Description:
A program of (UBVRI)c photometric observations of twelve southern
hemisphere Long Period Variables (LPV or Miras) has been carried out
at the European Southern Observatory. Each star was observed on at
least 11 occasions up to 29 over a 4-year period. A determination of
their spectral types and their distance was also performed. We
therefore present for the first time spectral type variations together
with visible and colour light-curves for at least three successive
cycles.
