Geocoronal Solar Wind Charge Exchange Process Associated with the 2006-December-13 Coronal Mass Ejection Event
Yu Zhou, Noriko Y. Yamasaki, Shin Toriumi +1
We report the discovery of a geocoronal solar wind charge exchange (SWCX) event corresponding to the well-known 2006 December 13th coronal mass ejection (CME) event. Strong evidenc…
