Eclipsing Binaries: Ccd Images

Scientific paper

PG 1550+ 131 was known as a faint, very blue object (V = 16.8, U-B =-1.2) in the constellation Ophiuchus. Its optical Spectrum showed the Balmer lines and the Balmer jump in emission. Scarce Photometric data indicated large amPlitude variations. So it seemed to be a relatively uninteresting member of the cataclysmic variables, not deserving further detailed observational attention. Nevertheless, it was included in a programme to search for eclipsing, faint Cataclysmic variables and aiming at the determination of primary masses in such systems. The observations were performed using the CCD camera at the Oanish 1.5-m telescope at La Silla. PG 1550+ 131 turned then out to be the most spectacular eclipsing system found during this survey.
