GCN Circular 33178
S. Nazarov (CrAO), A. Pozanenko (IKI), S. Belkin (IKI, HSE), N. Pankov (HSE) report on behalf of IKI GRB FuN: We observed GRB 230116D (Sonbas et al., GCN 33176) with Sintez-Newton telescope of CrAO observatory. Observation started on 2023-01-16 (UT) 21:21:41. The series consists of images with an exposure of 120 s in Clear filter. In the first images we detect an object in coordinates (J2000) 06:34:28.01 +49:52:20.35 (with uncertainties of 0.5 arcsec) which is within of the XRT error circle (Sonbas et al., GCN 33176). Preliminary photometry of the afterglow is 19.5 at (UT) 21:41:56. The photometry is based on nearby USNO-B1.0 (R2) stars. There is no object in PS1 and DSS2 catalogues at this coordinates. Therefore we suggest the object is the afterglow of GRB 230116D. Observation is continuing.
