We observed the ZTF20acozryr/AT2020yxz (Coughlin et al., GCN 28841)
with AZT-20 telescope of Assy-Turgen observatory starting on Nov. 06
(UT) 19:10:28 in r'-filter. We detect the optical transient (Coughlin
et al., GCN 28841; Coughlin et al., GCN 28841; Xu et al., GCN 28846;
Xu et al., GCN 28854; Mao et al., GCN 28861; ) which can be afterglow
of GRB 201103B (Svinkin et al., GCN 28844; Evans et al., GCN 28858).
Preliminary photometry of the afterglow is following
