There might be another one tonight. Feel better! bsky.app/profile/auro...
aurora.nws-bot.us Aurora Forecast Bot from NOAA (UNOFFICIAL) @aurora.nws-bot.us · 5d
Aurora Forecast Update for 2025-11-12T10:40:04Z

ALERT: Geomagnetic K-index of 7
Threshold Reached: 2025 Nov 12 1033 UTC
Synoptic Period: 0900-1200 UTC

Active Warning: Yes
NOAA Scale: G3 - Strong
Additional Details Here.
Space Weather Message Code: ALTK07 Serial Number: 197 Issue Time: 2025 Nov 12 1038 UTC ALERT: Geomagnetic K-index of 7 Threshold Reached: 2025 Nov 12 1033 UTC Synoptic Period: 0900-1200 UTC Active Warning: Yes NOAA Scale: G3 - Strong 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 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.

Aww, no, you’re cool. Always dig fellow scientists. Don’t dig: “Magic-Education_Stars.com who is totally going to make my students up-vote me on Instagram” 🤷🏻‍♀️

Genuine question: how often has this come up? It just feels really strange; have none of them ever looked at a map of Siberia before? Even the Nile flows north

Nice! Think you would appreciate this (and yes, I took some 🙂):

I am in Iowa City actually. Getting my PhD in the geography department, though we just merged with geology

lol same! I even mapped out the entire tunnel system in the Selenitic age
