- Аннотация: We observed the field of GRB 230414B detected by Swift (D'Ai et al., GCN 33612) with the SAO RAS 1-m telescope Zeiss-1000 + CCD photometer. We obtained several images in Rc band. The GRB OT (Pankov et al., GCN 33615; Lu et al., GCN 33616; Raman et al., GCN 33618; Ghosh et al., GCN 33620) is clearly detected in the stacked frame with the brightness of R = 19.8 +/- 0.1 (T_mid - T0 = 3.68 hours). This preliminary photometry is based on R2 magnitudes of nearby USNO-B1 stars. The OT magnitude is not corrected for the Galactic extinction.
