INTENSIFYING SOLAR ACTIVITY: By the time you finish reading this, the sun will have probably flared again. Earth-orbiting satellites are detecting an almost non-stop fusillade of M-class flares so closely-spaced they overlap in time:

GLANCING-BLOW CME: NOAA forecasters say that a CME might deliver a glancing blow to Earth's magnetic field on May 21st. It left the sun May 17th, propelled by an erupting filament of magnetism in the sun's southern hemisphere. The impact could produce minor G1-class geomagnetic storms.

A DANGEROUS SUNSPOT: Growing sunspot AR3311 has an unstable 'beta-gamma-delta' magnetic field that harbors energy for strong solar flares. NOAA forecasters say there is a 75% chance of M-class flares and a 35% chance of X-flares on May 21st.

Solar Activity Alert: Potential Flares Today

Get ready for potential solar fireworks as sunspot AR3311 exhibits an unstable nature with its 'beta-gamma-delta' magnetic field configuration, which holds the potential for intense solar flares. According to NOAA forecasters, there is a 75% probability of M-class flares and a 30% chance of X-flares on May 22nd. Keep an eye on the skies as the sun prepares to unleash its energetic bursts of electromagnetic radiation.

SUBSIDING CHANCE OF FLARES: NOAA forecasters have decreased the odds of an X-class flare from 30% (yesterday) to 20% (today). This is in response to decay in the magnetic field of sunspot AR3311, currently the biggest threat for flares on the solar disk. 20% is still plenty, though, for an X-class explosion.
