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 ).
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.
