Visibility IV / V
Petri Martikainen, Ursa (Itä-Suomi)
The evening was quite clear and the Moon shone bright in the sky, disturbing the observation of the comet. In the lands of Iltakymme, weak clouds began to gather around the Moon, and with the side eye, they could be seen as rings. I took a stack of a hundred pictures and checked the situation at the computer. Somewhat unexpectedly, the pictures revealed a fire, so I took the camera back to work. In the first stack of hundred pictures, there seems to be a 23° slaika and an 18° ring and parhelias in addition to the basic ring. In the latter set, in addition to the basic ring and the upper side ring, the 9° ring stands out. The other weak curves and rings visible in the pictures are probably artifacts from heavy handling.
After all, this was a nice surprise, because the snow season is already over in Hasamäki and we had to settle for admiring one another more beautiful ice fog halos from the watch. Even the upper clouds haven't really offered anything since the beginning of the year, when the sky has been solidly overcast almost the whole time.
