Scientific paper

The massive eclipsing system NY Cephei has been observed photometrically for several years. A new time of primary minimum at JD(Hel.)2442682.867 + or - 0.006 yields a period for the system of 15.2756 + or - 0.0001 days. An unsuccessful search for a secondary eclipse suggests that such an eclipse does not occur and this provides an upper limit to the system's inclination. The depth of primary eclipse is close to 0.13 mag in U, B, and V. The components are thus very similar in color, as they are in spectral type, despite their unequal masses.
