TITLE: GCN CIRCULAR NUMBER: 7907 SUBJECT: GRB 080625: Further observations from OSN DATE: 08/06/26 07:25:24 GMT FROM: Antonio Deugarte at IAA-CSIC A. de Ugarte Postigo (ESO), F. Aceituno, A.J. Castro-Tirado, J. Gorosabel (IAA-CSIC) report on behalf of a larger collaboration: We have observed again the field of GRB 080625 (Pacciani et al. GCN 7903) using the 1.5m OSN telescope at Sierra Nevada Observatory (Granada, Spain) at a mean epoch of 14.76h after the burst. The object identified by Immler et al. (GCN 7905) is well detected in this and in our previous epoch (GCN 7904). A preliminary photometry against USNO-B1.0 stars shows the object decaying, as seen in the following table: t-t0 (hours) Exp (s) I mag 8.325 4x300 19.3+/-0.2 14.769 3x300 20.0+/-0.2
