Next 24 Hours
-
Radio Blackouts Probability
- Minor: 10
- 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.
- No risk of solar radiation storms.
- Geomagnetic outlook: G1 (Minor) geomagnetic storms are likely on December 22-23 due to anticipated high-speed streams from a positive polarity coronal hole becoming geoeffective.
- Radiation outlook: No significant active regions are expected to produce S1 (Minor) or greater solar radiation storms.
- There is a slight chance for R1-R2 (Minor-Moderate) radio blackouts on December 21-22, with an increased chance on December 23 as active regions return to the visible solar disk.
Long Term Forecast
- Impact Summary
- Forecast from December 15 to January 10, 2026: M-class flares (R1-R2/Minor-Moderate) are likely, with a chance for X-class (R3/Strong) flares if new, more magnetically complex regions develop.
- Greater than 10 MeV proton flux expected to remain below the 10 pfu (S1-Minor) levels throughout the period.
- Greater than 2 MeV electron flux may reach high levels on December 16-19, 25-29, and January 01-06, with normal to moderate levels on other specified dates.
- Geomagnetic activity may reach G1 (Minor) storm levels on December 18, 30-31, and possibly January 09 due to negative polarity coronal hole high-speed stream influences.
- Unsettled to active levels likely on several dates in December and January, with mostly quiet conditions anticipated on December 21 and January 04-08.
