3-day Solar-Geophysical Forecast
Product: 3-Day Forecast
- Issued: 2025 Nov 08 0030 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 5 (NOAA Scale G1). The greatest expected 3 hr Kp for Nov 08-Nov 10 2025 is 5.67 (NOAA Scale G2).
| Nov 08 | Nov 09 | Nov 10 | |
|---|---|---|---|
| 00-03UT | 4.00 | 4.67 (G1) | 3.00 |
| 03-06UT | 4.00 | 3.67 | 4.67 (G1) |
| 06-09UT | 4.00 | 3.00 | 5.67 (G2) |
| 09-12UT | 3.67 | 3.00 | 4.67 (G1) |
| 12-15UT | 4.33 | 2.00 | 4.33 |
| 15-18UT | 4.67 (G1) | 2.33 | 3.67 |
| 18-21UT | 5.67 (G2) | 3.33 | 2.67 |
| 21-00UT | 4.67 (G1) | 3.33 | 2.67 |
Rationale: G1-G2 (Minor-Moderate) geomagnetic storms are likely over 08-10 Nov due to a combination of coronal hole influence and multiple CMEs.
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.
| Nov 08 | Nov 09 | Nov 10 | |
|---|---|---|---|
| S1 or greater | 20% | 20% | 20% |
Rationale: There exists a slight chance for S1 (Minor) solar radiation storms over 08-10 Nov due primarily to the eruptive potential of Region 4274.
Radio Blackout Activity and Forecast
Radio blackouts reaching the R1 levels were observed over the past 24 hours. The largest was at Nov 07 2025 0716 UTC.
| Nov 08 | Nov 09 | Nov 10 | |
|---|---|---|---|
| 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), over 08-10 Nov predominantly due to the flare potential of Region 4274.

The sun is constantly monitored for sun spots and coronal mass ejections. EIT (Extreme ultraviolet Imaging Telescope) images the solar atmosphere at several wavelengths, and therefore, shows solar material at different temperatures. In the images taken at 304 Angstrom the bright material is at 60,000 to 80,000 degrees Kelvin. In those taken at 171 Angstrom, at 1 million degrees. 195 Angstrom images correspond to about 1.5 million Kelvin, 284 Angstrom to 2 million degrees. The hotter the temperature, the higher you look in the solar atmosphere.

Instruments on board the NOAA Polar-orbiting Operational Environmental Satellite (POES) continually monitor the power flux carried by the protons and electrons that produce aurora in the atmosphere. SWPC has developed a technique that uses the power flux observations obtained during a single pass of the satellite over a polar region (which takes about 25 minutes) to estimate the total power deposited in an entire polar region by these auroral particles. The power input estimate is converted to an auroral activity index that ranges from 1 to 10.
