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.
