Abstract

 

The light curve of this nova-like star displays three types of variation: (1) Brightening of up to three magnitudes associated with the ejection of hot gas from either or both components of the close binary, (2) eclipses whose shapes vary from cycle to cycle, (3) irregular and very rapid fluctions, called "flickering." This flickering was observed visually on several nights in October, 1978, when the star appeared to change brightness by up to 0.6 mag. in several seconds.
