This year will be the first full moon to occur on the winter
solstice, Dec. 22, commonly called the first day of winter. Since a
full moon on the winter solstice occurred in conjunction with a lunar
perigee (point in the moon's orbit that is closest to Earth)
The moon will appear about 14% larger than it does at apogee (the
point in it's elliptical orbit that is farthest from the Earth) since
the Earth is also several million miles closer to the sun at this
time of the year than in the summer, sunlight striking the moon is
about 7% stronger making it brighter.
Also, this will be the closest perigee of the Moon of the year since
the moon's orbit is constantly deforming. If the weather is clear and
there is a snow cover where you live, it is believed that even car
headlights will be superfluous.
On December 21st. 1866 the Lakota Sioux took advantage of this
combination of occurrences and staged a devastating retaliatory
ambush on soldiers in the Wyoming Territory.
In laymen's terms it will be a super bright full moon, much more than
the usual AND it hasn't happened this way for 133 years!
Our ancestors 133 years ago saw this. It will be 100 or so years from
now till our descendants will see this again.
