Aurora Forecast Update for 2025-11-05T23:00:05Z

ALERT: Geomagnetic K-index of 6
Threshold Reached: 2025 Nov 05 2252 UTC
Synoptic Period: 2100-2400 UTC

Active Warning: Yes
NOAA Scale: G2 - Moderate
Additional Details Here.
Space Weather Message Code: ALTK06 Serial Number: 665 Issue Time: 2025 Nov 05 2253 UTC ALERT: Geomagnetic K-index of 6 Threshold Reached: 2025 Nov 05 2252 UTC Synoptic Period: 2100-2400 UTC Active Warning: Yes NOAA Scale: G2 - Moderate NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/noaa-scales-explanation Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude. Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms. Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible. Radio - HF (high frequency) radio propagation can fade at higher latitudes. Aurora - Aurora may be seen as low as New York to Wisconsin to Washington state. :Product: 3-Day Forecast :Issued: 2025 Nov 05 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 4 (below NOAA Scale levels). The greatest expected 3 hr Kp for Nov 05-Nov 07 2025 is 5.00 (NOAA Scale G1). NOAA Kp index breakdown Nov 05-Nov 07 2025 Nov 05 Nov 06 Nov 07 00-03UT 4.00 2.33 5.00 (G1) 03-06UT 3.33 3.00 4.67 (G1) 06-09UT 4.33 3.00 4.00 09-12UT 2.33 3.00 3.33 12-15UT 3.00 3.00 3.00 15-18UT 2.33 3.33 2.67 18-21UT 2.67 3.33 2.67 21-00UT 2.67 4.67 (G1) 3.67 Rationale: G1 (Minor) with a slight chance for G2 (Moderate) geomagnetic storm conditions are likely on 06-07 Nov due to CH HSS activity coupled with a possible glancing blow from the 03-04 Nov CMEs. B. NOAA 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. Solar Radiation Storm Forecast for Nov 05-Nov 07 2025 Nov 05 Nov 06 Nov 07 S1 or greater 25% 25% 25% Rationale: There is a chance for the greater than 10 MeV proton flux reaching the S1 (Minor) threshold on 05-07 Nov due to the flare potential of Region 4274. 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 04 2025 1734 UTC. Radio Blackout Forecast for Nov 05-Nov 07 2025 Nov 05 Nov 06 Nov 07 R1-R2 70% 70% 70% R3 or greater 25% 25% 25% Rationale: Probabilities have increased to 70% for R1-R2 (Minor-Moderate) and 25% for R3 (Strong) due to the continued activity and complex structure of Region 4274.

Trump just continually shooting our country in the face. This unwarranted (and likely illegal) destruction of Goddard is madness. It jeopardizes the next several decades of space exploration.

Reposting to correct an error: trump admin is quietly gutting 13 buildings and about 100 laboratories at Goddard campus that has been instrumental to Hubble and James Webb telescope missions. Staff say they’ve be locked and told to move equipment. Anything left behind will be thrown away.

Right in time for #Halloween 🎃

Our VST has spotted a spooky bat flying over Paranal. But fear not, it's located 10,000 light-years away.

This "cosmic bat" is in fact a large cloud of gas. Let's fly through it in this video...if you dare! 🦇
