Here you see yesterday’s full supermoon moon with a wonderful lunar halo rising over Eggemoggin Reach at about 6 a.m. Such halos apparently are caused by the moon's reflected light bending out (“refracting”) through prism-like ice crystals in high-altitude cirrus clouds. Those clouds are somewhat visible in this longer shot:
The subsequent evening full moon rose into a clear sky and did not have a halo:
The December full moon is mostly called the Cold Moon. The name originated from Northeast Native American traditions of naming the full moon with a description of the season in which it rises. Among others, the Mohawk people called it the Cold Moon.
The Mohicans called this moon the Long Night Moon because it comes in the time of year when the winter solstice brings us the longest night and shortest day. The Western Abenaki people, in what is now western Maine and other parts of New England, called the December moon the Winter Maker Moon for obvious reasons.
