Abstract
ABSTRACT Photometric observations of the massive spectroscopic binary system HD 217312 have been obtained. These observations, together with more recent observations by Rao, indicate that HD 217312 undergoes a shallow eclipse. The time of the eclipse is in good agreement with the time predicted by the spectroscopic orbital elements. Key words: photometry - spectroscopic binary systems
