Wendelstein. In the morning I saw my first subsun in this year, which appeared in freezing fog. Later a veil of cirrostratus from a low pressure area over the Mediterranean Sea crossed the Alps from the south. Under those weather conditions, large halo displays can be seen very often.

So, in a meanwhile here are two more photos of the display three weeks back.When light source is at 0° elevation, some difficulties arises in identifying certain halos. Tricker arc and subanthelic arc merge together, as do helic and subhelic arcs.

I was photographing Ac len and iridescent Ac clouds, when I caught sight of the display. The elliptical halo formed on the ice crystal precipitation of one of the Ac.

Großglockner (3798m). The main ridge of the alps gave a warm welcome to us with a bright and diffuse fragment of the infralateral arc.

I trought that I could see upper tangent arc and inexpressive 22 degree halo. But the upper tangent arc was more and more brighter and lower tangent arc has not been seen. It crossed my mind that this phenomenon what i can see isn’t 22 degree tangent arc but 23 degree plate arc. I searched another pyramidal halos, but didn’t see it.

There were two particularly noteworthy displays this week. The first one was observed by László Henez "Felhőcske" on 16th September near Eger, Hungary. As a born halo-observer, even though he was quite unaware of what he was seeing, he took a picture of not only the sunward halos, but the anthelic side, as well, where about a Ágnes Kiricsihttp://www.blogger.com/profile/08611168432247808121noreply@blogger.com3tag:blogger.com,1999:blog-20777850.post-57076168900788533282007-09-18T13:40:00.000+00:002008-12-11T18:12:24.665+00:00Composite of the Kajaani display photosWith the diamond dust season soon on our doorteps, here is a tidbit from last winter.
