Summary of the first results1. Outflows detected by Doppler shifted spectral lines are

accompanied by coronal signatures - fan rays at the disk and extended coronal rays (R>1.5 Rsun) at the limb

2. Fan rays and coronal rays represent different views of the same coronal structure co-aligned with open magnetic field lines

3. Middle term variations (hours) of the slow solar wind flux are correlated with latitudinal distribution of the integrated outflow flux in the AR.

Studies of the solar wind sources and their modeling will be continued in new eHEROES project
