Odd radius rings from an airplane

Mónika Bodó photographed these odd radius halos on a flight from Amsterdam to Budapest on 20 June. The display lasted about 7-8 minutes and was observed during the descent to Budapest. Further photos are available in Mónika's album ( 1 ).

Odd radius display from the US

This photo of 18° and 23° rings and their arcs was shot by Michael Ellestad on 1 June 2009.

Short lived all sky display in Joensuu

This display was on when I woke up. It did not last long and was also plagued with lower clouds. I did not have mirror and could not see Wegener arcs, which are present in 3 minutes stack above.

Pyramid halos in Tampere, Finland

This display appeared today treacherously from behind Ac clouds. It did not last long, as Ac came to veil it again. 14 frames stack from 5 minutes.

Odd radius halos from Austria

On 27th of April 2009 during the hours before noon an almost complete 23° ring was visible and also both 18° lateral arcs. All halos were visible without sunglasses. The cirrus was very dense. I know days when pyramidal halos were visible over a big area of Central Europe, but this day there are no other reported observations. The photo above shows the display with unsharp masking, but the original photo is also provided ( 1 ). Later this day only the upper part of the common 22° halo was visible.

Wegener over a large area of Europe

On 18 March, nice halo phenomena with complete and bright parhelic circle and Wegener's anthelic arc were seen in Germany, Austria, Switzerland and France. The extent of the area where the Wegener was observed is remarkable!

Some of my own photos from Brannenburg, Southern Germany can be seen in an album or as a slide show ( 1 - 2 ). More pictures from other observers in West Germany, Austria, Switzerland and France are linked at spaceweather.com and in the German halo forum ( 3 - 4 ).

Elliptical and odd radius halos on the same day

On the way home from work I photographed a bright elliptical halo ( 1 ). Later on as winds from a cold front pushed a lot of low level cumuliform clouds away and I was on the state route when this happened and I held my sunglasses near my car's windshield I could make out a bright arc on top of a halo and a closer look showed another halo. I pulled off on to a small road and got to watch a half decent odd radius halo. in all I got 9, 18, 20, 23, and faint 35d halos and a bright upper 23d plate arc ( 2 - 3 ).
