Eight New Small Amplitude Variables We report the discovery of small amplitude variability of six cool starsand discuss the nature of their light change. Two unsolved variablesdetected by Hipparcos are discussed, too. Six stars of the sample belongto the SRVs, whereas in case of the other two objects variability ismost likely caused by a spotted surface.
