GCN Circular 13591
J. Gorosabel (IAA-CSIC), N. Huelamo (CAB-CSIC), R. Sanchez-Ramirez (IAA-CSIC), A. de Ugarte Postigo (IAA-CSIC, DARK), T. Kruehler (DARK), A.J. Castro-Tirado (IAA-CSIC), J.C. Tello (IAA-CSIC), M. Jelinek (IAA-CSIC), report on behalf of a larger collaboration: "I-band observations conducted with the Calar Alto 1.23m telescope at 21:41:19.1--22:04:02.4 UT (obs started ~13 minutes post GRB) for GRB 120805A reveal no object inside the XRT position (GCN Circ. 13588) down to I~18 (Vega). However, we note the presence an object located at RA(J2000)=14:26:09.12, DEC(J2000)=05:49:31.7 (error of ~0.5" in both coordinates) with a magnitude of I~17.5 which seems not to be at the SDSS. Given the lack of a refined XRT position yet, we are cautious about the possible relation of this object with the GRB 120805A optical afterglow."
