GRB 200524A: KAIT Optical Observations
Abstract
The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, observed the field of GRB 200524A (Fermi-LAT detection: Dirirsa et al., GCN 27797; Fermi GBM detection: Pookalil et al., GCN 27809), starting at ~1.08 days after the burst. We obtained 24x60s images in the clear (roughly R) filter. We detect the optical afterglow at the location of ZTF20abbiixp/AT2020krl (Ho et al., GCN 27799) in our co-added image. We estimate the afterglow, which was also reported by other groups (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), to be 21.2 +/- 0.2 magnitude in clear filter, calibrated to PS1 catalog.
