On August 31, 2006, clouds moved in destroying all hopes for meteor observations in the night. The halo display in the high clouds close to sunset (1725 UT, Sun elevation approximately 3 deg) observed by Jürgen Rendtel from Marquardt (west of Berlin, 13.0 deg E, 52.5 deg N) included intense V-shaped upper tangent and Parry arcs. Another bright coloured 'spot' of about 3 deg apparent size was found to be part of the supralateral arc and Tape's halo. The image processing by Claudia Hinz using unsharp masking also revealed the convex Parry arc.
