At 13.03.2006 accumulate a diamond dust on the 1835m high top of the German mount Wendelstein above a 1400m high cloud layer, which consists of tiny little snowstars and very long ice columns.Therein forms out a bright glittering lower sun pillar with subsun. After a half an hour both halo kinds weaken clearly, but in return there accumulate two elliptical rings around the sun, before the whole halo spook was disappeared. The diamond dust was in the air all over the day, but no halos were observably anymore.
Unfortunately I don't remember that one.
