![]() ![]() Slower CMEs can take several days to arrive. At a time in the suns cycle when space weather experts expect less solar activity, our star is going bonkers with solar flares and coronal mass ejections. The fastest Earth-directed CMEs can reach our planet in as little as 15-18 hours. ![]() “CMEs travel outward from the Sun at speeds ranging from slower than 250 kilometers per second (km/s) to as fast as near 3000 km/s. ![]() National Oceanic and Atmospheric Administration (NOAA) explains how CMEs or coronal mass ejections can take between as little as 15-18 hours and up to several days to arrive on Earth. Explaining what Coronal Mass Ejections (CMEs) are, NOAA said these are “large expulsions of plasma and magnetic field from the Sun’s corona” that 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.” ![]()
