GCN Circular 27846
Daniele B. Malesani (DTU Space), Tapio Pursimo (NOT), Charles L. Steinhardt (DAWN/NBI), report: We observed the field of GRB 200529A (D'Elia et al., GCN 27845) using the Nordic Optical Telescope equipped with the ALFOSC camera. In a single 300-s image, starting on May 29.052 UT (18.9 min after the GRB), we detect a bright point source just outside the currently available XRT position, which is not visible in the archival Pan-STARRS images of the same field. We measure for this object the following position (J2000): RA = 15:55:03.21 Dec = -11:04:26.2 By comparison with nearby stars from the Pan-STARRS catalog, we measure a magnitude r = 20.00 +- 0.02. We conclude that this object is the optical afterglow of GRB 200529A.
