1999/12/11 15:20 EST, Sun altitude: 13 degree 8 minute. This halo display features some less common halos, including a Parry arc, a possibly Parry infralateral brightening, and a 46 degree halo. The display also includes a 22 degree halo, two parhelia, a upper tangent arc, and a circumzenith arc.

Ross Park Mall, Pittsburgh. I was in a car moving with the traffic, and thus couldn't get a static view. So the images are incomplete mosaics. 15 minutes later when we finally got to a parking lot, the halos were gone. Images taken with Sony camcorder.
