摘要：
This work summarizes the results of photographic photometry obtained over 24 years at the Skalnate Pleso (1979-1993) and Asiago (1969-1988) observatories. The period of light changes, the epoch of the maximum or of the minimum, the type of variability and, in some cases, possible causes of the long-term behaviour of light changes were determined for 17 variable stars.
