Discovery of an SU UMa-type eclipsing cataclysmic variable star inside the CV ``period gap''.

CAGAS P. and CAGAS P.

Abstract (from CDS):

We report the discovery of CzeV404 – eclipsing SU UMa-type cataclysmic variable star with an orbital period inside the period gap. Using photometric observations taken during 15 nights from June to September 2012 and 8 nights from July to August 2013 we determined an orbital period of 2.35 hours and superhump period of 2.50 hours. From the observed period excess, the estimated mass ratio of the system is q = 0.30.
