Lowitz Arc in Bochum, Germany

On September 6, 2007, Peter Krämer observed a relatively bright left Lowitz arc in the skies over Bochum in the German Ruhr area. The arc (picture with unsharp mask) stayed visible for about 20 minutes, stretching away upwards and downwards from the left sundog.
Apart from the sundogs and Lowitz arc, there was also a faint 22°-halo visible, together with the upper tangent arc and circumzenital arc.
One hour later, after Lowitz arc and CZA had already faded away, the upper tangent arc became rather bright, and also parts of the supralateral arc showed up.
