TITLE: GCN CIRCULAR NUMBER: 43468 SUBJECT: EP260119a: KAIT optical observations DATE: 26/01/20 08:08:36 GMT FROM: Weikang Zheng at UC Berkeley <weikang@berkeley.edu> WeiKang Zheng (UCB), Xuhui Han (NAOC), Pinpin Zhang (NAOC) and Alexei V. Filippenko (UCB) report on behalf of the KAIT GRB team: The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, observed the field of EP260119a (Jiang et al., GCN 43447; Cheng et al., GCN 43449; Jiang et al., GCN 43465) from 8.13 to 11.55 hours after the burst. A set of 150x60s clear (roughly R) filter images were obtained. We clearly detected the optical afterglow (Fortin et al., GCN 43450; Eyles-Ferris et al., GCN 43452; Lipunov et al., GCN 43454; Fortin et al., GCN 43455; Moskvitin & Spiridonova, GCN 43463; Liu et al., GCN 43464; Ma et al., GCN 43466) in our coadd image. We measure its brightness to be 21.6 +/- 0.2 mag (Vega) at a mid time of 9.84 hours after the burst.
