New CCD Photometry Study of RV UMa
  All available CCD observation of RV UMa have been analyzed to obtain an
accurate mathematical description of the ligh variation. We discuss in this
paper a new study of variable star RV UMa, a short period RRab star, in orther
to determine through the light curve and the physical parameters, the presence
of "Blazhko effect". The Star were observed for a total of 839 sessions
shooting, and exhibits light curve modulation with the shortest modulation
Period=0.468002 ever observed. The result detect small but definite
modification in temperature and mean radius of the star itself. All results are
compared with previously published literature values and discussed.
