GCN Circular 11229
A. Melandri (INAF-OAB), D. Kopac (U. Ljubljana) and Z. Cano (LJMU) report on behalf of a large collaboration: The Faulkes Telescope North automatically began observing Swift GRB 100906A (trigger = 433509, Markwardt et al., GCN 11227) on September 06,13:53:03 UT, about 3.5 minutes from the GRB trigger time. We clearly identify an uncatalogued object at the following position: RA(J2000.0): 01:54:44.09 Dec(J2000.0): +55:37:49.5 The position is consistent with UVOT candidate and the object is clearly fading. Preliminary photometry gives a magnitude of R=15.5 +/- 0.1 @800 s after the burst event. Observations are going on.
