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.
