TITLE: GCN CIRCULAR NUMBER: 19151 SUBJECT: GRB 160303A: JCMT SCUBA-2 sub-mm observation DATE: 16/03/05 17:59:00 GMT FROM: Ian Smith at Rice U I.A. Smith (Rice U.), N.R. Tanvir (U. of Leicester), and Y. Urata (NCU) report: We observed the location of the possibly short GRB 160303A (Beardmore et al., GCN Circ. 19126) using the SCUBA-2 sub-millimeter continuum camera on the James Clerk Maxwell Telescope. The observation started at 11:56 UT on 2016-03-03, corresponding to 62 minutes after the burst trigger. Exposures totaling 2.0 hours were made in good weather conditions. No source was detected, with the RMS background noise being 1.4 mJy/beam at 850 microns and 14.8 mJy/beam at 450 microns. We thank Callie Matulonis and Iain Coulson for the prompt support of these observations that were taken under project M16AP005.
