Long Term Forecast
- Forecast of Solar and Geomagnetic Activity 19 January - 14 February 2026:
- Solar activity is likely to remain at low levels, with a chance for R1-R2 (Minor-Moderate) and a slight chance for R3 (Strong) levels over the next forecast period, all due to multiple regions on the visible disk as well as regions expected to return.
- 10 Mev at 10 pfu proton events (S1-Minor) are expected at geosynchronous orbit on 19-20 Jan.
- The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 19-27 Jan and 12-14 Feb, all due to the anticipated influence of multiple, recurrent coronal holes.
- The remainder of the outlook period is likely to be at normal to moderate levels.
- Geomagnetic field activity is likely to reach (G1-Minor) geomagnetic storm levels on 29 Jan and unsettled to active levels on 19-23, 27-28, 30-31 Jan, 04-11 and 13-14 Feb.
- All enhancements in activity are due to the anticipated influence of multiple, recurrent CH HSSs.
- The remainder of the outlook period is expected to be mostly quiet.
