Details:
A minor display of aurora - appearance comparisons - At 0200 UTC (2200 local time), I noticed a slight glow over the north treeline, checked (spaceweather.com, of course, and) https://www.swpc.noaa.gov/products/real-time-solar-wind, which indicated minor to moderate solar radiation, then looked again at 0320 UTC and there was a stronger glow with visible pillars.
The animation represents about ten minutes from 0320 to 0330 UTC, when clouds began to roll in, with images taken at settings ISO 800, 15s.
The dimmer still image was taken before and represents the scene much closer to the naked-eye view appearance (ISO 640, 2s).
The bright colorful image represents the "on blast" type of long exposure, which is nowhere near a naked-eye realistic depiction but closer to the eye-catching images often posted on social media to show what a camera may capture (ISO 1600, 30s).
The charts (and reports from later in the day) indicated the storm "hit" and was stronger near 0430 UTC. I peeked out again at that time to see mostly clouds.
