Harra et al.2008: Hinode/EIS coronal outflows from active regions with V~ 50 km/s
Sakao et al. 2007: 20-22 February 2007 HINODE/XRT observed outflows from edges of AR with V=100-170 km/s

HINODE/EIS observations of AR 11112 on October 15, 2010
4. Case study of AR 11112 on October 15 -21, 2010
SWAP/PFSS October 21
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
