Impact Summary
- Next 24 hours: No risk of radio blackouts or solar radiation storms. Geomagnetic outlook shows no G1 (Minor) or greater storms are anticipated. Additionally, no significant transient or recurrent solar wind features are expected, which is beneficial for satellite operations and ground-based instruments.
Long Term Forecast
- Impact Summary
- For the period of 22 September - 18 October 2025, solar activity will likely remain low, with minor chances for isolated M-class flares.
- No proton events are expected at geosynchronous orbit, reducing radiation threats to satellites.
- High levels of greater than 2 MeV electron flux are anticipated during several periods, which may affect satellite systems.
- Geomagnetic activity is expected to reach G1 (Minor) storm levels intermittently during this forecast, potentially impacting communication systems and satellite operations during those times.
