Visibility III / V
I went to the yard from February 15-21 before ten to see if there was a clear sky. I also saw a greenish sky behind the trees. I was in the nearby swamp a little before 11pm and not for a while when the repos started lapping 180 degrees wide. There were colors, red and purple, vertical rays and an arc and twist. No corona formed. I have realized that on that evening the northern lights would have been visible here earlier in the evening, ie they turned on and went out / went down more often. I was frozen, so I don’t know if they went on after I left.
