  The "U,B,V,R,I" light curves of the type IIP supernovae (SNe IIP)
  SN 2005ay and SN 2005cs, and one spectrum for SN 2005cs, are presented and
analyzed. We found both events to be fainter than the average SN IIP, with SN
2005cs showing slight brightening in the second half of plateau stage in the
  $V,R,I$ bands and a low expansion velocity.
  The effects of two different plausible distance moduli on the derived
physical parameters of SN 2005ay are considered.
  Two approaches are used to estimate the expansion velocities at the middle of
the plateau phase. Based on empirical analytical models we derived constraints
on the progenitor properties. The amounts of the ejected $^{56}$Ni are also
recovered.
