TITLE: GCN CIRCULAR NUMBER: 16571 SUBJECT: GRB 140709B: update of Khureltogot optical upper limit DATE: 14/07/10 16:35:49 GMT FROM: Alexei Pozanenko at IKI, Moscow A. Volnova (IKI), S. Schmalz (AIP), N. Tungalag (Research Center of Astronomy and Geophysics MAS), I.Molotov (KIAM), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: After receiving a full data set we report details of the observation of the field of GRB 140709B (Swenson et al., GCN 16551) with ORI-40 telescope of Khureltogot observatory. We started observation on July 09 (UT) 15:31:51 and obtained 60 unfiltered images of 60 s exposure. Within enhanced XRT error circle (Goad et al., GCN 16556) we do not detect any new object neither in separate, nor in stacked images. Details of a photometry is following UT start t-T0,d Exp,s Filter Up_lim (3 sigma) 15:31:51 0.01334 5*60 None 18.9 15:31:51 0.01940 20*60 None 19.5 The photometry is based on SDSS star J094401.61+633253.8 assuming R=16.010+/-0.013 (using gri -> R Lupton transformations).
