A possible secondary minimum of the long-period eclipsing binary OW Gem (NSV 3005).

WILLIAMS D.B.

Abstract (from CDS):

Photoelectric photometry of the 1258-day eclipsing binary OW Gem = NSV 3005 during the 1988-89 season found the star constant at maximum except for the interval JD 2447531-540, when it was almost 0.1 magnitude fainter. If the observed event was the secondary eclipse, the unseen companion is a large cool star, probably a late-G to early-M giant, and the orbit of the binary system is highly eccentric with secondary minimum occurring at phase 0.23 of the photometric period
