TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2088 SUBJECT: GRB 030329: Sub-millimeter detection DATE: 03/04/04 04:33:29 GMT FROM: Ian Smith at Rice U Jim C. Hoge (JCMT), Rowin Meijerink (Leiden Observatory), Remo P.J. Tilanus (JCMT), and Ian A. Smith (Rice University) report on behalf of the NL JCMT collaboration: We have observed the afterglow of GRB 030329 (GCN 1985 and following) using the SCUBA sub-millimeter continuum bolometer array on the James Clerk Maxwell Telescope located on Mauna Kea, Hawaii. The observations took place on 2003 Apr 03.4 UT. Although the conditions were not very good, the source was easily detected. Preliminary calibration gives an 850 micron flux density of 30 +/- 5 mJy. Further observations are planned.
