GRB 240123A: SAO RAS optical observations
Abstract
We observed the field of GRB 240123A (D'Ai et al., GCN #35602; Scotton, GCN #35610) with the 1-m telescope of SAO RAS equipped with the CCD photometer. We obtained 12 x 300 sec. images in Rc band on Jan 24, 02:15:54 -- 03:42:02 UT (t_mid - T0 = 0.66194 days). The OT (D'Ai et al., GCN #35602; Pankov et al., GCNs #35605, #35609; Sasada et al., GCN #35618) is clearly detected in our stacked frame with the brightness of R = 21.12 +/- 0.09. The photometry is based on R2 magnitudes of nearby USNO-B1 stars.
