Visibility III / V
I went out to photograph the repos with a guy on Tuesday night when the values were good, but then it started to cloud the top clouds to the scene. After a small downstorm, I was left waiting to see if there would be a sequel, and as I looked at the sky, I noticed a pale western cloud. I checked the camera to see what it looked like and what it looked like. The confusion was caused by the fact that it was almost north of that halo / side moon and moon in the southeast. Apparently it is a 120-degree side moon and part of a horizon ring as well. The images are unfortunately inaccurate, because when I was shooting the repos, I inadvertently snapped the focus, and at no point did I remember to check it out. Pictures taken from 21.38 to 21.52
