report on behalf of GRB IKI FuN:
We continued observations of the ZTF20acozryr/AT2020yxz (Coughlin et
al., GCN 28841) with AZT-33IK telescope of Mondy observatory. We
detect the optical transient (Coughlin et al., GCN 28841; Xu et al.,
GCN 28846; Zhu et al., GCN 28854; Mao et al., GCN 28861; Belkin et al.,
GCNs 28862, 28875; Mao et al., GCN 28863; Kumar et al., GCN 28876;
SungHak et al., GCN 28880) at redshift z = 1.105 (Xu et al., GCN
28847) associated with afterglow of GRB 201103B (Ursi et al., GCN 28831;
Svinkin et al., GCN 28844; Evans et al., GCN 28858).
Preliminary photometry of the afterglow is following
