Letter Re: Coronal Mass Ejections and Their Consequences
Good Morning James, The recent coronal mass ejection (CME) began interacting with the terrestrial magnetosphere earlier today. Though initially that interaction was rather subdued a rapid fall-off in the proton particle counters is actually leading to some rather elevated readings over at the Rice.edu monitor site. Polar convection, density and velocity are all registering in the yellow band, while the Interplanetary Magnetic Field (IMF) magnitude, angle and the dynamic pressure are all passed up into the red zones. It is worth remembering that a CME consists of hot, charged particles (ionized hydrogen primarily) and as such the situation is similar …
