Abstract

The article we published earlier on this star (Baldwin et al. 1976) requires major revision and correction. Following our announcement of the extraordinarily large change of period in this eclipsing binary we looked forward to the arrival of the next observing season and collection of additional visual data for further refinement oftheperiod. However, when the first minima of the season were obtained they failed to confirm the new ephemeris. Minima continued to occur more than six hours early as compared to elements by Kukarkin et al. (1976)
