TITLE: GCN CIRCULAR NUMBER: 18345 SUBJECT: LIGO/Virgo G184098: MWA Followup DATE: 15/09/20 02:13:49 GMT FROM: David Kaplan at UW-Milwaukee D. Kaplan (UWM), S. Croft (UC Berkeley/Eureka Scientific), K. Bannister (CSIRO), T. Murphy (Sydney University), A. Rowlinson (UvA/Astron), S. Tingay (Curtin University), R. Wayth (Curtin University), T. Franzen (Curtin University), A. Williams (Curtin University) on behalf of the Murchison Widefield Array collaboration We observed three pointings designed to cover the majority of the skymap of the advanced LIGO/Virgo trigger G184098 with the Murchison Widefield Array radio telescope. The observations each cover roughly 30deg x 30deg (FWHM) centered at: 04:16:48 -63:06:00 2015-09-17 20:44 UT 08:08:00 -72:00:00 2015-09-18 00:36 UT 08:52:24 +01:54:00 2015-09-18 00:52 UT The observations are at a center frequency of 118 MHz, with a 30 MHz bandwidth. Each field was observed for a total of 12min, with 2s integrations and 10 kHz frequency resolution. These fields will be revisited starting on 2015-09-26. Analysis is ongoing.
