Abstract

Visual observations made by experienced observers are adjusted for individual observer bias. We examine the time series using signal processing methods to identify periodicities and test for the significance of the results finding a reliable periods in S Per, and to a limited extent in RS, SU, BU, and KK Per. Recommendations for future visual and electronic observation are made.
