G. G. Williams (MMTO) and P. A. Milne (Steward Observatory), on behalf of
the Super-LOTIS collaboration, report:
Further analysis of the 0.6-m Super-LOTIS observations (GCN 4728) of the
error box of GRB060210 (GCN 4724) yield detections of the optical
afterglow (GCN 4723 and GCN 4725) in the summed R-band data. The summed
images include a stack of five 10s exposures and a stack of five 20s
exposures. The following table lists the mid-time of the stacked
exposures and the resulting photometry using USNO-B1 stars:
t_mid (UT) exp_t t_mid - t0 (s) R
-----------------------------------------------------------------
05:00:24.3 5 x 10 s 94.5 R = 18.25 +- 0.29
05:02:14.5 5 x 20 s 204.7 R = 18.30 +- 0.21
Analysis is ongoing.
