GCN Circular 4727
W. Li, University of California, Berkeley, on behalf of the KAIT GRB team, report: We report further analysis of the KAIT observations of GRB 060210 between 1 to 48 minutes after the burst. The optical afterglow showed an interesting evolution: it was nearly flat (with unfiltered mag of about 18.1) between t = 1 to 5 minutes, brightened to mag 17.7 at t = 9 minutes, then began a fast power-law decline between t = 10 to 48 minutes with an index of -1.05 +/- 0.05. A light curve for the optical afterglow is at http://astron.berkeley.edu/~weidong/grb060210.lc.gif The figure showed both the unfiltered and I-band light curve of the OA, both calibrated to USNO B1.0 red magnitudes.
