We continued observations  optical transient of  ZTF22aaajecp/AT2022cmc 
  (Andreoni et al., GCN 31590) with AZT-33 telescope of Mondy 
observatory, Zeiss-1000 telescope of Tien Shan Astronomical Observatory, 
AS-32 telescope of Abastumani observatory. We detect the transient 
(Andreoni et al., GCN 31590; Kumar et al., GCN 31597; Pankov et al., 
GCNs 31593, 31625, 31652; Perley, GCN 31594; Lipunov et al., GCN 31600; 
Kann et al., GCN 31626; Yao et al., GCN 31641; Freeburn et al., GCN 
31647; Smith et al., GCN 31654; Dobie et al., GCN 31665; Sfaradi  et 
al., GCN 31667; Cenko et al., GCN 31729) at the redshift of z=1.193 
(Tanvir  et al., GCN 31602; Lundquist et al., GCN 31612).

Preliminary photometry of the transient observed in Mondy observatory on
