22 degree halo

That circle around the sun this afternoon was a 22 degree halo, “a pretty common occurrence in the winter,” a meteorologist at the National Weather Service told MMM.

The phenomenon is caused by cold air above cirrus clouds, which the meteorologist said is happening today. The cold air creates hexagonal ice crystals.  The sun’s light reflects off the crystals, causing the effect many of us witnessed, uncommonly, today.

    Since this is a winter thing and if it occurs in spring then there can’t be “global warming” right ????

    The double “O” stands for Obama and Omnipotent…Abuse of Power is a pattern and practice of conduct since his election.

    But, how many of you noticed that in addition to the halo, there was a CIRCUMHORIZONTAL ARC about halfway between the horizon and the halo? It was not as bright as the halo, but was visible. I’ve seen plenty of halo before, but never as intense and long lasting as this one. Cool stuff that nature…
