TITLE: GCN CIRCULAR NUMBER: 13081 SUBJECT: GRB 120320A , optical observations DATE: 12/03/21 04:49:14 GMT FROM: Shashi Bhushan Pandey at ROTSE Brajesh Kumar, Vijay Kumar Bhatt and S.B. Pandey (ARIES, Nainital, India, on behalf of larger Indian GRB collaboration) We observed the field of GRB 120320A (trigger=518200, Markwardt et al., GCN 13071) with the 1.04m telescope at ARIES Nainital starting at UT 18:39:42 on 20-03-2012. Three images in R_c pass-band (300 sec each) were obtained. The photometry of the co-added R_c frame did not reveal any new source within the XRT error-box (Melandri et al., GCN 13079). The 3-sigma upper limit of the co-added frame was found to be ~ 19.5 mag. The photometry was done in comparison to nearby USNO- B1 stars. This massage may be cited.
