Today (on 3. February 2006) Prague citizens had a nice morning surprise - diamond dust. HOP members (Tomas Trzicky and Katerina Juzova) and others observed bright sundogs, 22 deg halo, circumzenithal arc, faint parhelic circle and very nice 120 deg parhelia (see photo by Tomas Trzicky). Halos appeared even in an internet newspapers
here and a guy called to the radio: "I see rainbows!". All photos and videos are
here and
here.
The display looks like there was not much crystals on the ground, but rather the crystal layer was some tens or perhaps hundreds meters above ground.
