Impact Summary
- Next 24 hours: No risk of radio blackouts or solar radiation storms.
- Moderate geomagnetic activity with minor geomagnetic storms expected.
- G1 (Minor) storming is likely on 09 Aug due to coronal hole high-speed stream (CH HSS) influence.
- There is a slight chance for S1 (Minor) storm levels from 09-11 Aug.
- Radio blackout outlook includes R1-R2 (Minor-Moderate) events, with a slight chance for R3 (Strong) or greater over the same period.
Long Term Forecast
- Forecast of Solar and Geomagnetic Activity 04 August - 30 August 2025:
- Solar activity is expected to be mostly low with chances of M-class (R1-R2, Minor-Moderate) flares during the period.
- No proton events are anticipated at geosynchronous orbit.
- Greater than 2 MeV electron flux is expected to be high on 12-18 Aug and 21-28 Aug due to CH HSS influences.
