GCN Circular 4876
B. Schmidt (ANU), Derek Fox (Penn State), and Edo Berger (OCIW), on behalf of a larger collaboration report, "We have obtained a series of r-band images with Gemini-S + GMOS between UT Mar 13.058 and March 13.096 of GRB 060313 (Pagani et al. GCN 4867) of the OT-candidate of Levan and Hjorth (GCN 4871). Comparison with USNOA2 star located at RA=04:26:28.906 DEC=-10:51:00.16 (J2000) R=18.1 shows the OT-candidate to be 2.19 magnitudes fainter than the star at Mar 13.058, and 2.26 mags fainter at Mar 13.096, a marginally significant difference. It is possible that an underlying host galaxy is significantly affecting the photometry. We would like to thank the Gemini Staff for their help in executing these Target of Opportunity observations."
