Comments:


1. MinII = 13.7. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

2. MinII = 14.6. Type RRC (with twice shorter period) is possible. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

3. MinII = 12.08. A twice shorter period and type RRC are not excluded.

4. MinII = 14.2. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

Remarks:
I present the discovery of 51 new short-period eclipsing binaries (mostly EW). 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.
