GCN Circular 20396
A. Corsi (TTU), M.M. Kasliwal (CalTech), D.A. Frail (NRAO), and N.T. Palliyaguru (TTU) report: We observed the position of the fast-fading ATLAS17aeu (Tonry et al. LVC GCN#20382) located in the error region of LIGO/Virgo G268556 (LVC GCN#20364) with the Karl G. Jansky Very Large Array (VLA) in its A configuration. The observations started on 2017-Jan-07 14:06:40 UT, ended on 2017-Jan-07 15:06:29 UT, and were carried out in C-band (central frequency of about 6 GHz). A provisional reduction of our data shows a radio source located at the position of ATLAS17aeu. For this source, we measure a radio flux of (159.0+/-9.8) uJy at 6.2 GHz. We note that the broad-band detection (radio, optical, and X-rays) of ATLAS17aeu is consistent with a GRB afterglow hypothesis (see Evans et al. LVC GCN#20390 and Kasliwal et al. LVC GCN#20393). Further observations are planned. We thank the VLA staff for rapidly executing these observations.
