E. Mazaeva (IKI), A. Pozanenko (IKI), E. Klunko (ISTP), A. Volnova (IKI), S. Belkin (IKI) report on behalf of of larger GRB follow-up collaboration:
We observed the field of GRB 190114A (LaPorte et al., GCN 23677) with AZT-33IK telescope of Sayan observatory (Mondy). We obtained several images in R-filter starting on Jan. 14 (UT) 11:43:08, i.e. ~ 9 hours after the BAT trigger. The afterglow (Siegel et al., GCN 23678; de Ugarte Postigo et al., GCN 23680; Bolmer et al., GCN 23682; de Ugarte Postigo et al., GCN 23687; Selsing et al., GCN 23697) is clearly detected in a stacked image.
