-
Radio Blackouts Probability
- Minor: 25
- Major: 1
- Risk: None
-
Solar Radiation
- Probability: 1
- Risk: None
-
Geomagnetic Storming
- Scale: 0
- Impact: none
- Activity: Low
-
Impact Summary
- No risk of radio blackouts expected, ensuring stable communication for satellite operators.
- No risk of solar radiation storms means satellite communication remains uninterrupted.
- The geomagnetic outlook indicates no G1 (Minor) or greater geomagnetic storms are anticipated, minimizing drag impacts on Low Earth Orbit (LEO) satellites.
- No significant active regions are projected to contribute to radiation storm production.
Long Term Forecast
- Impact Summary
- Solar activity is expected to remain low with a chance for isolated M-class flares, which could potentially disrupt satellite operations if they occur.
- No proton events are projected at geosynchronous orbit, ensuring continued safety for satellites in that region.
- The greater than 2 MeV electron flux is anticipated to reach high levels on multiple occasions, which may increase the risk of radiation exposure to sensitive satellites.
- Geomagnetic activity is expected to fluctuate, with periods of G1 (Minor) storm levels likely. This could result in occasional disruptions to satellite operations and communication.
- Overall, periods of unsettled to active geomagnetic conditions may introduce non-significant drag effects on LEO satellites during late September and early October.
