Abstraction: Real-time space weather forecasts for solar flares, geomagnetic storms, and asteroids
Key points:
- NOAA forecasts on July 4-5, 2026: 75% probability of M-class solar flare within 24 hours; 20% probability of X-class
- A G3-class geomagnetic storm on July 3-4 triggered visible auroras across most US states, unusual for near-solstice due to the Russell-McPherron Effect suppressing auroras at solstices
- A new active sunspot produced an X1.3-class flare on July 4, causing shortwave radio blackouts over North America; associated CME will miss Earth
- On July 4, 2026, NASA all-sky cameras detected 43 fireballs (all sporadic) over the US
- 2,349 potentially hazardous asteroids tracked as of July 5, 2026; none on collision course with Earth
- Atmospheric radiation at a 10-year low in late 2024 due to heightened Solar Cycle 25 activity repelling cosmic rays
