TITLE: GCN CIRCULAR NUMBER: 18477 SUBJECT: LIGO/Virgo G194575: ASKAP followup DATE: 15/10/27 02:42:50 GMT FROM: Keith Bannister at ATNF K. Bannister (CSIRO), J. Marvil (CSIRO), I. Heywood (CSIRO), R. Wark (CSIRO), B. Indermuehle (CSIRO), M. Bell (CSIRO), T. Murphy (University of Sydney), D. Kaplan (UWM) on behalf of the ASKAP/VAST team We observed the Southern probability maximum with BETA - the ASKAP engineering test array. The observations cover a 7x7 degree square centered on 13h02m00s -14d40m00s 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 2015-10-22 22:35:51 UT and continued for 10 hrs. Due to the proximity of the Sun, we expect worse than normal imaging fidelity. Analysis of these data are ongoing. -- KEITH BANNISTER | Bolton Fellow CSIRO Astronomy and Space Science T +61 2 9372 4295 E keith.bannister@csiro.au
