copy cw in your head

Aurora Forecast Update for 2025-11-12T21:00:05Z

EXTENDED WARNING: Geomagnetic K-index of 7 or greater expected
Extension to Serial Number: 137
Valid From: 2025 Nov 12 0020 UTC
Now Valid Until: 2025 Nov 13 0900 UTC
Warning Condition: Persistence
Additional Details Here.
Space Weather Message Code: WARK07 Serial Number: 138 Issue Time: 2025 Nov 12 2054 UTC EXTENDED WARNING: Geomagnetic K-index of 7 or greater expected Extension to Serial Number: 137 Valid From: 2025 Nov 12 0020 UTC Now Valid Until: 2025 Nov 13 0900 UTC Warning Condition: Persistence NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/noaa-scales-explanation Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude. Induced Currents - Power system voltage irregularities possible, false alarms may be triggered on some protection devices. Spacecraft - Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur. Navigation - Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur. Radio - HF (high frequency) radio may be intermittent. Aurora - Aurora may be seen as low as Pennsylvania to Iowa to Oregon. :Product: 3-Day Forecast :Issued: 2025 Nov 12 1230 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 8.67 (NOAA Scale G4). The greatest expected 3 hr Kp for Nov 12-Nov 14 2025 is 8.67 (NOAA Scale G4). NOAA Kp index breakdown Nov 12-Nov 14 2025 Nov 12 Nov 13 Nov 14 00-03UT 8.67 (G4) 6.67 (G3) 4.67 (G1) 03-06UT 8.33 (G4) 6.33 (G2) 4.00 06-09UT 7.00 (G3) 6.00 (G2) 3.33 09-12UT 7.00 (G3) 4.67 (G1) 3.67 12-15UT 6.00 (G2) 4.00 3.33 15-18UT 5.67 (G2) 3.33 3.00 18-21UT 7.67 (G4) 4.33 3.00 21-00UT 6.00 (G2) 4.67 (G1) 3.33 Rationale: Up to G4 (Severe) geomagnetic storms are expected on 12 Nov due to CME influences. G3 (Strong) geomagnetic storms are likely on 13 Nov and G1 (Minor) geomagnetic storms are likely on 14 Nov due to CME effects. B. NOAA Solar Radiation Activity Observation and Forecast Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was above S-scale storm level thresholds. Solar Radiation Storm Forecast for Nov 12-Nov 14 2025 Nov 12 Nov 13 Nov 14 S1 or greater 99% 75% 55% Rationale: S1-S2 (Minor to Moderate) or greater solar radiation storms are expected over 12-14 Nov. C. NOAA Radio Blackout Activity and Forecast No radio blackouts were observed over the past 24 hours. Radio Blackout Forecast for Nov 12-Nov 14 2025 Nov 12 Nov 13 Nov 14 R1-R2 80% 80% 80% R3 or greater 55% 55% 55% Rationale: R1-R2 (Minor-Moderate) radio blackouts are expected and R3 (Strong) radio blackouts are likely over 12-14 Nov.

Looks like it's time to swing that VHF antenna due North 🌠🌈 #solarstorm #aurora

Or not? NOAA/SWPC's own plots are still showing planetary K-index of 5.33. For a G4 storm, it needs to be 8.

Protons are raining down massively though.

Before a #CME hits Earth's magnetic field, high-speed solar wind streams and energetic particles can already reach Earth. These interact with the ionosphere, particularly the F2 layer. This interaction can temporarily increase ionization in the upper ionosphere #hamradio #spacewx
