TITLE: GCN CIRCULAR NUMBER: 12408 SUBJECT: Skynet observations of GRB 110928A DATE: 11/09/29 04:14:54 GMT FROM: Aaron LaCluyze at U.North Carolina J. Haislip, K. Ivarsen, A. LaCluyze, K. McLin, D. Reichart, J. Moore, T. Cromartie, R. Egger, A. Foster, M. Nysewander, A. Oza, E. Speckhard, A. Trotter, and J. A. Crain report: Skynet observed the field of GRB 110928A (Hoverston et al., GCN 12394) with the GLAST Optical Robotic Telescope (GORT) at the Hume observatory in California beginning roughly 75 minutes after the burst. We do not detect any uncatalogued sources. Stacking only images that increase the limiting magnitude yields: mean mean time time 3-sigma since since limiting trigger trigger (days) telescope exposures filter mag 3.186 h 0.13277 GORT 19 x 80 s Ic 20.0 3.400 h 0.14166 GORT 23 x 80 s Rc 21.0 This message may be cited.
