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 151027A (Racusin et al.,
GCN 19235) starting at 09:17:37 UT, 90 s after the burst under
fair condition. Observations were performed with an automatic
sequence in the clear (roughly R), V, and I filters, and the
exposure time was 20 s per image.
The afterglow reported by Golkhou et al. (GCN 19236) was not detected
in any of our single images, however, it is detected in the
co-added images in both clear and I band, except V band. We report
the follow detection magnitude or upper limit:
Filter co-add Mid-time Detection_Mag Upper_limit
clear 20s x 10 549s 19.8 +/- 0.3 -
clear 20s x 10 1495s 20.2 +/- 0.4 -
clear 20s x 10 2162s - 20.0
I 20s x 10 615s 18.1 +/- 0.2 -
I 20s x 10 1541s 18.8 +/- 0.4 -
I 20s x 10 2195s - 18.7
V 20s x 15 781s - 18.9
