GCN Circular 22269
D. A. Perley (LJMU), D. Malesani (DARK/NBI), K. Heintz (Univ. Iceland, DARK/NBI), A. de Ugarte Postigo (IAA-CSIC, DARK/NBI), and J. J. Lehiten (MPS) report on behalf of a larger collaboration: We obtained observations of GRB 171222A (Racusin et al., GCN 22265) using StanCam on the Nordic Optical Telescope, beginning at 00:08:31 UT on 2017-12-23. Imaging was obtained in both R and I bands. In the raw images we identify an optical source, not visible in pre-imaging from Pan-STARRS, at the following location within the XRT error circle (Osborne et al. GCN 22266): RA = 09:53:06.73 Dec = +35:37:35.5 We suggest that this source is the optical afterglow of GRB 171222A. Provisional photometry relative to nearby USNO stars gives a magnitude of R = 21.44 +/- 0.09 (at 7.67 hours after the GRB trigger).
