GRB 200524A: Kitab observatory afterglow observations
Abstract
We observed Fermi-LAT detected localization area of GRB 200524A (Dirirsa et al., GCN 27797; see also Pookalil et al., GCN 27809; Capalbi et al., GCN 27811; Gupta et al., GCN 27818) with Kitab-ISON RC-36 telescope starting on 2020-05-24 (UT) 19:07:41. In a stacked image in Clear filter (CR) we marginally detected optical afterglow discovered by ZTF (Ho et al., GCN 27799) and confirmed by several observations (Kumar et al. GCN 27800; (Kumar et al., GCN 27800; Rumyantsev et al., GCN 27802; Sanwal et al., GCN 27803; Perley et al., GCN 27805; Kumar et al., GCN 27806; de Ugarte Postigo et al., GCN 27807; Blazek et al., GCN 27810; Ogawa et al., GCN 27813; Izzo, GCN 27817). Preliminary photometry is following Date, UT start, t-T0, Exp., Filter, OT, Err., UL (mid, days) 2020-05-24 19:07:41 0.60673 60*60 CR 20.48 0.25 21.0 The photometry is based on nearby USNO-B1.0 stars USNO-B1.0_id R2 1508-0206198 15.78 1509-0204466 16.48 1509-0204434 16.53
