Long Term Forecast
- Impact Summary
- Forecast of Solar and Geomagnetic Activity from 08 September to 04 October: Solar activity is expected to be mostly low, with chances for moderate (R1-R2/Minor-Moderate) activity due to multiple complex regions both on the visible disk and those returning from the Sun’s farside.
- No proton events are forecast at geosynchronous orbit.
- The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels over 08-11 Sep and 20-21 Sep due to recurrent coronal hole high-speed streams (CH HSSs).
- Geomagnetic field activity is likely to vary from quiet to G1 (Minor) geomagnetic storm levels.
- G1 conditions are expected on 15 Sep; active conditions may occur on 08 Sep, 14 Sep, 16 Sep, 28-29 Sep, and 03-04 Oct; unsettled conditions on 09-10 Sep, 17-19 Sep, and 30 Sep.
- All increases in geomagnetic activity are anticipated due to multiple recurrent CH HSSs, while the remainder of the period is expected to be mostly quiet.
