G. G. Williams (MMTO) and P. A. Milne (Steward Observatory), on behalf of
the Super-LOTIS Collaboration, report:
The robotic 0.6-m Super-LOTIS telescope began observing the error box of
GRB060210 (Swift Trigger 180977, GCN 4724) at 04:59:44.9 UT, 55 seconds
after the burst. Our initial observations include 5 x 10s exposures, 5 x
20s exposures, and 30 x 60s exposures, all in the R-band. We do not
detect the afterglow reported by Fox et al. (GCN 4723) and Li et al. (GCN
4725) in our earliest exposure to the following 5-sigma limiting magnitude
using USNO-B1 stars:

Additional multi-band observations and analysis including image stacking
are ongoing.
