3-day Solar-Geophysical Forecast
Product: 3-Day Forecast
- Issued: 2026 Feb 06 1230 UTC
Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center.
Geomagnetic Activity Observation and Forecast
The greatest observed 3 hr Kp over the past 24 hours was 3 (below NOAA Scale levels). The greatest expected 3 hr Kp for Feb 06-Feb 08 2026 is 4.67 (NOAA Scale G1).
| Feb 06 | Feb 07 | Feb 08 | |
|---|---|---|---|
| 00-03UT | 0.67 | 4.00 | 4.67 (G1) |
| 03-06UT | 1.67 | 2.67 | 3.67 |
| 06-09UT | 2.00 | 1.67 | 3.33 |
| 09-12UT | 3.00 | 1.67 | 3.33 |
| 12-15UT | 2.67 | 2.33 | 2.00 |
| 15-18UT | 3.00 | 2.67 | 3.33 |
| 18-21UT | 3.33 | 3.33 | 3.33 |
| 21-00UT | 4.67 (G1) | 4.00 | 3.67 |
Rationale: G1 (Minor) geomagnetic storms are likely on 06 and 08 Feb due to the anticipated arrival of two CMEs glancing impacts near Earth.
Solar Radiation Activity Observation and Forecast
Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was below S-scale storm level thresholds.
| Feb 06 | Feb 07 | Feb 08 | |
|---|---|---|---|
| S1 or greater | 25% | 25% | 25% |
Rationale: There is a chance for a S1 (Minor) solar radiation storms on 06-08 Feb due to the magnetic complexity and dynamic of the active regions on the visible disk.
Radio Blackout Activity and Forecast
Radio blackouts reaching the R1 levels were observed over the past 24 hours. The largest was at Feb 05 2026 1934 UTC.
| Feb 06 | Feb 07 | Feb 08 | |
|---|---|---|---|
| R1-R2 | 80% | 80% | 80% |
| R3 or greater | 35% | 35% | 35% |
Rationale: R1-R2 (Minor-Moderate) radio blackouts are expected, with a chance for R3 (Strong) or greater levels on 06-08 Feb due to the magnetic complexity and dynamic of the active regions on the visible disk.

Solar Cycle
The Solar Cycle is observed by counting the frequency and placement of sunspots visible on the Sun. The forecast comes from the Solar Cycle Prediction Panel representing NOAA, NASA and the International Space Environmental Services (ISES). The Prediction Panel has predicted Cycle 25 to reach a maximum of 115 occurring in July, 2025. The solar radio flux at 10.7 cm (2800 MHz) is an excellent indicator of solar activity. Often called the F10.7 index, it is one of the longest running records of solar activity. The F10.7 radio emissions originates high in the chromosphere and low in the corona of the solar atmosphere. The F10.7 correlates well with the sunspot number as well as a number of UltraViolet (UV) and visible solar irradiance records.
