   Observations of the quiescent state of x-ray transients in the x-ray
   band are important for understanding the nature of the accretion flow
   in black hole candidate and neutron star systems. Here we propose to
   observe the quiescent state of one of the brightest x-ray transients,
   GRS1716-249. Our primary observational objective is to measure the
   quiescent flux and spectrum, or in the absence of a detection, to set a
   stringent new upper limit on the quiescent flux. In the context of the
   advection dominated accretion model, a measurement of the ratio of the
   quiescent luminosity to the peak outburst luminosity, provides
   information about the nature of the compact object, or alternatively
   can be used as a test of the model. If detected, the source spectrum
   will also provide useful information.
