Global Distribution of the Solar Wind Flux and Velocity From SOHO/SWAN During SC-23 and SC-24
Schmidt, W.; Quémerais, E.; Koutroumpa, D. +1 more
We analyze SOHO (SOlar Heliospheric Observatory)/SWAN (Solar Wind ANisotropy) hydrogen Lyman-α data collected between 1996 and 2018 to derive the solar wind latitudinal distribution over time. Full-sky interplanetary Lyman-α maps are inverted to derive the total hydrogen ionization rate latitude profiles, normalized to proton charge-exchange and p…
Observations on a Series of Merging Magnetic Flux Ropes Within an Interplanetary Coronal Mass Ejection
Zhao, Yan; Feng, Hengqiang; Zhao, Guoqing +2 more
Coronal mass ejections (CMEs) are intense solar explosive eruptions. CMEs are highly important players in solar-terrestrial relationships, and they have important consequences for major geomagnetic storms and energetic particle events. It has been unclear how CMEs evolve when they propagate in the heliosphere. Here we report an interplanetary CME …
