The day before it was cloudy and it was snowing a little bit, during the following night there weren’t any clouds and in the morning there was „normal“ fog. The minimum temperature in the night was about
5 °C below zero.
I don’t know when the halo display began, because when I reached this region full of ice crystals it existed already. And it still existed when I left the region (10:00 a.m). I took photos of it from about 9:25 until 10:00 a.m (CET).
You can see well the 22° halo, sun dogs, supralateral arc, the upper tangent arc, circumzenithal arc, tape arc, infralateral arc and last but not least the Moilanen’s arc. All phenomenas were seen all the time I was there. ( 1 - 2 - 3 )
