The authors report on observations of the X-ray binary V1727 Cygni, which ordinarily displays a pronounced X-ray heating light curve on a 5.2 hr period, taken when the object was in an X-ray and optical low state. Extensive CCD photometry obtained at McGraw-Hill Observatory shows no photometric modulation. No eclipse is detected, despite extensive coverage at the expected phase in both the V and B photometric bands. The authors describe attempts to reconcile these observations with previous models of this supposedly well-characterized system, which predict that the low state should exhibit strong ellipsoidal variations or eclipses or both.
