GRB 230116D: SAO RAS observations of OT brightening
Abstract
We observed the field of the GRB 230116D (Sonbas et al. GCN #33176) with the SAO RAS 1-m telescope Zeiss-1000 + CCD-photometer in Rc band. Inside the XRT error circle we detected new transient object reported by Zhu et al. (GCN #33177) and Nazarov et al. (GCN #33178) with the coordinates R.A. = 06:34:28.2 Dec. = +49:52:20.5 (+/- 0".3, J2000) and brightness R = 19.93 +/- 0.07 (T - T0 = 0.9378h), R = 19.72 +/- 0.06 (T - T0 = 1.4236h) Preliminary photometry is based on R2 magnitudes of nearby USNO-B1 stars. Further observations are ongoing and encouraged.
