Abstract
New UBVR photometry of FK Comae Berenices shows that the concentrated part of the spot distribution has shifted to a new active longitude, w hich is consistent with the recently defined ''flip-flop'' ephemeris f or a quarter of a century of photometry. The new ''flip-flop'' of FK C omae Berenices is the fourth one detected during 26.3 years.
