Activity in late-type dwarfs. II. Flares and SPOT variations on GL 867A (=FK Aqr) in 1981.
Abstract
We present optical photometry of flares and spot variations on the flare/BY Draconis star G1 867A (= FK Aqr). Time-integrated rates of energy lost by optical flaring are derived and compared with previously published results. No evidence of season-to-season changes are evident. No spot variations were detected but there is an unusually large scatter in the mean light curve.
