Elliptic halos over Deventer
Predominantly incomplete but brightly colored elliptical halos over Deventer, the Netherlands on Sunday 23/4. The display occurred in two stages, the first performing one elliptic halo section (vertical radius app. 5degs) from 1030-1037 UT, the second from 1048 to 1100 UT, during some minutes including a fainter and smaller but complete inner elliptic halo (vertical radius app. 3degs). By the time shape was somewhat varying. Most striking was the coloration, with dominating red to orange but also yellow and blue outside. Sun elevations were 48.3degs at 1030, and 49.6degs at 1055UT.
