D.B. Fox (Penn State) and S.B. Cenko (Caltech) report on behalf of a larger collaboration: "We have imaged the XRT localization region for GRB060210 (Swift Trigger #180977) with the robotic Palomar 60-inch telescope, in two 60-second exposures beginning roughly 5 minutes after the BAT trigger. We identify a single point-like, bright, stationary source consistent with the XRT position, at coordinates: R.A. 03:50:57.41, Dec +27:01:34.4 (J2000) with a coordinate uncertainty of less than 2" in each axis. The estimated brightness of the transient at t+5.5 minutes is R=18.3 +/- 0.1 mag by reference to USNO B-1.0 catalog magnitudes of stars in the field."
