We present optical observations of the active M dwarf EY Dra.
Longitudinal location of the starspots on the stellar surface is
deduced from the V band photometry and these locations are then
correlated with the chromospheric structures that are obtained from
the simultaneous spectroscopic H alpha observations.  The photometric
observations show a clear W-shaped minimum which corresponds well with
the enhanced emission in the H alpha.
