Abstrakt

We present light curves of five short period variables of spectral type M. They are the first result of our monitoring program of LPVs with an automatic telescope. The stars vary semiregularly on time scales of about 35 days and with small visual amplitude. It is shown that the Fourier analysis is only of limited use for this kind of stars. We conclude that this type of variability is more common among M giants than previously thought, and we briefly discuss these variables with the shortest periods among the SRVs.
