2024-11-04 10:24 AM | ALERT: Type IV Radio Emission Begin Time: 2024 Nov 04 0134 UTC Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms. |
3-day Solar-Geophysical Forecast
Product: 3-Day Forecast
- Issued: 2024 Nov 04 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 4 (below NOAA Scale levels). The greatest expected 3 hr Kp for Nov 04-Nov 06 2024 is 4.33 (below NOAA Scale levels).
Nov 04 | Nov 05 | Nov 06 | |
---|---|---|---|
00-03UT | 4.00 | 2.67 | 1.33 |
03-06UT | 4.33 | 2.67 | 1.33 |
06-09UT | 2.67 | 2.67 | 1.33 |
09-12UT | 2.33 | 2.00 | 1.33 |
12-15UT | 2.00 | 1.67 | 1.33 |
15-18UT | 1.67 | 1.00 | 1.67 |
18-21UT | 2.00 | 1.67 | 1.67 |
21-00UT | 2.00 | 1.67 | 1.67 |
Rationale: No G1 (Minor) or greater geomagnetic storms are expected. No significant transient or recurrent solar wind features are forecast.
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 04 | Nov 05 | Nov 06 | |
---|---|---|---|
S1 or greater | 20% | 10% | 5% |
Rationale: There is a slight chance for the greater than 10 MeV proton flux to remain elevated but below the threshold over 04-05 Nov.
Radio Blackout Activity and Forecast
Radio blackouts reaching the R1 levels were observed over the past 24 hours. The largest was at Nov 04 2024 0140 UTC.
Nov 04 | Nov 05 | Nov 06 | |
---|---|---|---|
R1-R2 | 95% | 80% | 75% |
R3 or greater | 30% | 30% | 20% |
Rationale: M-class (R1-minor) are expected through 06 Nov. There is a chance for X-class (R3-strong) on 04-05 Nov, decreasing to a slight chance on 06 Nov.

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.
