Belkin (IKI) report on behalf of IKI-FuN:
We observed the field of the GRB 190114B (Siegel et al., GCN 23686) with
AZT-33IK telescope of Sayan observatory (Mondy). We started observations
on Jan. 14 (UT) 20:28:30, i.e. 57 minutes after burst trigger. Within
the enhanced XRT position (Goad et al., GCN 23691) we detect the object
which is absent in SDSS catalog. Coordinates of the object are (J2000)
11:39:29.84 +18:53:27.8 with uncertainty 0.5 arcsec in both coordinates. The
brightens of the object is R ~ 20.1m at (UT) 20:28:30. We suggest the object
is the afterglow of GRB 190114B. The photometry is based on nearby SDSS
DR12 stars, Lupton transformation.
