Adria C. Updike (NASA/GSFC), Dieter H. Hartmann (Clemson University),
Brian Murphy, and Andrew N. Darragh (Butler University) report:
We observed the field of GRB 110212A (D'Elia et al., GCN 11699) with the
SARA-North 0.9m telescope at KPNO beginning 58 minutes after the trigger
under good conditions. We obtained 24 minutes of stacked exposures in the
R band and 6 minutes of stacked exposures in the I band.
We detect no new sources within nearly 2 sigma of the BAT error circle
down to limiting magnitudes of R > 20 and I > 19 relative to the USNO B1.0
catalog.
