Our time series analysis of sixteen BV
light curves of the chromospherically active binary V511 Lyr confirmed
the 
rotation period uniquely.
The seasonal periodicity changes of 3.8% indicated
the presence of detectable surface differential rotation.
The significant 
periodicity in
the light curve minimum epochs suggested that
the strongest starspot formation in V511 Lyr was concentrated
on one stable active longitude.
Key words: stars: individual: V511 Lyr (HDE 337518) / stars: variable: general / stars: activity / techniques: photometric
