A mid-summer multihalo in Finland

This display was observed on 1 July 2009 in Tampere, Finland. The most prominent features were the bright upper tangent arc (contributing to a partial circumscribed halo) and the parhelic circle. A faint Wegener arc can be seen rising above the upper tangent arc. The sun elevation was 46 degrees. More photos on Jari Luomanen's website (1).

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 ).

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.
