The CME that was fired on May 7 hit Earth as expected late last night, bringing a G1 geomagnetic storm. Forecasts suggest that this will increase to a G2 storm later today, so get ready, aurora-watchers! Meanwhile, activity on the sun remains high - AR3296 released two M flares over the past day, one of which produced a full halo CME and a rare solar particle burst. Having just developed a delta region, flaring potential for this sunspot continues to grow - stay tuned for more action! Get all th

A coronal mass ejection (CME) is on its way to Earth! It came from a filament eruption, which blasted a great burp of solar material into space yesterday. Specialists estimate the CME will reach Earth by tomorrow afternoon, likely bringing G1 (minor) or G2 (moderate) disturbance to Earth's magnetic field. Get ready for more auroras! https://earthsky.org/sun/sun-activity-solar-flare-cme-aurora-updates/ 📸 via NOAA | EarthSky
