TITLE: GCN CIRCULAR NUMBER: 14670 SUBJECT: GRB 130515A: Further Gemini Observations DATE: 13/05/16 23:23:55 GMT FROM: S. Bradley Cenko at Caltech S. B. Cenko (UC Berkeley) and A. Cucchiara (UCSC) report on behalf of a larger collaboration: We re-imaged the field of GRB 130515A (Malesani et al., GCN 14650) with the Gemini Multi-Object Spectrograph mounted on the 8 m Gemini South telescope. Images were obtained in the r' filter beginning at 4:38 UT on 2013 May 16 (~ 1.1 days after the Swift trigger). Comparing with our previous epoch of observations (Cenko et al., GCN 14656), we find no evidence for variability in or around the enhanced XRT error circle (Beardmore et al., GCN 14654). Specifically, we note that the three sources S1, S2, and S3 identified previously (Xu et al., GCN 14653, Schmidl et al., GCN 14655, Levan et al., GCN 14677) all maintain a constant brightness level. Using digital image subtraction, we limit the optical afterglow at the time of our first epoch of observations (~ 38 min after the Swift trigger) to be R > 23.7 mag (calibrated with respect to nearby USNO-B1 point sources). We thank the Gemini staff for the prompt execution of these observations.
