TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1487 SUBJECT: Millimeter observation of GRB 020813 DATE: 02/08/14 13:08:04 GMT FROM: Michael Bremer at IRAM Grenoble Millimeter observations of GRB 020813 ====================================== The burst has been observed with the IRAM Plateau de Bure Interferometer in a five-antenna compact configuration from August 13, 21:13 UT to August 14, 00:58 UT under good meteorological conditions, on the position given in GCN 1474 : (EQ 2000) 19:46:41.865 -19:36:04.76 . The source was not detected. Results of UV plane fits fixed on the phase center: Frequency Flux and 1 sigma error Beam size ---------------------------------------------------------------------- 89.188 GHz : -0.13 (+-0.37) mJy/beam 15.6" by 6.5" at PA -158 deg 232.032 GHz : -0.63 (+-2.06) mJy/beam 6.5" by 2.6" at PA 27 deg No other source was detected above the 3 sigma level within the half-power width of the primary beams (55.5" at 89.188 GHz and 31.3" at 232.032 GHz).
