TITLE: GCN CIRCULAR NUMBER: 17626 SUBJECT: GRB 150323A: KAIT Optical Observations DATE: 15/03/23 21:09:12 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 150323A (Amaral-Rogers et al., GCN 17611) starting at 03:23:43 UT, ~34 minutes after the burst. 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 Cenko & Perley (GCN 17612) was not detected in any single image, but was marginally detected in the co-add image of 20 clear band images. We estimated the brightness is R~20.3 +/- 0.3 at a mean time of 71.2 minutes after the burst.
