I am not sure what the reason for this light show since I can't find any reference material citing the light beaming phenomenon. I suspect it has something to do with refractive light reflection between the celestial objects. I was only able to snap one photo. Cloud cover came in and a snow squall followed on that 15 degree night. I waited to see if any light banding would show up after the full eclipse, but it didn't. I have never seen this phenomenon during any other lunar eclipse. If someone out there could give me a scientific reason for the lunar eclipse causing a vertical light beaming around the horizon, I would like to hear about it.
One thing is for sure, the light show was one of the most beautiful things I had ever experienced.
Here are some other photos from that night, including a not so good photo of the light beam I saw in the eastern sky (jet contrail also seen, and the moon for reference).
