Next 24 Hours
-
Radio Blackouts Probability
- Minor: 55
- Major: 15
- Risk: None
-
Solar Radiation
- Probability: 10
- Risk: None
-
Geomagnetic Storming
- Scale: 1
- Impact: minor
- Activity: Moderate
-
Impact Summary
- Next 24 hours: No risk of radio blackouts or solar radiation storms.
- Moderate geomagnetic activity is expected with minor geomagnetic storms likely due to a combination of a recent CME and a negative polarity coronal hole.
- A slight chance of S1 or greater solar radiation storms exists due to potential from Region 4274 as it rotates further around the Sun’s west limb.
- R1-R2 (Minor-Moderate) radio blackouts are likely, with a slight chance for R3 (Strong) blackouts due to flare potential from Region 4274.
Long Term Forecast
- Impact Summary
- From 17 November to 13 December, solar activity is likely to see R1 (Minor) levels and could increase to R1-R3 (Minor-Strong) levels during the end of November to early December.
- No proton events are expected at geosynchronous orbit, but high levels of electron flux are anticipated during specific periods influenced by coronal holes.
- Geomagnetic activity could range from quiet to G2 (Moderate) levels, with G1 conditions expected on 17 November and G2 levels likely on 26 November, 3 December, and 13 December.
- Unsettled to active conditions are anticipated on several days, primarily driven by coronal hole high-speed streams, while mostly quiet levels are expected on other specified days.
