Ice Halos over Bavaria

What’s inflicting those irregular sky arcs? Ice crystals. Whereas crossing a self-discipline of original snow stop to Füssen, Bavaria, Germany, earlier this month, the photographer seen that he had entered an ice fog. For suspended water to freeze into an ice fog requires pretty cool temperatures, and indeed the air temperature on for the time being changed into as soon as measured at smartly beneath zero. The ice fog mirrored mild from the Solar surroundings in the support of St. Coleman Church. The pinnacle result changed into as soon as one of potentially the most attention-grabbing spectacles the photographer has ever considered. First, the spots in the featured characterize are no longer background stars but suspended ice and snow. Next, two prominent ice halos are considered: the 22-level halo and the 46-level halo. A few arcs are also considered, including, from top to bottom, antisolar (subsun), circumzenithal, Parry, tangent, and parhelic (horizontal). At closing, the balloon shaped curve connecting the end arc to the Solar is the rarest of all: it’s miles the heliac arc, created by reflection from the perimeters of hexagonally shaped ice crystals suspended in a horizontal orientation.
