TITLE: GCN CIRCULAR NUMBER: 28699 SUBJECT: GRB 201014A: SAO RAS optical observations DATE: 20/10/20 13:32:15 GMT FROM: Moskvitin Alexander at SAO RAS A. S. Moskvitin, V. N. Aitov (SAO RAS) on behalf of GRB follow-up team report. We observed the field of GRB 201014A, Swift trigger 1000255 (Ambrosi et al., GCN 28623) with the 1-m telescope of SAO RAS, Zeiss-1000 + Multi-Mode Photometer-Polarimeter. We obtained 6 x 300 sec. images in Rc band on October 15, 21:11:44--21:43:50, t_mid - T0 = 0.9439 days since trigger. Inside the enhanced XRT circle (D’Elia et al., GCN #28626; Perri et al., GCN #28638) we marginally detected the GRB OT (Pozanenko et al., GCN #28628; de Ugarte Postigo et al., GCN #28650; Dichiara et al., GCN #28654; Zhu et al., GCN #28655) with the brightness of R = 24.0 +/- 0.3 (calibrated against the nearby SDSS stars, magnitudes converted with the Lupton 2005 equations). We also obtained 12 x 300 sec. images in Rc band on October 16, 20:55:16--21:59:23, t_mid - T0 = 1.9435 days since trigger. We did not detect OT down to the limiting magnitude of R_lim = 24.0.
