WEBJul 29, 2024 · The anticipated M9.3 coronal mass ejection has arrived at our planet. As expected, it looks like a glancing blow with the solar wind speed increasing to a modest 430km/s with the interplanetary magnetic field strength (Bt) increasing to about 15nT.
Sun news September 27: New sunspot region fires every flare
WEB2 days ago · A coronal mass ejection – blasted by the sun late yesterday – is on its way to Earth! Sunspot region AR3835 released an M3.8 flare at 21:39 UTC yesterday, and a huge column of solar plasma ...
Strong geomagnetic storm reaches Earth, continues through …
WEBMay 10, 2024 · NOAA space weather forecasters have observed at least seven coronal mass ejections (CMEs) from the sun, with impacts expected to arrive on Earth as early as midday Friday, May 10, and persist through Sunday, May 12, 2024.
G4 (Severe) Reached - NOAA / NWS Space Weather Prediction …
WEBBetween August 8-10, 2024, five Coronal Mass Ejections (CMEs) were observed leaving the Sun, prompting geomagnetic storm watches. The CMEs reached Earth over the weekend (August 11-12). CMEs, which are massive eruptions of solar material, can trigger geomagnetic storms upon arrival at Earth, potentially impacting various technologies.
Coronal Mass Ejections - NOAA / NWS Space Weather Prediction …
WEBCoronal Mass Ejections (CMEs) are large expulsions of plasma and magnetic field from the Sun’s 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.

How NASA Tracked the Most Intense Solar Storm in Decades
WEBDuring the first full week of May, a barrage of large solar flares and coronal mass ejections (CMEs) launched clouds of charged particles and magnetic fields toward Earth, creating the strongest solar storm to reach Earth in two decades — and possibly one of the strongest displays of auroras on record in the past 500 years.
