Radio Blackouts Probability
- Minor: 45
- Major: 5
- Risk: None
-
Solar Radiation
- Probability: 5
- Risk: None
-
Geomagnetic Storming
- Scale: 0
- Impact: none
- Activity: Low

Impact Summary
- Next 24 hours: No risk of radio blackouts expected; communication systems will remain stable.
- No solar radiation storms are predicted, ensuring minimal risk for satellite operations.
- Geomagnetic conditions are low, but a G1 (Minor) geomagnetic storm may occur on January 28, influenced by negative polarity coronal hole high-speed stream (CH HSS).
- Watch for potential R1-R2 (Minor-Moderate) radio blackouts between January 26-28, which could briefly disrupt high-frequency communications.
Long Term Forecast
- Impact Summary
- From January 26 to February 21, low solar activity is anticipated, with occasional chances for M-class flares (R1-R2/Minor-Moderate).
- No proton events are forecasted at geosynchronous orbit, providing a stable environment for satellite operations.
- High levels of greater than 2 MeV electron flux are expected on January 26 and January 28-31, as well as February 1-3, February 6-12, and February 15-21, which may affect satellite systems sensitive to electron flux.
- Geomagnetic activity is likely to reach G1 (Minor) storm levels on January 28 and February 13, with additional active periods expected, which could impact navigational systems.
- Overall, quiet and settled conditions are expected for most of the forecast period, providing a relatively predictable environment for space operations.
