Rapid changes in the light curve of the active, late-type subgiant CF Octantis.

INNIS J.L., COATES D.W. and KAYE T.G.

Abstract (from CDS):

B and V photometry of CF Octantis, obtained in 2006 July-2007 March, showed the spot-wave underwent a rapid change near HJD 2454040. The amplitude changed from 0.12 mag to less than half this. Such a rapid change has not been reported previously for this active subgiant.
