TITLE: GCN CIRCULAR NUMBER: 6793 SUBJECT: GRB 070917: R band observations DATE: 07/09/17 16:47:00 GMT FROM: Kuntal Mishra at ARIES,Nainital,India K. Misra, S. B. Pandey and Rupak Roy (ARIES, NainiTal, India, on bahalf of larger Indian GRB collaboration) We have imaged the field of Swift GRB 070917 with the 1.04m telescope at NainiTal ~ 7.5 hours after the burst (Cummings et al. GCN 6791). Observations were performed in R band (5*300 sec) in poor sky conditions. We notice that the field is crowded and a considerable amount of extinction (E(B - V) = 0.45 mag) is there in the burst direction. Visual comparison with DSS-II plate does not show any new source within the refined error-box (Tueller et al. GCN 6792). Photometry of the co-added frame put a 3 sigma upper limit of ~20.5 mag in comparison to the nearby USNO A2.0 star 0900-15768267 (R mag 16.6) This message may be cited.
