TITLE: GCN CIRCULAR NUMBER: 36939 SUBJECT: GRB 240727A: KAIT Optical Afterglow Candidate DATE: 24/07/27 04:49:46 GMT FROM: Weikang Zheng at UC Berkeley <weikang@berkeley.edu> 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.
