Cenko (UC Berkeley) reports on behalf of a larger collaboration:\n\nWe have imaged the error circle of GRB110213A (D'Elia et al., GCN\n11705) with the automated Palomar 60 inch telescope.  Observations began\nat 05:19 UT (~ 2 minutes after the burst trigger time) and were taken in\nthe r' filter.  We detect a bright source at the location of the UVOT\nafterglow, with coordinates:\n\n   02:51:51.43   +49:16:23.3\n\nUsing several USNO-B1 field stars for comparison, we measure a magnitude\nof R ~ 17.1 at this time.  Observations are ongoing.",
