🌌Space Weather

Next 24 Hours

  • Radio Blackouts Probability

    • Minor: 15
    • Major: 1
    • Risk: None
  • Solar Radiation

    • Probability: 1
    • Risk: None
  • Geomagnetic Storming

    • Scale: 0
    • Impact: none
    • Activity: Low
  • Impact Summary

    • Next 24 hours: No risk of radio blackouts and no solar radiation storms expected. The geomagnetic activity outlook indicates the possibility of G1 (Minor) geomagnetic storms on December 18 due to a coronal hole high-speed stream. Radio blackout outlook shows a slight chance for R1-R2 (Minor-Moderate) radio blackouts anticipated through December 18.

Long Term Forecast

  • Forecast of Solar and Geomagnetic Activity (December 15 - January 10, 2026): M-class flares (R1-R2/Minor-Moderate) are likely, with potential for X-class (R3/Strong) flares depending on development of new active regions. The greater than 10 MeV proton flux is expected to remain below S1 (Minor) levels. Increased levels of the greater than 2 MeV electron flux are predicted for December 16-19, 25-29, and January 01-06, while normal to moderate levels are likely on December 15, 20-24, 30-31, and January 07-10. Geomagnetic activity might reach G1 (Minor) storm levels on December 18, 30-31, and possibly January 09, influenced by coronal hole high-speed stream activities. Other unsettled to active periods are expected as noted, with mostly quiet conditions anticipated on December 21 and January 04-08.
