Radio Blackouts Probability
- Minor: 40
- Major: 5
- Risk: None
-
Solar Radiation
- Probability: 5
- Risk: None
-
Geomagnetic Storming
- Scale: 0
- Impact: none
- Activity: Low
-
Impact Summary
- Next 24 hours: No risk of radio blackouts or solar radiation storms. A G1 (Minor) geomagnetic storm is likely on 22 Sep due to negative polarity coronal hole high-speed stream (CH HSS) effects. No significant active region activity is expected to produce radiation storms, maintaining a mainly quiet environment.
Long Term Forecast
- Impact Summary
- From 15 September to 11 October 2025, solar activity will remain low with the possibility of isolated M-class flares. Geosynchronous orbit will not experience proton events. An increase in electrons is expected due to recurring CH HSS activities on specific dates, indicating potential elevated risk for satellite operations. Geomagnetic activities forecasted include G2 (Moderate) conditions on 15 Sep and G1 (Minor) conditions on several dates, necessitating monitoring for satellite communication disruptions and drag on low Earth orbit (LEO) satellites.
