Duscha, M. Muehlegger, N. Primak, G. Kanbach, H. Steinle (MPE Garching) of the OPTIMA-Burst Team report the following: "OPTIMA-Burst at the 1.3m Skinakas Observatory, of the University of Crete, Greece observed the Swift XRT-errorcircle of GRB 060912 (GCN Circ. 5558, C.P. Hurkett et al.) starting at 19:21UT (~5.5h after the Burst). We detect a source consistent with the source reported by C.P. Hurkett et al. and M. Zhai et al. (GCN Circ. 5560). We estimate the magnitude of the source as R=21.6 +- 0.2 There is no known minor planet brighter than 23 mag within 5' of the source according to MPChecker"
