TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5584 SUBJECT: GRB 060923: KAIT observations DATE: 06/09/23 06:07:28 GMT FROM: Weidong Li at UC Berkeley KAIT/LOSS W. Li, N. Butler, J. S. Bloom, and A. V. Filippenko, University of California, Berkeley, on behalf of the KAIT GRB team, report: The robotic 0.76-m Katzman Automatic Imaging Telescope (KAIT) at Lick Observatory observed GRB 060923, detected with Swift (Trigger 230662; Stamatikos et al. GCN 5583). The automatic sequence started at 05:12:33, 18 s after the burst. The first two images, however, failed due to some technical issues. In subsequent images, Our image processing pipeline did not find any new objects, and reported the following photometry limits (calibrated with USNO B1.0): ====================================================================== Start UT t(GRB) Filter Exp(s) 3sigma-limit 05:13:57 102s I 15.0 <16.9 05:14:21 126s clear 20.0 <17.9 05:14:52 157s V 45.0 <16.9 05:15:48 213s I 45.0 <17.5 05:16:43 268s clear 45.0 <18.5 05:17:39 324s V 60.0 <17.2 ======================================================================== More analyses are in progress.
