Upper Lowitz Arcs - Geigelstein, Germany

The Geigelstein in the Bavarian Alps, Germany, offers a stunning view of atmospheric optics phenomena, including the Upper Lowitz Arcs. These arcs can be observed near the upper tangent and Parry arcs, as well as in proximity to the right-hand sundog. The presence of the Upper Lowitz Arcs adds an extra layer of intrigue to the already captivating display.

One possible explanation for the formation of the Upper Lowitz Arcs is the orientation of Lowitz plate crystals. When the HaloSim4 simulation is used with classically oriented Lowitz plate crystals, it shows relatively strong arcs close to the parhelia. This suggests that the display may have been created by Lowitz oriented columns with limited tilts of their long 'c' axes from horizontal. Interestingly, these crystals bear resemblance to Parry crystals with large tilts.

The Upper Lowitz Arcs at Geigelstein have been documented in various images captured by photographers. These images provide valuable visual evidence of this atmospheric phenomenon and help researchers better understand its characteristics. Claudia Hinz, for instance, captured a remarkable image of the Upper Lowitz Arcs at Geigelstein on October 15, 2005.

An upper Lowitz arc is apparent close to the upper tangent and Parry arcs and near to the right-hand sundog. Other images of the display also show the arc.

The HaloSim4 simuation using classically oriented Lowitz plate crystals shows relatively strong arcs near to the parhelia. It is possible that this is a case (Riikonen et.al.) where the display was made by Lowitz oriented columns with limited tilts of their long ''c' axes from horizontal. Such crystals are not dissimilar to Parry crystals with large tilts.
