Here’s a Coronal Mass Ejection Right Before It Hit Earth
Coronal Mass Ejections (CMEs) are large expulsions of plasma and magnetic field from the Suns corona. They can eject billions of tons of coronal material and carry an embedded magnetic field (frozen in flux) that is stronger than the background solar wind interplanetary magnetic field (IMF) strength. CMEs … Zobacz więcej The more explosive CMEs generally begin when highly twisted magnetic field structures (flux ropes) contained in the Suns lower corona become too stressed and realign into … Zobacz więcej Important CME parameters used in analysis are size, speed, and direction. These properties are inferred from orbital satellites coronagraph imagery by SWPC forecasters to determine any Earth-impact likelihood. The … Zobacz więcej Important aspects of an arriving CME and its likelihood for causing more intense geomagnetic storming include the strength and direction of the IMF beginning with shock arrival, followed by arrival and passage of the … Zobacz więcej Imminent CME arrival is first observed by the Deep Space Climate Observatory (DSCOVR) satellite, located at the L1 orbital area.
