A. S. Moskvitin and O. A. Maslennikova (SAO RAS)
report on behalf of the GRB follow-up team.
We observed the field of Swift GRB 240112C (Eyles-Ferris et al.,
GCN #35522) with the 1-m telescope of SAO RAS equipped with the CCD
photometer. We obtained 21 x 60 sec. images in Rc band on January 13,
03:00:16--03:34:31 UT (t_mid - T0 = 0.40277 days) under mediocre
weather conditions.
We did not detect any significant source at the OT position
down to the limiting magnitude R_lim = 21.1
(based on R2 magnitudes of nearby USNO-B1 stars).
