Aurora Forecast Update for 2025-11-12T03:52:14Z

ALERT: Geomagnetic K-index of 8, 9-
Threshold Reached: 2025 Nov 12 0345 UTC
Synoptic Period: 0300-0600 UTC

Active Warning: Yes
NOAA Scale: G4 - Severe
Additional Details Here.
Space Weather Message Code: ALTK08 Serial Number: 54 Issue Time: 2025 Nov 12 0346 UTC ALERT: Geomagnetic K-index of 8, 9- Threshold Reached: 2025 Nov 12 0345 UTC Synoptic Period: 0300-0600 UTC Active Warning: Yes NOAA Scale: G4 - Severe NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/noaa-scales-explanation Potential Impacts: Area of impact primarily poleward of 45 degrees Geomagnetic Latitude. Induced Currents - Possible widespread voltage control problems and some protective systems may mistakenly trip out key assets from the power grid. Induced pipeline currents intensify. Spacecraft - Systems may experience surface charging; increased drag on low earth orbit satellites, and tracking and orientation problems may occur. Navigation - Satellite navigation (GPS) degraded or inoperable for hours. Radio - HF (high frequency) radio propagation sporadic or blacked out. Aurora - Aurora may be seen as low as Alabama and northern California. :Product: 3-Day Forecast :Issued: 2025 Nov 12 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 3 (below NOAA Scale levels). The greatest expected 3 hr Kp for Nov 12-Nov 14 2025 is 8.00 (NOAA Scale G4). NOAA Kp index breakdown Nov 12-Nov 14 2025 Nov 12 Nov 13 Nov 14 00-03UT 5.00 (G1) 6.67 (G3) 4.67 (G1) 03-06UT 7.33 (G3) 6.33 (G2) 4.00 06-09UT 6.00 (G2) 6.00 (G2) 3.33 09-12UT 4.67 (G1) 4.67 (G1) 3.67 12-15UT 4.33 4.00 3.33 15-18UT 8.00 (G4) 3.33 3.00 18-21UT 7.67 (G4) 4.33 3.00 21-00UT 7.00 (G3) 4.67 (G1) 3.33 Rationale: CME activity from 09-11 Nov is likely to cause G1-G4 (Minor-Severe) levels on 12 Nov, G1-G3 (Minor-Strong) storm levels on 13 Nov and G1 (Minor) levels early on 14 Nov. 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: The greater than 10 MeV proton flux is expected to continue above the S1 (Minor) threshold through 13 Nov, with S2 levels possible through 12 Nov. Further enhancements are possible with the arrival of the 09-11 Nov CMEs on 11 and 12 Nov. C. NOAA Radio Blackout Activity and Forecast Radio blackouts reaching the R3 levels were observed over the past 24 hours. The largest was at Nov 11 2025 1004 UTC. Radio Blackout Forecast for Nov 12-Nov 14 2025 Nov 12 Nov 13 Nov 14 R1-R2 85% 85% 85% R3 or greater 55% 55% 55% Rationale: R1-R2 (Minor-Moderate) radio blackouts are expected, with further R3 (Strong) activity likely on 12-14 Nov due to the flare potential of Region 4274.
