Details:
Thin cirrus clouds on a wintry morning, sun 21 degrees above horizon, 10 am local time -- perfect conditions for seeing sun halos! Ran back in the house to get my point-and-shoot Canon A1200 camera, and within minutes, an array of beautiful half-sky arcs and halos were visible. Some celestial symmetry for 12-12-12.
Parahelia (sundogs) at E and W edges of 22-degree halo -- sometimes as intense as searchlights, pointing away from the sun along the parahelic arc; a very intense upper tangent arc, looking really like a giant lozenge or the pair of lips that hangs above the stage at Carnegie Hall to enhance acoustics -- or...might this have been a Parry arc? Finally, an at times very bright circumzenithal arc, overhead, very distinctly diverging from a shared tangential central point with a supralateral arc that from minute to minute changed greatly in aspect -- one moment hardly visible, the next clearly arcing halfway down toward the horizon, framing the entire spectacle. Transfixed, I was an hour late for work!
