  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
