TITLE: GCN CIRCULAR NUMBER: 18655 SUBJECT: LIGO/Virgo G184098: Results of of 2nd epoch of ASKAP follow-up DATE: 15/12/02 12:42:58 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), S. Chatterjee (Cornell) on behalf of the ASKAP/VAST team. We observed the Southern probability maximum with BETA - the ASKAP engineering test array. The observations comprise 18 pointings covering a strip approximately 40 degrees long and 5 degrees high, centered on 07h27m51s -70d15m39s (J2000) and following the ridge of the probability maximum. We observed at center frequency of 863.5 MHz with a a bandwidth of 300 MHz. Observing began at 2015-09-26 13:15:00 UT and continued for 19.5 hrs. Our images have an average RMS of 1 mJy/beam. We cross matched all sources from our images with the SUMSS and MGPS2 catalogs, which are complete above 14 mJy. We found 3 sources not in the catalog, but visual inspection of the SUMSS [1] and MPGS2 [2] images indicates the presence of a source in all cases. Thus, we detect no transients above 14 mJy with respect to those surveys. We continue to process another earlier observation of the same field.
