Impact Summary
- Next 24 hours: No risk of radio blackouts.
- No risk of solar radiation storms.
- Moderate geomagnetic activity with a likelihood of minor geomagnetic storms.
- Geomagnetic outlook indicates a G1 (Minor) geomagnetic storm risk due to a waning coronal mass ejection (CME) and a coronal hole.
- Radiation outlook shows no significant activity favorable for radiation storm production.
Long Term Forecast
- Impact Summary
- From 01-27 September, solar activity is expected to remain low, but there will be varying chances for M-class flares (R1-R2/Minor-Moderate).
- Enhanced levels of greater than 10 MeV protons could be experienced early in September, but generally expected below significant thresholds.
- Geomagnetic activity is predicted to reach G2 (Moderate) levels initially, transitioning to G3 (Strong) levels shortly thereafter, particularly influenced by a recent CME.
- Active geomagnetic conditions are anticipated on several occasions throughout September, specifically linked to coronal hole high-speed streams (HSS).
- Overall quiet to unsettled levels are expected during the latter part of the month, potentially easing impacts on satellites and communication systems.
