Enhanced Radio Activity in the Quiescent State of the X-ray Transient V404 Cyg (=GS2023+338)

The quiescent state of the X-ray transient and 14 solar mass black hole binary, V404 Cyg (=GS2023+338), since it ended the long decay that accompanied its initial discovery event at X-ray, optical, and radio wavelengths (Han and Hjellming, Ap.J., 400, 304, 1992), has been associated with a 0.4 mJy radio source and, most of the time, a 7 microJy X-ray source at 2-12 keV (1 ASM count/sec = 24 microJy) in the RXTE ASM daily averages.
