TITLE: GCN CIRCULAR NUMBER: 14324 SUBJECT: GRB 130305A: optical upper limit in Mondy observatory DATE: 13/03/17 15:30:22 GMT FROM: Alexei Pozanenko at IKI, Moscow A.Volnova (SAI MSU/IKI), R. Burenin(IKI), E. Klunko (ISTP), A. Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration: We observed We imaged the location of the Swift (Cummings et al., GCN 14257), Fermi (Guiriec et al., GCN 14260; Yu et al., GCN 14261), and Konus (Golenetskii et al., GCN 14262) GRB 130305A with AZT-33IK telescope of Sayan observatory (Mondy) on March 05 between (UT) 20:44:08 - 22:17:04. We took several images in R-filter of 100 s exposure under unfavorable seeing (FWHM) of about 4.2 arcsec. We do not detect any sources within the XRT error circle (Malesani et al., GCN 14263). A photometry of a combined image is following UT start, t-t0 Filter Exp. OT UL (3 sigma) (mid, days) (s) 20:44:08 0.41071 R 35x100 n/d 21.4 The photometry is based on SDSS DR8 star SDSS J074702.42+520103.3 07:47:02.43 +52:01:03.4 R = 16.94
