Impact Summary
- No risk of radio blackouts: Communication systems remain stable.
- No risk of solar radiation storms: Satellite operators can continue normal operations without concern for radiation effects.
- Moderate geomagnetic activity: Minor geomagnetic storms are expected, which could lead to fluctuations in high-frequency radio communication and GPS accuracy.
- Future geomagnetic outlook: Periods of G1 (Minor) geomagnetic storms are anticipated on 08-10 Dec, with stronger G2-G3 (Moderate-Strong) storms likely on 09 Dec due to a coronal mass ejection (CME) passage.
- Radiation outlook: Slight chance of S1 (Minor) or greater solar radiation storms on 08-10 Dec, potentially affecting satellite operations.
- Radio blackout outlook: R1-R2 (Minor-Moderate) radio blackouts are likely from 08-10 Dec, with a marginal risk for R3 (Strong) events.
Long Term Forecast
- Forecast of Solar and Geomagnetic Activity (08 December - 03 January 2026):
- M-class flares (R1-R2/Minor-Moderate) likely, with a small chance for X-class flares (R3/Strong) throughout the outlook period.
- Slight chance for greater than 10 MeV proton flux to reach 10 pfu (S1-Minor).
- Greater than 2 MeV electron flux expected to peak on 08-09, 12-13, 16-17, 25-29 Dec, and 01-03 Jan, with normal to moderate levels generally prevailing.
- Geomagnetic storm activity likely to reach G1 (Minor) levels on 08 and 10 Dec with anticipated G2-G3 (Moderate-Strong) storming on 09 Dec related to a CME from 06 Dec.
- Additional G1 storms probable on 21-23 Dec and again on 24-26 Dec due to coronal hole high-speed streams (CH HSS).
- G2 (Moderate) storms likely on 30 Dec with G1 storms on 31 Dec, influenced by negative polarity CH HSS.
