M5 V101 - A close binary system in a globular clusterSpectrophotometric and photographic observations of the large amplitude variable V101 in the globular cluster M5 show it to have the characteristics of a dwarf nova. In particular, a spectrum obtained with the Hale 5 m reflector of the object in quiescence (V approximately equal to 20) shows strong, broad Balmer and He I emission. It is suggested that M5 V101 is the strongest case for the existence of close binary systems in globular clusters.
