Abstract

We observed V404 Cyg with the Very Large Array Low Band Ionospheric and Transient Experiment (VLITE, http://vlite.nrao.edu ) at 341 MHz (38 MHz bandwidth) between 2015 June 17 10:52 UTC (MJD 57190.45) and June 25 12:17 UTC (MJD 57198.51). The upper limit on the flux density for the 3 min, June 17 observation is <= 20 mJy (3 sigma). The source was detected at 186 +- 6 mJy on June 22 from ~11:30 to 14:30 UTC (centered on MJD 57195.54) and at 90 +- 7 mJy on a 3 min, June 25 observation. For these measurements we have applied the flux scale of Scaife & Heald (2012). Finer resolution time and frequency analysis of our data are underway and will be reported if significant. These VLITE meter-wavelength data are bracketed by higher (ATEL #7716) and lower (ATEL #7720) frequency radio detections, helping constrain the broad-band, radio continuum spectrum and radio light curve. We note that the two VLITE detections bracketing the lower flux density LOFAR detection at 150 MHz may suggest a component of thermal absorption.
