Impact Summary
- Next 24 hours: No risk of radio blackouts.
- No risk of solar radiation storms.
- Geomagnetic outlook: G1 (Minor) geomagnetic storms are likely on 06 Nov due to CME/HSS arrival.
- Radiation outlook: No S1 (Minor) or greater solar radiation storms are expected.
- No significant active region activity favorable for radiation storm production is forecast.
- Radio blackout outlook: R1-R2 (Minor-Moderate) radio blackouts are likely, with a slight chance for an isolated (R3-Strong) event through 06 Nov.
Long Term Forecast
- Impact Summary
- Forecast period: 03 November - 29 November.
- Solar activity is expected at moderate levels from 03-17 Nov due to the delayed return of Regions 4246 and 4248, rotating into the Earthside solar disk.
- At least two other regions are expected to emerge from the East limb until 10 Nov.
- Moderate solar activity could continue through 29 Nov if these regions are magnetically complex.
- No proton events are expected at geosynchronous orbit; however, an isolated proton event is possible between 07-12 Nov if Regions 4246 and 4248 show enhanced activity.
- The greater than 2 MeV electron flux at geosynchronous orbit is expected to remain high until 13 Nov, with moderate levels from 14-26 Nov, and high levels returning on 27 Nov.
- Geomagnetic field activity is expected to be mostly quiet to active, with minor storming (G1) likely on 07-08, 15, and 26-27 Nov due to recurrence of CH HSS influences.
