Subject
GRB060210: Optical Observations
Date

From

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.
