TITLE: GCN CIRCULAR NUMBER: 13505 SUBJECT: GRB 120722A: 1.5m OSN I-band observations DATE: 12/07/23 02:37:11 GMT FROM: Javier Gorosabel at IAA-CSIC F. Aceituno (OSN, IAA-CSIC), R. Sanchez-Ramirez (IAA-CSIC), A. de Ugarte Postigo (IAA-CSIC, DARK), J. Gorosabel (IAA-CSIC), A.J. Castro-Tirado (IAA-CSIC), report on behalf of a larger collaboration: "We observed the field of the GRB 120722A XRT error circle (Melandri et al., GCN 13499; Evans et al., GCN 13502) with the 1.5m telescope at the Observatorio de Sierra Nevada, Granada, Spain. The observations were conducted in the I-band with a total exposure time of 16x300s on July 22.86617-22.92716 UT (7.9--9.4 hours post GRB). No object is detected inside the XRT error circle down to I~21 (Vega mag, calibrated against USNO-B1.0). We note the presence of a faint object close to the XRT error circle border located at RA(J2000)=15:21:59.19, Dec(J2000)=+13:15:05.0 (+/-0.9") which seems also present at the SDSS."
