report on behalf of GRB IKI FuN:
We observed the optical transient of ZTF22aaajecp/AT2022cmc (Andreoni
et al., GCN 31590) with AZT-33 telescope of Mondy observatory starting
on Feb. 24 (UT) 18:51:38. We detect the transient (Andreoni et al., GCN
31590; Kumar et al., GCN 31597; Pankov et al., GCNs 31593, 31625;
Perley, GCN 31594; Lipunov et al., GCN 31600; Kann et al., GCN 31626;
Yao et al., GCN 3164; Freeburn et al., GCN 31647) at the redshift of
z=1.193 (Tanvir et al., GCN 31602; Lundquist et al., GCN 31612).
Preliminary photometry of the transient is following
