Moon pyramidal halo complex in Czech Republic

In June when conditions for observing halos aren’t fine because of low full moon elevation, I have had my best observation ever. On cirrostratus veil divided from cumulonimbus cloud firstly appeared 9° halo and later thick halo at 22-24 area. After stacking 20 pictures, it turned out to be 23° and 24° halo. Fragments of 20° halo were not recognizable until stacking photos. Halos were seen at the highest intensity for about half an hour.

Odd radius halos at Crete

These odd radii were a little bit surprising, I didn’t expect something like this at Asimenia beach in Kavroz. I had been waiting for any halos for five days and the first display was directly pyramidal 18°, 20° and 23° halos. Fortunately I had a piece of welding glass because photos I took without this protective glass was totally unusable because of reflections. The display originated at very thin cirrus clouds.

Subparhelia with reflected Lowitz arcs

Bill Burton, USGS, observed nice halo display with very rare reflected Lowitz arcs. Bill: "This photo showing an impressively bright sub-Sun and sub-parhelion was taken from the window of a commercial airliner on a flight from Anchorage to Minneapolis. I was looking down at a thin, cirrus cloud layer over the snow covered farmland of southern Canada when these wonderful halos and arcs appeared. The Sun is above the image, producing this sub-Sun and upward-facing portion of a 22-degree halo. This sub-Sun was brilliant enough to create its own sub-parhelion and 22-degree arc - on the right side of the image. Photo taken on January 11, 2007"
