collaboration.
The 0.6m automated Super-LOTIS telescope, located at Steward Observatory's
Kitt Peak site, responded to Swift trigger 163438, GRB051111A. The first
image began at 06:00:17.4 UT, 35.9 s after the burst. We clearly detect
the OT identified by W. Rujopakarn et al. (GCN 4247) and find that it has
faded considerably in images taken 15 minutes after the burst. The
approximate R band magnitude in the first 10 second exposure was
determined using the USNO B1 catalog.

Observations and analysis are continuing.
