Visibility V / V
A great nocturnal halo show. One can only guess how wonderful it would have been if the full moon had been replaced by a bright Sun.
I noticed in the middle of the night that now a reasonably bright 22° ring can be seen around the Moon. I picked up a camera with a tripod and started to follow the development of the phenomenon. At first, nothing happened, and I used up the camera's battery by photographing just the tire. (I left those pictures out of here.) After about half an hour, the upper cloud started to become more favorable for the halo, and the lateral arcs started to emerge. After the arcs, the horizon ring also appeared. This best stage lasted roughly half an hour. After that, the upper cloudiness started to thicken and the halos slowly faded out of sight. 22° separated the remains of the tire even after the observation time recorded above.
The 22° ring was really bright for the Moon's halo at its best. The horizon ring was much dimmer. It was, however, a full circle for some time, but the optics of my camera are not enough to fit the whole circle in one picture. The fifth picture shows a horizon ring in the northern sky opposite the Moon. I also put USM-processed versions of the pictures here, where the halos stand out properly.
