Webb9 sep. 2024 · A search for extremely slow ( Vsw < 300 km s −1) solar winds (ESSWs) at 1 au has been conducted using hourly average solar wind data from 1963 through 2024. 297 ESSW events were identified with an average duration of ∼2.0 ± 1.4 days. The lowest speed detected was 156 km s −1. Ten of the lowest-speed events were analyzed in detail. Webb7 jan. 1998 · A theory for the origin of the slow solar wind is described. Recent papers have demonstrated that magnetic flux moves across coronal holes as a result of the interplay … Webb6 jan. 2015 · While the fast wind is known to emanate primarily from polar coronal holes, the source of the slow wind remains unknown. Here we identify possible sites of origin using a slow solar wind source map of the entire Sun, which we construct from specially designed, full-disk observations from the Hinode satellite, and a magnetic field model. how to start getting experience in agile
