dc.description.abstractIn this study, periods obtained from long-term multi-bands (Johnson V and R filters) photometric observations of some K, MandC spectral type semiregular (SR) variables obtainedw ith the T40 telescope (40 cm) andSSP 5A photometer at T¨UB˙I TAK National Observatory (TNO) between 1998 and 2005 were examined. We have found that some of these SR variables have multiple (long and short) periods as appearedm ostly from Hipparcos observations; three variables are, for the first time, observedt o have a period. The light curves, the variation amplitude in R band and the maximum light Epoch(s) of SR variables were also given. Besides, some difficulties encountered in the long-term observations were also discussed briefly.en_US
