setting opposite the sun.
The Full Snow Moon rises on Monday, Feb. 25 at 5:51 p.m. in the east moments after sunset at 5:38 p.m. in the west-southwest. On the morning of Feb. 26, moonset in the west is at 6:33 a.m. opposite sunrise, which will be in the east-southeast at 6:34 a.m.
Nearly full moonlight shines during most of the 13 hours of darkness into the new week even though the waning (decreasing) gibbous moon rises close to an hour later each night.
February’s full Moon is traditionally called the Full Snow Moon because the heaviest snows fall in February.
Because hunting was difficult, some Native American tribes called this the Hunger Moon.
Other Native American tribes called this Moon the “Shoulder to Shoulder Around the Fire Moon” (Wishram Native Americans), the “No Snow in the Trails Moon” (Zuni Native Americans), and the “Bone Moon” (Cherokee Native Americans). The Bone Moon meant that there was so little food that people gnawed on bones and ate bone marrow soup.
