- Major: 1
- Risk: None
-
Solar Radiation
- Probability: 1
- Risk: None
-
Geomagnetic Storming
- Scale: 2
- Impact: moderate
- Activity: Moderate
-
Impact Summary
- Next 24 hours: No risk of radio blackouts.
- No risk of solar radiation storms.
- Moderate geomagnetic activity and moderate geomagnetic storms expected.
- Periods of G1 (Minor) storming likely on 15-16 Feb, with a chance for isolated G2 (Moderate) storming on 15 Feb due to positive polarity CH HSS influences.
- Weak CME enhancements are possible on 15 Feb as a CME from 11 Feb passes nearby.
- No significant active region activity forecasted for radiation storm production.
- Slight chance for R1-R2 (Minor-Moderate) radio blackouts through 17 Feb.
Long Term Forecast
- Impact Summary
- Solar activity is expected at moderate levels with further M-class (R1-R2, Minor-Moderate) flares anticipated and a chance for X-class (R3-Strong or greater) on 09-10 Feb as Region 4366 moves across the western limb.
- Low activity levels, with chances for M-class flares, expected from 11-22 Feb.
- An increase to moderate to high solar activity likely from 23-28 Feb as Region 4366 returns to the visible disk.
- Conditions will return to low to moderate levels from 01-07 Mar as Region 4366 rotates out of view.
- The 10 MeV proton flux may reach S1-S2 (Minor-Moderate) storm levels through 12 Feb.
- Following 12-22 Feb, levels are likely to be below S1 (Minor) levels with another potential increase on 23-28 Feb.
- High levels of the greater than 2 MeV electron flux at geosynchronous orbit are expected on key dates due to CH HSS influence.
- Geomagnetic field activity anticipated to fluctuate between unsettled and active levels throughout the forecast period, influenced by CH HSS effects.
