Abstract

(Abstract only) Frequent random visual observations of six eclipsing binaries with no published minima within the past three decades have been made with the objective of establishing normal times of minima for the observing season. Well-defined light curves were obtained for five of these stars, BQ Aqr, DD Her, GU Her, LV Her, and V345 Cyg. The sixth star, NQ Her, although well-observed at all phases of the eclipse cycle, shows no evidence of a visually detectable eclipse.
