TITLE: GCN CIRCULAR NUMBER: 35453 SUBJECT: GRB 240101A: KAIT Optical Upper Limit DATE: 24/01/02 07:21:22 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 240101A (Cenko et al.,
GCN 35448) starting at 15.57 hours after the burst. A total of
31x60s images were obtained in the clear (roughly R) filters.
We do not detect any optical afterglow candidate within the Enhanced
XRT position error circle (Beardmore et al., GCN 35452), neither in
single image, nor in the co-add images. The typical limiting magnitude
of our single clear image is about 18.5 mag calibrated to the PS1 catalog.
