Pozanenko (IKI RAS), report on behalf of a larger\ncollaboration.\n\nWe observed the field of the fast red optical transient\nZTF23aaoohpy/AT2023lcr (Swain et al., GCN 34022) with the 1-m\ntelescope of SAO RAS Zeiss-1000/CCD-photometer on June, 22 and 23. We\nhave obtained 10 x 300 sec in Rc band during each night.\n\nThe OT (Swain et al., GCN 34022; Gompertz et al., GCN 34023; Kumar et\nal., GCN 34025; Adami et al., GCN 34030; Perley et al., GCN 34031;\nJiang et al., GCN 34040; Perley et al., GCN 34041; Fulton et al., GCN\n34042; Chen et al., GCN 34043, Belkin et al., GCN 34047; Breeveld, GCN\n34049; Leonini et al., GCN 34052; Moskvitin et al., GCN 34060, Belkin\net al., GCN 34077) is clearly detected in the stacked frames.\nPreliminary results are as following.\n\nDate        UT-start  MJD_mid      t-T0     R_mag\n2023-06-22  22:43:06  60117.96396  4.68865  21.68 +/- 0.14\n2023-06-23  21:14:21  60118.91196  5.63665  22.12 +/- 0.08\n\nPhotometry is based on stars mentioned in Belkin et al.(GCN 34047,\n34077) and Moskvitin et al. (GCN 34060). t-T0 is given in days after\nthe ZTF discovery (Swain et al., GCN 34022).\n\nThe light curve of the source has a shallow decay at least between\nMJD=60616 and MJD=60618, and then the decay becomes significantly\nsteeper between MJD=60618 and MJD=60619.\n\n",
