Photoelectric Photometry of OW Geminorum at Phase 0.5 Differential V photometry of the 3.45-year eclipsing binary OW Gem nearphase 0.5 shows no indication of a secondary minimum. This resultsupports the earlier conclusion that OW Gem is a highly eccentric binarysystem with secondary minimum occuring at phase 0.23.
A Possible Secondary Minimum of the Long Period Eclipsing Binary OW Gem (NSV 3005) Photoelectric photometry of the 1258-day eclipsing binary OW Gem = NSV3005 during the 1988-89 season found the star constant at maximum exceptfor the interval JD 2447531-540, when it was almost 0.1 magnitudefainter. If the observed event was the secondary eclipse, the unseencompanion is a large cool star, probably a late-G to early-M giant, andthe orbit of the binary system is highly eccentric with secondaryminimum occurring at phase 0.23 of the photometric period.
