Pandey (ARIES) report:\n\n\nWe observed the fast and red optical transient ZTF22aaajecp/AT2022cmc\ndiscovered with the Zwicky Transient Facility (Andreoni et al., GCN 31590)\nusing 1.3m Devasthal Fast Optical Telescope (DFOT) located at Devasthal\nobservatory of Aryabhatta Research Institute of Observational Sciences\n(ARIES), India. The observations were carried out at multiple epochs. Here,\nwe report our last night's observations, which started on 22-03 28\nat 19:32:05 UT~ 45.4 days after the first detection by the ZTF. We have\ntaken multiple frames having an exposure time of 120 sec in the R filter.\nWe stacked the images after the alignment. We detected ZTF22aaajecp/AT2022cmc\n(Andreoni et al., GCN 31590; Pankov et al., GCNs 31593, 31625, 31652, 31798;\nPerley, GCN 31594; Kumar et al., GCN 31597; Lipunov et al., GCN 31600; Tanvir\net al., GCN 31602; Lundquist et al., GCN 31612; Kann et al., GCN 31626; Yao\net al., GCN 31641; Freeburn et al., GCN 31647; and Cenko et al., GCN 31729) in\nour stacked image. The estimated preliminary magnitude is following:\n\nDate Start_UT T_start-T0 (days) Filter  Exp time (sec)       magnitude\n==============================================================\n2022-03-28 19:32   ~45.4           R        120 sec*60            22.04 +/-\n0.10\n\n\nThe magnitude is not corrected for the Galactic extinction in the direction\nof the burst.
