Abstract:
    We have identified 23 RR Lyrae stars and three possible anomalous
    Cepheids (ACs) among 84 candidate variables in the recently discovered
    Canes Venatici I (CVn I) dwarf spheroidal galaxy.

Description:
    BV and Cousins I time-series photometry of CVn I was obtained in 2006
    May and 2007 April and May at the 2.3m Wyoming Infrared Observatory
    telescope (WIRO), using the prime focus CCD camera.
    Additional BVI photometry was obtained at the 4.2m William Herschel
    Telescope (WHT) in 2007 April using the Prime Focus Imaging Camera.

             1.5-2mag above the galaxy's horizontal branch)
