Diamond dust displays in Sudelfeld Pass
On 3 January columns dominated. The 22° parhelia, the upper tangent arc with convex Parry arc and the colourful supra- and infralateral arcs appeared in –6°C ( 1 ).
The haloes on 7 January (see image above) were produced at a temperature of –8°C and consisted mainly of plates. The appearance of the phenomena changed at seconds intervals. We observed 22° halo with parhelia, upper and lower sun pillar, CZA, 46° halo, subsun, sub parhelia, parhelic circle with 120° parhelia and anthelion, heliac arc, Wegener's arc and Moilanen arc ( 2 ).
