Radio Blackouts Probability
- Minor: 55
- Major: 10
- Risk: None
-
Solar Radiation
- Probability: 5
- Risk: None
-
Geomagnetic Storming
- Scale: 3
- Impact: strong
- Activity: High
-
Impact Summary
- No risk of radio blackouts; operations should be unaffected.
- No risk of solar radiation storms; satellite operators can expect a stable environment.
- High geomagnetic activity anticipated, posing risks primarily to satellite communication systems, with potential increases in drag for LEO satellites. No G1 (Minor) or greater geomagnetic storms expected.
Long Term Forecast
- Impact Summary
- Solar activity likely to remain low, with isolated M-class flares possible; monitor for minor disruptions.
- No significant proton events are anticipated at geosynchronous orbit, ensuring stable conditions for satellites in that region.
- Increased electron flux expected at geosynchronous orbit on specific dates, which may affect satellite operations; applicable preventive measures should be in place.
- Periods of unsettled to active geomagnetic conditions forecasted on several dates, which may lead to increased operational challenges for ground-based radars and communication systems. Mostly quiet conditions are anticipated for the remaining days in the forecast period.
