GCN Circular 12745
S. B. Pandey, Vijay Kumar Bhatt, Brajesh Kumar and Ram Kesh Yadav (ARIES, NainiTal, India, on behalf of larger Indian GRB collaboration). We have observed GRB 111228A field (Ukwatta et al., GCN 12737; Briggs and Younes, GCN 12744) with the 1.04m telescope at ARIES NainiTal starting ~1.9 hours post-burst. Several sets of exposures varying 100s to 300 s each were taken in Bessel filters. The afterglow candidate (Xin et al., GCN 12738) is visible in individual frames. Preliminary photometry of the R_c band data in comparison to nearby USNO stars, indicates that the afterglow candidate has decayed by ~ 0.7 mag in ~ 3.5 hours of observations. This corresponds to a temporal decay index of ~ 0.3, similar to what has been noticed by Klotz et al. (GCN 12742). Further observations are continued. This message may be cited.
