We present 59 new variable stars discovered by the Semi-Automatic Variability Search sky survey. Photometric data were collected with the semi-automatic telescope equipped with a 135/2.8 telephoto lens and SBIG ST-7XE CCD camera with KAF-0402ME chip. Observations were collected between September and December 2004 while monitoring 8 fields (each 2 x 3 deg wide) covering 48 square degrees at the boundary of constellations of Pegasus and Andromeda (see Monitored Fields for details). About 9,600 stars brighter than 14.5 mag were observed in near-Johnson V band in total.

Light curves of the new regular variable stars are shown in figures below.

For several of the new variables additional spectral observations were performed with the 0.9m Schmidt-Cassegrain telescope equipped with the Richardson spectrograph and a Wright CCD camera. Using the 600 gr/mm grating we obtained spectra between 3800 and 5800 A with 2 A/pix reciprocal dispersion. These spectra, after standard reduction performed with IRAF were used for spectral classification.

Full results are presented in the published paper IBVS5614.
