Eighteen New Variable Stars in Cassiopeia and Variability Checking for NSV 364

I report the discovery of eighteen new variable stars in Cassiopeia: eight pulsating (2MASS J00584964+5909260; GSC 03680-00667; GSC 03680-01320; GSC 03680-01488; 2MASS J02472793+6149024; GSC 04047-01118; GSC 04047-01418; GSC 04051-01789), six eclipsing (GSC 03680-00423; 2MASS J02443720+6143091; GSC 04047-00381; GSC 04047-00558; GSC 04051-02027; GSC 04051-02533), three rotating (ALS 6430; 2MASS J01020513+5912394; GSC 04051-01669), and one eruptive (GSC 04051-02483). The suspected variable star NSV 364 was checked for variability in six nights of observations and in the complete SuperWasp survey dataset: no variability was detected.
