Global Hazard Watch

• Space weather stays quiet to moderate with two off-Earth CMEs and no geomagnetic, radiation, or flare alerts
• No expected GNSS, HF radio, or...

• Aditya-L1 detected small, short-lived brightening in the Sun's atmosphere hours before major flares, clustering at the exact future flare sites.

EarlyDetect AI detects solar active regions 9.24 hours before they appear, potentially giving satellite operators and grid managers extra time to...

An M6.9 flare erupted Aug 25 from sunspot 4513, launching a CME that may graze Earth Aug 28 while a high-speed solar wind stream arrives Aug 27.

The Atlantic is getting busier with two disturbances monitored, yet hostile conditions from wind shear, dry air, and ongoing El Niño make development...

New data reveal CMEs can hide fast-moving Earth-directed components missed from our viewpoint, so Saucier residents should treat space weather alerts with extra caution and maintain emergency plans for potential grid or comms disruptions.

A record 17 spacecraft tracked a December 2024 CME with two asymmetric lobes—one fast toward Earth at 522 miles per second, the other slower at 332...

Geomagnetic conditions stayed quiet on Aug 22 with Kp at 1.0 and no significant coronal holes. Sunspot 4513 carries a delta magnetic field that could produce X-class flares, though current solar wind and flare levels remain low.

• Atlantic basin remains slow with just 3 named storms and low ACE so far
• A robust tropical wave may form a storm in the MDR early next week despite...

• M8.1 flare from Region 4513 launched a large CME now confirmed heading east and away from Earth.
• The source region's east-limb location made an...

A complex CME with an irregular shape slipped past Earth-based monitors, but was caught by Europa Clipper's PIMS instrument, exposing a dangerous gap...

Solar Cycle 25 has already outpaced forecasts with 31% more daily sunspots than Cycle 24, exposing limits in traditional models that rely on past...

A filament eruption on August 14 sent a glancing-blow CME toward Earth, due to arrive today and spark G1-G2 conditions. SOLAR-1, now fully operational...

Solar activity remained low with a C8.2 flare launching a CME now under analysis for any Earth-directed effects. A separate filament CME is due 17-18...

• New analysis of 25 years of data shows upper-atmosphere currents keep rising with stronger solar wind, erasing the familiar saturation curve.

The PRESTO ALERT system issues plain-text warnings ASAP for significant solar events like partial-halo CMEs that may affect Earth's space environment. This rapid notification from SIDC supports proactive monitoring of space weather developments.

Extreme solar storms can spike radiation to nearly 10 times normal levels at typical flight altitudes while triggering electronics failures that...

• Radiation spikes during solar storms can cause Single Event Upsets in aircraft electronics, leading to incidents like the A320's sudden drop and...

• EarlyDetect model spots hidden solar active region signals an average of 9.24 hours before emergence, using acoustic and magnetic data from NASA's...

NASA's ensemble model nailed the August 8 CME's arrival at Earth to the exact minute—10:32 UTC on August 11—but its 22-hour uncertainty window...
