TITLE: GCN CIRCULAR NUMBER: 13865 SUBJECT: GRB 121011A: optical observations DATE: 12/10/13 04:55:08 GMT FROM: Shashi Bhushan Pandey at ROTSE Brajesh Kumar, Vijay Kumar Bhatt, Archana Soam and S.B. Pandey (ARIES, Nainital, India, on behalf of larger Indian GRB collaboration). Follow-up observations of GRB 121011A (Racusin et al., GCN13845) were done using 1.04m telescope at Nainital in good sky conditions starting at 13:17:03 (UT) on 11-10-2012. Several frames in B, V, R_c and I_c pass-bands were obtained with exposure time of 300 sec each. The optical afterglow candidate (Racusin et al., GCNC 13845) is clearly detected in our frames. The preliminary photometry for the first R_c and I_c frames were 19.59 +- 0.02 mag and 19.14 +- 0.05 mag respectively, calibrated against nearby USNO stars. Further observations are continued.
