Circumzenithal Arc on July 6th, 2010
On the evening of July 6th, 2010, a complete and very homogenous circumzenithal arc could be observed from Trier. The parhelia were very faint and for a short moment a faint bluish 120° parhelion was visible. There were no other halos that could be detected with the bare eye.
