Scientific paper

The X-ray "Nova" Ophiuchi 1993, GRS 1716-249 (=GRO J1719-24), discovered in 1993 September, was redetected as an X-ray source by the Mir/Kvant team on 1995 February 16, and later by BATSE. Radio observations by the Molonglo Observatory Synthesis Telescope and the Very Large Array show a rapidly decaying radio flare followed by recurrent radio flaring activity. Although the X-ray flares, as seen at 20--200 keV by BATSE, are unusual in having sawtooth-like, slow-rise, fast-decay time profiles, the relation between X-ray and radio events is similar to that in the superluminal radio jet X-ray transient GRO J1655-40. This strengthens the apparent empirical link between changes in accretion disk X-ray emission and radio activity in galactic black hole binaries.
