TITLE: GCN CIRCULAR NUMBER: 25690 SUBJECT: LIGO/Virgo S190814bv: VLA/JAGWAR monitoring of the 50% containment region DATE: 19/09/09 23:54:35 GMT FROM: Kunal Mooley at NRAO,Caltech Kunal Mooley (NRAO, Caltech; Jansky Fellow), Steve Myers, Dale Frail (NRAO), Gregg Hallinan, Shri Kulkarni (Caltech), Alessandra Corsi, Arvind Balasubramanian, Deven Bhakta (TTU) report on behalf of the JAGWAR team We have initiated deep L band (1-2 GHz) multi-epoch observations of the 50% containment region (5 sq deg; GCN 25333) of the GW event S190814bv with the Karl G. Jansky Very Large Array. A total of 28 pointings (coordinates given below), observed as part of the JAGWAR program, will achieve a uniform RMS noise between 10-15 uJy over the 5 sq deg region. Additional pointings to cover cataloged high-mass and high-SFR galaxies are planned, and will be announced later. We will report any radio transients found through the GCN system. Observations of this region with other telescopes is encouraged.
