Molotov (KIAM) report on behalf of larger\nGRB follow-up collaboration:\n\nWe observed the field of GRB 190202A (Lien , et al., GCN  23830)   with \nZeiss-1000 1-m telescope of Koshka Observatory starting on Feb. 02  (UT) \n02:40:34 in  R-filter.   We detect the optical afterglow  (Lien , et al., \nGCN  23830) in coordinates (J2000) 11:06:00.60  +09:22:36.2 (uncertainiies \nin both coordinates of 0.5 arcsec) coinciding with reported  in GCN 23830. \nPreliminary photometry of the afterglow at 2019-02-02 02:49:35 is R=17.8 +/- \n0.15.\n\nThe photometry is based on several nearby USNO-B1.0 stars.",
