W. Li, University of California, Berkeley, on behalf of the
KAIT GRB team, report:
The robotic 0.76-m Katzman Automatic Imaging Telescope (KAIT)
at Lick Observatory observed GRB051111 detected with Swift
(Trigger 163438; Sakamoto et al. GCN 4248). A series of
images was automatically obtained starting at 06:00:25 UT
(44s after the burst). The sequence includes a combination of
images taken with the V and I filters, as well as some that
are unfiltered. The OT identified by W. Rujopakarn et al. (GCN
4247) was detected with the following unfiltered magnitudes
(calibrated to USNO B1.0):
UT Start EXP time R mag delta R
06:00:25 15 s 13.40 0.05
06:01:46 20 s 14.32 0.05
Observations and analysis are continuing.
