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 EP260530a (Wu et al.,
ATel #17824) on May 31 and again on Jun 02 UT. A set of clear
(roughly R) filter images were obtained. We clearly detected the
bright CV outburst associated with AT 2026nwl (TNS Astronomical
Transient Report 306622, 306654; TNS Classification Reports 23885;
Globus et al., GCN 44759). We measure its brightness decayed from
14.4 +/- 0.1 mag (Vega) at 0.98d after the burst, to 15.6 +/- 0.1
mag at 2.95d after the burst.
