\begintext

We present 59 new variable stars discovered by the Semi-Automatic
Variability Search sky survey (Niedzielski et al. 2003) operating
at the Astronomical Observatory of the Nicolaus Copernicus
University in Piwnice, near Toru\'n. 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\deg $\times$ 3 \deg wide)
covering 48 square degrees at the boundary of constellations of
Pegasus and Andromeda (23\hr27\mm30\sec$<\alpha<$23\hr56\mm30\sec
\ and +29\deg$<\delta<$+37\deg). About 9,600 stars brighter than
14.5 mag were observed in near-Johnson V band in total. The list of observed
fields, detailed hardware specification and description of data
reducing software as well as original data are available on
survey's web site {\tt http://www.astri.uni.torun.pl/\~{}gm/SAVS}.

The list of the new regular variable stars is presented in Table 1.
Their phased light curves in V band are shown in Figure 1. The
long-term variables are listed in Table 3 and their light curves
are displayed in Figures 2 and 3. The stars, for which
variability type cannot be resolved with our photometric data
(mostly long-term, red irregular or semi-regular variables), were
classified as ``miscellaneous'' and marked with MISC in Table 3. The
original photometric data are available from the survey's web site.

For several of the new variables, listed in Table 2, 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 {\AA} with 2 {\AA}/pix
reciprocal dispersion. These spectra, after standard reduction
performed with IRAF\footnote{IRAF is distributed by the National
Optical Astronomy Observatories, which are operated by the
Association of Universities for Research in Astronomy, Inc., under
cooperative agreement with the National Science Foundation.} were
used for spectral classification.

The  spectra used for spectral classification are presented in
Figures 4 and 5 for early and late spectral types star,
respectively. Most characteristic spectral features used for
classification are indicated.
