Halos and Contrail on August 16th, 2003
On August 16th, 2003, Trier witnessed a moderate halo display comprising a 22° halo, parhelia, a circumzenithal arc and, later on, an uncomplete circumscribed halo and parts of the parhelic circle. While the halo display was rather mediocre, the contrail shadows projected on a very thin and homogenous cloud layer were impressive. Canon Powershot G2, processed with Adobe Photoshop 6.0.
