Impact Summary
- Next 24 hours: No risk of radio blackouts, no risk of solar radiation storms.
- Moderate geomagnetic activity with minor geomagnetic storms expected.
- G1-G2 (Minor-Moderate) geomagnetic storms likely early on February 17 due to persistent CH HSS influences.
- No significant active regions forecasted to produce radiation storms.
- Slight chance for R1-R2 (Minor-Moderate) radio blackouts through February 19.
Long Term Forecast
- Impact Summary
- From February 16 to March 14, 2026, solar activity is expected to continue at low levels.
- A slight chance for M-class (R1-R2, Minor-Moderate) flares from February 16 to 21, with increased activity from February 22 to March 7 as Region 4366 returns to visibility.
- Forecast includes a potential for X-class (R3-Strong) flares during the peak activity period.
- Greater than 10 MeV proton flux is likely to remain below S1 (Minor) levels on February 16-21 and March 8-14, but may reach S1-S2 (Minor-Moderate) storm levels between February 22 and March 7.
- Geomagnetic field activity is expected to range from unsettled to active levels on specific dates due to recurrent negative polarity CH HSS effects, with opportunities for active conditions on March 12 and 14.
- Mostly quiet to unsettled levels are anticipated during the breaks between storm periods.
