Radio Blackouts Probability
- Minor: 65
- Major: 20
- Risk: None
-
Solar Radiation
- Probability: 99
- Risk: None
-
Geomagnetic Storming
- Scale: 0
- Impact: none
- Activity: Low
-
Impact Summary
- No risk of radio blackouts.
- No risk of solar radiation storms.
- Geomagnetic outlook indicates low activity, providing a stable environment for satellite operations and ground-based observations.
Long Term Forecast
- Impact Summary
- Solar activity may exhibit low levels with potential for R1-R2 (Minor-Moderate) and a slight chance for R3 (Strong) radio blackouts, mainly due to multiple solar regions.
- Anticipated S1 (Minor) solar radiation storms expected on 19-20 Jan could impact satellite systems at geosynchronous orbit.
- High levels of electron flux expected during certain periods may affect satellite operations, especially for LEO satellites.
- Geomagnetic activity is forecasted to reach G1 (Minor) storm levels on 29 Jan, which could impact communication systems and satellite drag rates during that time. Most of the period is expected to remain quiet.
