Product: 3-Day Forecast
- Issued: 2025 Feb 15 0030 UTC
Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center.
The greatest observed 3 hr Kp over the past 24 hours was 5 (NOAA Scale
G1).
The greatest expected 3 hr Kp for Feb 15-Feb 17 2025 is 5.00 (NOAA Scale
G1).
Feb 15 | Feb 16 | Feb 17 | |
---|---|---|---|
00-03UT | 5.00 (G1) | 3.33 | 2.67 |
03-06UT | 4.33 | 3.00 | 2.67 |
06-09UT | 3.33 | 2.67 | 2.33 |
09-12UT | 3.00 | 2.00 | 2.33 |
12-15UT | 2.33 | 2.00 | 2.33 |
15-18UT | 3.00 | 4.00 | 2.33 |
18-21UT | 3.00 | 4.00 | 2.67 |
21-00UT | 3.67 | 3.33 | 2.00 |
Rationale: G1 (Minor) geomagnetic storms are likely on 15 Feb due to CH HSS influences.
Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was below S-scale storm level thresholds.
Feb 15 | Feb 16 | Feb 17 | |
---|---|---|---|
S1 or greater | 5% | 5% | 5% |
Rationale: No S1 (Minor) or greater solar radiation storms are expected. No significant active region activity favorable for radiation storm production is forecast.
Radio blackouts reaching the R1 levels were observed over the past 24 hours. The largest was at Feb 14 2025 2057 UTC.
Feb 15 | Feb 16 | Feb 17 | |
---|---|---|---|
R1-R2 | 45% | 45% | 45% |
R3 or greater | 10% | 10% | 10% |
Rationale: There is a chance for R1-R2 (Minor-Moderate) radio blackouts over 15-17 Feb.

Images: From left to right: EIT 171, EIT 195, EIT 284, EIT 304 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. | |||

The MDI (Michelson Doppler Imager) images shown here are taken in the continuum near the Ni I 6768 Angstrom line.
The most prominent features are the sun spots. |
LASCO (Large Angle Spectrometric Coronagraph) is able to take images of the solar corona by blocking the light coming directly from the Sun with an occulter disk, creating an artificial eclipse within the instrument itself. |
