Abstract: Hinode has discovered a potential source of slow solar wind at the edges of active regions with the X-ray Telescope (XRT) and EUV Imaging spectrometer (EIS) on board Hinode e.g. Sakao et al. (2007), Harra et al. (2008), Doschek et al. (2008). These upflows are long-lasting and exist at the edges of most active regions. In this conference paper we first discuss the onset of the upflows. This is related to newly emerged magnetic flux into an active region. Next we discuss whether the flows that we see on the surface of the Sun actually are transported to the Earth in the slow solar wind. To do this we looked at a number of different examples over a Carrington rotation and tracked the response in the solar wind as measured by the ACE spacecraft at L1. We found that there is a significant enhancement of the in situ solar wind speed for active regions located close to a coronal hole.
