TITLE: GCN CIRCULAR NUMBER: 38028 SUBJECT: GRB 241026A: SAO RAS optical observations DATE: 24/11/01 10:04:47 GMT FROM: Moskvitin Alexander at SAO RAS <mosk@sao.ru> A. S. Moskvitin, A. S. Vinokurov (SAO RAS), A. S. Pozanenko (IKI), N. Pankov (IKI, HSE) report on behalf of the GRB follow-up team. We observed the field of GRB 241026A (The Fermi GBM team, GCN 37894; Melandri et al., GCN 37896, Li et al., GCN 37909; Zhang et al., GCN 37921; Zhang, Xiong and Wang GCN 37924; Pal et al., GCN 37929; Barthelmy et al., GCN 37971) with the 6-m telescope of SAO RAS equipped with the focal reducer Scorpio-I on October 30, 17:38:47--18:14:14 UT (t_mid-T0 = 3.8014 d). The OT (Moskvitin et al., GCNs 37899, 37916, 37953; Watson et al., GCN 37900; Zheng & Filippenko GCN 37903; Shrestha et al., GCN 37913; Mo et al., GCN 37915; Mohan et al., GCN 37918; Izzo et al., GCN 37925; Wang et al., GCN 37928, Rossi et al., GCN 37969) is detected in a stack image of 42 x 30 sec. The brightness of the OT is R = 23.9 +/- 0.2, calibrated against nearby USNO-B1.0 stars (R2 magnitudes) and not corrected for Galaxy extinction.
