Comments:


1. M-m = 0.45 P, b = -1.1 deg.

2. M-m = 0.33 P, b = -1.8 deg.

3. M-m = 0.5: P, b = +2.0 deg., B-V = 1.72

Remarks:
We present the discovery of 3 new Ñepheid (DCEP and DCEPS) variables. A search for variables was carried out in the publicly available data of the Northern Sky Variability Survey (NSVS, Wozniak et al., 2004, also see http://skydot.lanl.gov/nsvs). These observations were analyzed using the period-search software developed by Dr. V.P. Goranskij for Windows environment. The coordinates were drawn either from the Tycho-2 or 2MASS catalogs.
