On 10 January 2009, Jan Smejkal observed a complex display in Prichovice, in which some rarer halo forms – such as the anthelion brightened by crossing Tricker arcs – were in action, too. The more frequent halo arcs included suncave…

The photo on the right, and another one ( 1 ) were taken on an airplane from Beijing to Singapore on 3 January. The Bottlinger Rings appeared two times in total, when the plane flew above patches of dissipating AC…

On 17 January, I (Matej Grek) went to Malenovice near Lysa hora in the Beskydy mountains to “hunt” halos in diamond dust, because humidity was near 98% and temperature below zero. However, as the temperature was still not low enough,…

The display developed soon after the snow guns were started at 21:30 and began vanishing no earlier than 05 in the morning when Ac clouds rolled over. It was an unusually stable display, the swarm stayed in the same location…

The new year started with two nice diamond dust displays on 3 and 7 January. The weather situation was similar: above the Inn valley there was a low stratus layer with an upper limit of ca. 1000-1200m. The passable Sudelfeld…

In the image above the two photos in rigth hand column represent intense pillarforests with superparhelia rising from nearby lamps. The sight is very impressive as tens of lamps around the observer create pillars. Furthermore, one can see a long…

Sub-Kern, although already documented by Riikonen ( 1 ), was in the back of my mind when the plate crystal swarm got better in the night between 1st and 2nd January 2008. I was forced to photograph in a light-polluted…

Reflected Lowitz arcs were seen for a short period of time in Hyvinkää, Finland, on the very first day of the year. I used the spotlight as a light source. In the beginning of the night fierce pillars formed above…

During the night of 2-3 January 2008 subhorizontal plate halos were observed in Tampere, Finland. The Sub-Kern arc and circumnadiral arc (both first discovered by Marko Riikonen in Rovaniemi in December 2008) are the most noteworthy forms in the display.…

During the night of 1-2 January 2008 bright divergent light halos were present in Tampere, Finland. Most notably, bright, colored superparhelia were observed. The colors are readily visible in a bigger image ( 1 ). Crystals were sampled ( 2…
