(IKI), A. Volnova (IKI), I. Molotov (KIAM) report on behalf of larger
GRB follow-up collaboration:
We observed the field of GRB 190202A (Lien , et al., GCN 23830) with
Zeiss-1000 1-m telescope of Koshka Observatory starting on Feb. 02 (UT)
02:40:34 in R-filter. We detect the optical afterglow (Lien , et al.,
GCN 23830) in coordinates (J2000) 11:06:00.60 +09:22:36.2 (uncertainiies
in both coordinates of 0.5 arcsec) coinciding with reported in GCN 23830.
Preliminary photometry of the afterglow at 2019-02-02 02:49:35 is R=17.8 +/-
0.15.
The photometry is based on several nearby USNO-B1.0 stars.
