    • Probability: 1
    • Risk: None
  • Geomagnetic Storming

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

    • Next 24 hours: No risk of radio blackouts.
    • No risk of solar radiation storms.
    • Geomagnetic outlook: No G1 (Minor) or greater geomagnetic storms are expected.
    • No significant transient or recurrent solar wind features are forecast.
    • Radiation outlook: No S1 (Minor) or greater solar radiation storms are expected.
    • No significant active region activity favorable for radiation storm production is forecast.
    • Radio blackout outlook: There is a chance for isolated R1-R2 (Minor-Moderate) radio blackouts over 15-17 Dec.

Long Term Forecast

  • Impact Summary
    • Forecast of solar and geomagnetic activity from 15 December to 10 January 2026: M-class flares (R1-R2/Minor-Moderate) are likely, with a chance for X-class (R3/Strong) flares through the outlook period.
    • Chances could increase if new, more magnetically complex regions develop or return during the period.
    • The greater than 10 MeV proton flux is expected to remain below the 10 pfu (S1-Minor) levels throughout the outlook period.
    • The greater than 2 MeV electron flux is expected to reach high levels on 16-19 Dec, 25-29 Dec, and 01-06 Jan, with normal to moderate levels expected on 15, 20-24, 30-31 Dec, and 07-10 Jan.
    • Geomagnetic field activity is likely to reach G1 (Minor) storm levels on 18 Dec, 30-31 Dec, and possibly 09 Jan, due to negative polarity coronal hole high-speed stream (CH HSS) influences.
    • G1 levels are also likely on 22-26 Dec, due to positive polarity CH HSS influences.
    • Unsettled to active levels are likely on 15-17, 19-20 Dec, 01-03 Jan, and 08-10 Jan under the influence of negative polarity CH HSS, with additional activity expected on 27-29 Dec under positive polarity CH HSS influence.
    • Mostly quiet conditions are expected on 21 Dec and 04-08 Jan.
