Comments:


1. High Amplitude Delta Scuti variable. J-H = 0.392 (2MASS). M-m = 0.4.

2. J-H = 0.177 (2MASS). M-m = 0.19. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

3. J-H = 0.253 (2MASS). M-m = 0.25:. Period 0.3799 d and type RRC are not excluded.

Remarks:
I present the discovery of 3 new short-period pulsating 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 from the 2MASS catalog.
