GCN Circular 34001
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 GRB 230618A detected by Swift (Page et al., GCN 33989) starting at 04:31:35 UT, about 0.69 hours after the bust. Observations were performed in the clear (roughly R) filter, and the exposure time was 60s per image, with a total of 31 images were obtained. We marginally detected the optical afterglow reported by Strausbaugh et al. (GCN 33992) in our coadd image in clear band, which we measured its brightness of 20.8 +/- 0.3 mag at a mid time of ~0.79 hours after the burst, calibrated to the Pan-STARRS1 catalog.
