A. Stefanescu, F. Schrey, G. Kanbach, S. Duscha, M. M�hlegger, N. Prymak, H. Steinle (MPE Munich) of the OPTIMA-Burst Team report the following: "OPTIMA-Burst at the 1.3m Skinakas Observatory, located on Crete, Greece observed the Swift XRT-Errorbox of GRB 060707 at 00:30 UT (3h after the Burst). We detected a faint source at the edge of the XRT-errorcircle (GCN Circular #5285). We estimate the brightness of this source in a 10min white-light image as 20.3+-.5mag. The position of the source is RA 23:48:19 Dec -17:54:18.4 (J2000). There is no source at this position in the USNO-A2 Catalog, and no minor planet according to MPChecker. This source seems compatible with the source reported in GCN Circular 5290"
