Hope you got to see this yourself. The image is not sharp enough to tell, but it was just a sliver (probably less than 5% full) in a near perfect horizontal position, looking like the lips in a smilie.
Wish I'd had my 9mp camera with 10X zoom and a tripod, in which case I could have obtained a much sharper image for you. The Bradley Observatory at Agnes Scott should consider publishing the most interesting image it can obtain on any clear sky night. It would increase awareness of what it offers to the surrounding community, and we'd greatly enjoy the images.
