Arizona and NEW MEXICO A mysterious cloud suddenly appeared in the sky on November 24, 2015.
Details: I was observing Comet Catalina, when I noticed this thing halfway up towards Venus. Coordinates: RA 14:10:15, Dec -05:20:41, lasting for at least a half an hour after 5:40 AM. It was huge, easily naked eye, and scary! Nikon D600, ISO6400, 30 second exposure, Stellarvue SVQ100, f/5.8, 580 mm focal length. I have more images.
Re-achieving critical mass. Until then it's only stardust and emptiness.
