ZTF21aayokph (AT2021lfa): Mondy and Koshka observatory optical observations
Abstract
We observed the field of ZTF21aayokph (AT2021lfa) (Yao et al., GCN 29938) with AZT-33IK telescope of Sayan observatory (Mondy) and and Zeiss-1000 telescope of Koshka observatory (INASAN). We clearly detect the optical transient (Yao et al., GCN 29938; Watson et al., GCN 29940; Butler et al., GCN 29941; Yao et al., GCN 29945; Fu et al., GCN 29948; Kim et al., GCN 29950; O'Connor et al., GCN 29952) in Mondy observatory and marginally detect it in Koshka observatory. Preliminary photometry of the optical transient is following Date UT start Filter Exp. OT Err.
