From NOAA's Space Watch notifications:

Space Weather Message Code: ALTK08

Serial Number: 50

Issue Time: 2025 Apr 16 2054 UTC

ALERT: Geomagnetic K-index of 8, 9-

Threshold Reached: 2025 Apr 16 2055 UTC

Synoptic Period: 1800-2100 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.

Last May I saw the most intense solar storm since 2003's aurora in Colorado and it was amazing. If you're within the range of the projections, absolutely make time for it. This is probably going to be the most intense storm since then if it doesn't surpass it.
