TITLE: GCN CIRCULAR NUMBER: 37656 SUBJECT: EP240930a : KAIT optical upper limit DATE: 24/10/01 18:06:52 GMT FROM: Weikang Zheng at UC Berkeley weikang@berkeley.edu
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, responded to EP240930a (Tian et al., GCN 37648)
starting at 05:04 UT, Oct 1st, ~11.8 hours after the trigger. A
set of 30x60s images were obtained in the clear (roughly R) filters.
Preliminary analysis do not reveal any new optical counterpart
candidate within the EP-FXT source error circle (Peng et al., GCN
37653) neither in single image, nor in the co-add images. The typical
limiting magnitude of our single clear image is about 19.5 mag, and
about 20.5 mag in the co-add image.
