Comments:


1. MinII = 14.0. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

2. MinII = 14.6. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

3. MinII = 12.45. The star has a faint close companion 2MASS 02064073+3343231. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

Remarks:
I present the discovery of 33 new short-period (mostly EW) eclipsing binaries. 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.
