:Product: 3-Day Forecast :Issued: 2023 Nov 29 0030 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # A. NOAA Geomagnetic Activity Observation and Forecast The greatest observed 3 hr Kp over the past 24 hours was 2 (below NOAA Scale levels). The greatest expected 3 hr Kp for Nov 29-Dec 01 2023 is 5.67 (NOAA Scale G2). NOAA Kp index breakdown Nov 29-Dec 01 2023 Nov 29 Nov 30 Dec 01 00-03UT 1.67 5.00 (G1) 5.00 (G1) 03-06UT 2.00 5.33 (G1) 5.67 (G2) 06-09UT 1.33 4.67 (G1) 5.00 (G1) 09-12UT 1.33 4.00 4.33 12-15UT 2.00 3.33 4.00 15-18UT 2.33 3.00 3.00 18-21UT 2.67 3.33 3.33 21-00UT 4.00 3.67 3.67 Rationale: G1 (Minor) geomagnetic storming is likely, with a chance for an isolated G2 (Moderate) period, on 30 Nov as the 27 Nov CME effects continue. By 01 Dec, G2 (Moderate) conditions are likely with the anticipated arrival of the late 27 Nov/early 28 Nov CMEs. B. NOAA Solar Radiation Activity Observation and Forecast Solar radiation, as observed by NOAA GOES-16 over the past 24 hours, was below S-scale storm level thresholds. Solar Radiation Storm Forecast for Nov 29-Dec 01 2023 Nov 29 Nov 30 Dec 01 S1 or greater 10% 10% 10% Rationale: The greater than 10 MeV proton flux may experience a slight enhancement on 29 Nov due to the event produced by AR 3500 on the 28 Nov. Otherwise, background levels are expected to persist through 01 Dec. C. NOAA Radio Blackout Activity and Forecast Radio blackouts reaching the R2 levels were observed over the past 24 hours. The largest was at Nov 28 2023 1950 UTC. Radio Blackout Forecast for Nov 29-Dec 01 2023 Nov 29 Nov 30 Dec 01 R1-R2 40% 40% 40% R3 or greater 10% 10% 10% Rationale: There is a chance for isolated R1-R2 (Minor-Moderate) and a slight chance for Strong (R3) radio blackouts through 01 Dec primarily due to AR 3500.

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. |
