GRB 210212A: Gemini South optical observations
Abstract
We observed the field of GRB 210212A (Troja et al., GCN Circ. 29487) with the Gemini South telescope beginning 2021-02-13 02:16:45 UT, approximately 0.91 days post-burst. We obtained 9x120 s exposures in r-band performed with good weather conditions and at an airmass of 1.5 Within the enhanced Swift-XRT error circle (Beardmore et al., GCN Circ. 29489) we detect a single extended source with r = 23.17 +/- 0.05 AB mag, previously reported as the putative host galaxy (Heintz et al., GCN Circ. 29498). A weak optical source with r = 25.3 +/- 0.2 AB mag lies at the edge of the XRT error circle, 6 arcsec away from the putative host. We cannot determine whether it is related to the GRB at present time. Magnitudes are calibrated against the Pan-STARRS DR1 catalog and not corrected for Galactic extinction. We thank the Gemini South staff for rapidly executing these observations.
