This image, which was captured from my front yard on the afternoon of 2009/12/18 with a Canon EOS Digital Rebel DSLR and 18-55mm Canon EFS zoom lens, features (from top to bottom) the 22 degree solar halo, the sundog to the left of the Sun, the upper tangent arc, and the circumzenithal arc. See http://www.atoptics.co.uk/halo/common.htm for further information on ice halo phenomena.
