WeiKang Zheng and Alexei V. Filippenko (UC Berkeley) report on
behalf of the KAIT GRB team:
The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at
Lick Observatory, responded to Swift GRB 240727A (Parsotan et al.,
GCN 36938) starting on July 27, 04:22:16 UT. We detected an uncataloged
optical afterglow candidate not shown in DSS archive at position
of (error ~0.5"):
RA: 15:45:44.98 (J2000)
Dec: +08:37:13.15 (J2000)
This position is about 1.1 arcsec to the Swift/XRT localization
(Parsotan et al., GCN 36938). We measure the target is ~19.0 in our
clear band image at ~34 minutes after burst. We can not estimate the
variability at this time, further observations are encouraged.
