Cenko (Caltech) reports on behalf of a larger collaboration: We have imaged the field of GRB070311 (Mereghetti et al., GCN 6189) with the automated Palomar 60-inch telescope. Observations were taken in the i' filter at a mean epoch of approximately 3:05 11 March UT (~ 72 minutes after the burst). We detect a faint source at the position of the NIR afterglow (Covino et al., GCN 6190). Using several USNO-B objects in the field, we measure a magnitude of I ~ 21.5.
