14 August 2007 - At the edge of a large, smooth-structured Altocumulus bank, elliptical halos appeared at 1100, and from 1113 to 1120 UTC. In the first stage, the halo was complete and quite bright, although hardly coloured. It remained too short to get the camera ready. In the second stage, the halo was quite bright as well, and uncoloured, and sometimes partly covered by the continuously passing-over Altocumulus edge. Several photographs were able to be made (Nikon D80, AF-S Nikkor justed on 45mm). At 1113 UTC there were sections of two different elliptic halos visible. The inner remainded visible and was complete, even shining through the Altocumulus. The Altocumulus became increasingly dense and halos disappeared at 1120 UTC. Solar elevations from 51.7 to 51.9degs.
