TITLE: GCN CIRCULAR NUMBER: 12098 SUBJECT: GRB 110625A: 1.23m CAHA I-band observations DATE: 11/06/26 23:50:14 GMT FROM: Javier Gorosabel at IAA-CSIC J. Gorosabel (IAA-CSIC), V. Terron (IAA-CSIC), P. Ferrero (IAC), M. Jelinek (IAA-CSIC), P. Kubanek (IAA-CSIC & U. Valencia), M. Fernandez (IAA-CSIC), report on behalf of a larger collaboration: "We observed the field of GRB 110625A (Page et al., GCN 12088) with the 1.23m telescope of Calar Alto observatory. We obtained 45x60s I-band images on June 25.88457--25.93027 UT (i.e, starting 5.32 min after the trigger). In the co-added image, we detect a source at RA(J2000)=19:06:55.88, DEC(J200)=06:45:19.4 (+/-0.5") which is consistent with the objects reported by Im et al. (GCN 12095) and Filgas et al. (GCN 12096). Using as photometric reference the USNO B1.0 star located at RA(J2000) = 19:06:56.17, DEC(J2000)=06:44:25.9 with I=16.56, we derived a preliminary magnitude of I=20.6 (Vega system) for the object inside the XRT error circle. This magnitude might indicate some degree of fading with respect to the i-band AB mag reported by Filgas et al. (GCN 12096). However, we are still cautious on the possible association of this object with the GRB. Further multi-band observations are encouraged."
