Low-Speed Solar Winds Observed at Distances of 20-60 RS and Coronal Structure of their Source Regions
Abstract
The interplanetary scintillation (IPS) can probe the solar wind at distance and latitude range where in situ measurements have been impossible. Using the IPS method very low-speed (< 200 km/s) solar winds were observed at coronal active regions. Low-speed (~300 km/s) winds can be observed even around a polar coronal hole, and this winds is observed with a speed of 600 km/s at R > 60Rs.
