So apparently I have just been at ground zero or a coronal mass ejection aurora...

It really looked like this...

I am speechless

Zoom Into the Sun

Fall into our nearest star in this gorgeous high-resolution view of the Sun. Taken by Solar Orbiter, a joint NASA-ESA mission, the image stretches from the fiery photosphere -- full of filaments and prominences -- to the wispy yet unbelievably hot corona. (Image credit: ESA & NASA/Solar Orbiter/EUI Team, E.

Huge 500,000-mile-wide hole opens in Sun

A vast 500,000-mile-wide coronal hole has opened in the Sun's atmosphere. The area measures over 62 times the diameter of Earth and is now shooting high-speed solar wind toward Earth. When such solar activity is directed at Earth, the resulting geomagnetic storms can potentially disrupt satellite operations, power grids, navigation systems, and radio communications. There may also be spectacular displays of aurora caused as the Earth's magnetosphere is disturbed by the solar wind. According to spaceweather.com, this wind is estimated to hit Earth by Friday (Jan. 31), resulting in G1 geomagnetic storm conditions.

While G1 storms are considered the mildest category, they can still have noticeable effects, particularly in terms of aurora visibility at higher latitudes.

Pacific northwest. INSANE geomagnetic storm!!!

Never thought I'd see aurora borealis right at home. Woagh.

G4 (Severe) Geomagnetic Storm Watch in Effect for 2 June UTC-Day | NOAA / NWS Space Weather Prediction Center

G4 (SEVERE) GEOMAGNETIC STORM WATCH IN EFFECT FOR 2 JUNE UTC-DAY

published: Saturday, May 31, 2025 20:43 UTC

A G4 (Severe) geomagnetic storm watch is in effect for 2 June. A powerful coronal mass ejection (CME) erupted from the Sun the evening of 30 May. The CME is anticipated to arrive at Earth later on Sunday, 1 June. The CME arrival will likely lead to immediate geomagnetic disturbances with the potential for G3 (Strong) levels, and a chance for G4. Conditions will likely intensify as CME progression continues and G4 levels become more possible on Monday, 2 June. Geomagnetic storm levels will likely begin subsiding by Tuesday, 3 June, with G1-G2 (Minor-Moderate) still possible. Confidence in an Earth-arrival component to this CME is good. However, timing and intensity are more uncertain. These watches represent potential based on our best analyses. We will not know the true nature of this CME’s geomagnetic storm potential until the CME arrives at our solar wind observatories located 1 million miles from Earth. Upon arrival at those spacecraft, we will know the magnetic strength and orientation that are very important to what levels and duration of geomagnetic storm conditions are expected to occur.
