High resolution echelle spectra of PW And ( HD 1405 ) have been taken during eight observing runs from 1999 to 2002 .
The detailed analysis of the spectra allow us to determine its spectral type ( K2V ) , mean heliocentric radial velocity ( V _ { hel } = -11.15 km s ^ { -1 } ) rotational velocity ( v \sin { i } = 22.6 km s ^ { -1 } ) , and equivalent width of the lithium line \lambda 6707.8 { \AA } ( EW ( Li I ) = 273 mÅ ) .
The kinematic ( Galactic Velocity ( U , V , W ) ) confirms its membership of the Local Association moving group , in agreement with the age ( 30 to 80 Myrs ) inferred from the color magnitude diagram and the lithium equivalent width .
Photospheric activity ( presence of cool spots that disturb the profiles of the photospheric lines ) has been detected as changes in the the bisectors of the cross correlation function ( CCF ) resulting of cross-correlate the spectra of PW And with the spectrum of a non active star of similar spectral type .
These variations of the CCF bisectors are related to the variations in the measured radial velocities and are modulated with a period similar to the photometric period of the star .
At the same time , chromospheric activity has been analyzed , using the spectral subtraction technique and simultaneous spectroscopic observations of the H \alpha , H \beta , Na i D _ { 1 } 
and D _ { 2 } , He i D _ { 3 } , Mg i b triplet , Ca ii H & K , and Ca ii infrared triplet lines .
A flare was observed during the last observing run of 2001 , showing an enhancement in the observed chromospheric lines .
A less powerful flare was observed on 2002 August 23 .
The variations of the chromospheric activity indicators seem to be related to the photospheric activity .
A correlation between radial velocity , changes in the CCF bisectors and equivalent width of different chromospheric lines is observed with a different behaviour between epochs 1999 , 2001 and 2002 .
