Spiridonova (SAO RAS)\nreport on behalf of the GRB follow-up team.\n\nWe observed the field of GRB 240123A (D'Ai et al., GCN #35602;\nScotton, GCN #35610) with the 1-m telescope of SAO RAS equipped\nwith the CCD photometer. We obtained 16 x 300 sec. images in Rc\nband on Jan 25, 01:55:52 -- 03:30:49 UT (t_mid - T0 = 1.6511 days).\n\nThe OT (D'Ai et al., GCN #35602; Pankov et al., GCNs #35605, #35609\n#35620; Sasada et al., GCN #35618) is detected in our stacked frame\nwith the brightness of R = 22.0 +/- 0.2.\n\nThe photometry is based on R2 magnitudes of nearby USNO-B1.0 stars.\n",
