GSC 02004-00409 , the SIMBAD biblio

WW CVn (Right ascension: 13h34m30.9s, Declination: +29°18'15'') is an understudied RR Lyrae star which was found in the GEOS database. During 2 month in 2008, the star was studied using an CCD camera (ST10XME), a C11 and a photometric V filter. Six maxima have been observed and the full light curve determined. The amplitude of the light variation is smaller than given in GEOS, the period seems however not to have changed. Special is the double humped structure in the minimum of the light curve.
