Аннотация:We observed the field of the GRB 251002A with the 1-m SAO RAS telescope Zeiss-1000 equipped with the new CCD-photometer. The observations started at 20:31:30 UT, ~17 minutes after the trigger. The optical transient is clearly detected in the individual images with the brightness of R = 17.58 +/- 0.02 (t_mid - T0 = 0.41694 hours).
