Abstract
This work summarizes the results of photographic photometry obtained over 2 4 years at the Skalnate Pleso (1979-1993) and Asiago (1969-1988) observator ies. The period of light changes, the epoch of the maximum or of the minimu m, the type of variability and, in some cases, possible causes of the long- term behaviour of light changes were determined for 17 variable stars.
