TITLE: GCN CIRCULAR NUMBER: 19242 SUBJECT: GRB 160327A: KAIT optical afterglow confirmation DATE: 16/03/28 19:36:40 GMT FROM: Weikang Zheng at UC Berkeley 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 [GCN OPS NOTE(30mar16): Per author's request, the second reference was changed from Zach to Golkhou.]
