Halo display at South Pole on 4 February 1999

[gallery link="file" columns="5"]

Just scanned this one from my slides. It is basic South Pole summer season display. In the third and fouth image there is something at the horizon outside the 22° halo. Reflected Lowitz arcs or lower 24° parhelia? Hard to say which one, the clouds mask for example the possible lower 9° parhelia. Maybe there are both. The last heavily usmed image shows faint anthelion / diffuse arcs.
