GCN Circular 13586
R. Chornock and E. Berger (Harvard) report on behalf of a larger collaboration: We observed the position of the X-ray afterglow of the short GRB 120804A (Lien et al., GCN 13573) using GMOS on the Gemini-North 8-m telescope. Observations began at 05:47 UT on 2012 August 4 (approximately 4.9 hours after the BAT trigger). We obtained 11x180s of observations in both the r and i filters. We find a pair of faint sources in the i band observations within the enhanced XRT position (Osborne et al., GCN 13577) with coordinates (J2000): S1: 15:35:47.48, -28:46:56.2 S2: 15:35:47.53, -28:46:57.6 with astrometric errors of about 0.3" relative to 2MASS. S1 is slightly brighter than S2 in i. Neither source is detected in r. Further observations are planned in order to search for variability of these sources. We thank the Gemini staff, particularly Chad Trujillo, for their assistance with these observations.
