Transient Detections and Other Real-Time Data Processing from MASTER-VWF Wide-Field Cameras

Figure 14

Coadded images taken 30 seconds before (a), during (b), and 30 seconds after (c) GRB081102. Each frame is a coadd of 12 images (six images from each camera)—60 seconds exposure for each frame. FOV 3^∘×3^∘ on the frame edge. So strange stars shape is connected with off-axis aberrations. Animation is available here: http://observ.pereplet.ru/images/GRB081102/grb_film.html.
