TITLE: GCN CIRCULAR NUMBER: 14320 SUBJECT: GRB 130315A: SALT optical observations DATE: 13/03/16 15:02:46 GMT FROM: Timothy Pickering at SALT T. E. Pickering, P. Vaisanen, V. van Wyk report on behalf of SALT: We have observed the field of GRB 130315A (Evans et al. GCN 14311) using the RSS imager/spectrograph at the Southern African Large Telescope (SALT). The observations began at 17:40 UT, just under 5 hours after the initial Swift trigger. Imaging was performed using a broadband filter with a blue cutoff at 4600 A and three narrow-band filters centered at 4820 A, 6530 A, and 8175 A. The data were somewhat hampered by scattered clouds and mediocre seeing. Comparison to a DSS2 red image finds no evidence of a new source within the error circle of the refined XRT position (3.6"; Page et al. GCN 14317). The limiting magnitude of our best images is roughly ~0.5 mag deeper than the DSS2 image which gives a detection upper limit of r ~ 21 based on comparison with nearby stars in the GSC 2.3.
