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 3 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Dec 09-Dec 11 2024 is 2.67 (below NOAA
Scale levels).

21-00UT | 2.33 | 2.33 | 2.33 |
Rationale: No G1 (Minor) or greater geomagnetic storms are expected. No significant transient or recurrent solar wind features are forecast.
Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was below S-scale storm level thresholds.
Dec 09 | Dec 10 | Dec 11 | |
---|---|---|---|
S1 or greater | 10% | 5% | 5% |
Rationale: There is a slight chance for S1 (Minor) solar radiation storms on 09 Dec.
Radio blackouts reaching the R3 levels were observed over the past 24 hours. The largest was at Dec 08 2024 0906 UTC.
Dec 09 | Dec 10 | Dec 11 | |
---|---|---|---|
R1-R2 | 60% | 50% | 50% |
R3 or greater | 10% | 10% | 5% |
Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely on 09 Dec, with a slight chance for R3 (Strong) or greater events on 09-10 Dec.

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. |
