Analysis of the solar coronal green line profiles reveals information regarding the physical conditions of the solar corona like temperature , density , Doppler velocity , non-thermal velocity etc .
It provides insights to the unresolved problems like the coronal heating and the acceleration of the solar winds .
Recent studies have reported excess blueshifts in the coronal line profiles and are interpreted as due to nanoflare heating , type II spicules and nascent solar wind flow .
We have analyzed a time series of Fabry-Perot interferograms of the solar corona obtained during the total solar eclipse of 2001 June 21 from Lusaka , Zambia .
The spatial behavior of the coronal green line profiles were examined and variations in intensity , linewidth , Doppler velocity and line asymmetry were obtained .
Several line profiles showed asymmetry indicating the presence of multicomponents .
Such line profiles were fitted with double Gaussian curves .
It has been found that 42 % of the line profiles were single components , 34 % were blueshifted , and 24 % were red shifted .
The secondary component of a typical line profile with blue asymmetry is found to have a relative intensity about 0.26 , Doppler velocity around -30 km/s and a halfwidth about 0.65 \AA .
