GRB 241112B: AbAO optical upper limit

We observed the field of GRB 241112B (SVOM/ECLAIRs Commissioning Team & SVOM JSWG, GCN 38173; Evans, GCN 38174; Kumar et. al, GCN 38175; Du et. al, GCN 38176; SVOM/VT commissioning team & SVOM JSWG, GCN 38179; SVOM/GRM team & SVOM JSWG, GCN 38180; Turpin et. al, GCN 38181) with 70-cm AS-32 telescope of Abastumani observatory (AbAO). The observations began on 2024-11-12 at 15:03:45 UT. In total, the series of 101x60 s frames was taken in the R-filter using CCD-photometer FLI PL4240. We do not detect the optical afterglow (SVOM/VT commissioning team & SVOM JSWG, GCN 38179; Turpin et. al, GCN 38181). The preliminary photometry is as follows: Date UTstart Exptime t-T0 Filter OT Err UL (s) (mid, days) (3sigma) 2024-11-12 15:03:45 98*60 0.205139 R n/d n/d 19.6 The magnitudes were calibrated using nearby stars of USNO-B1.0 (R2 magnitudes).
