TITLE: GCN CIRCULAR NUMBER: 18363 SUBJECT: LIGO/Virgo G184098: ASKAP followup DATE: 15/09/24 21:07:32 GMT FROM: Keith Bannister at ATNF K. Bannister (CSIRO), J. Marvil (CSIRO), I. Heywood (CSIRO), R. Wark (CSIRO), M. Bell (CSIRO), T. Murphy (University of Sydney), D. Kaplan (UWM) on behalf of the ASKAP/VAST team We observed the Northern probability maximum with BETA - the ASKAP engineering test array. The observations cover a 9.5 x 9.5 degree square centered on 08h52m16s +06d32m00s with 8 pointings, each comprising 9 beams. We observed at center frequency of 863.5 MHz with a a bandwidth of 300 MHz. Observing began at 2015-09-21 20:40 UT and continued for 9 hrs. We expect a spatial resolution of around 165x45 arcseconds, and a detection limit of around 3 mJy. Progress on downloading, checking and processing these data has been slowed by scheduled maintenance at our primary computing facility. We will report on the result in the next few days. -- KEITH BANNISTER | Bolton Fellow CSIRO Astronomy and Space Science T +61 2 9372 4295 E keith.bannister@csiro.au
