Asteroid 2012DA14 streaking across the night sky. This is a combined image made from 7 individual shots at an exposure time of 0.5 seconds each. Images were taken consecutively every 3.5 sec. The asteroid was moving from the south (bottom of frame) to the north (top).
The instrument used was the University of Athens Observatory 0.40m f/8 Cassegrain reflector with a SBIG ST-10XME CCD camera and a f/6.3 focal reducer, resulting in a 25x17 arcminutes field of view.
The image is centered at equatorial coordinates: RA: 12h 18m 55s, DEC: +20d 50m 04s
