Start with whether you can see it tonight — then the same geomagnetic storm through five more questions: what drives it, where it's likely, how far south it reaches, and how it's moved. Each is its own quiet, moving picture.
A straight answer for your location — with the numbers, cloud and moon, and the best odds elsewhere.

→ 06 The record · latelyThree days of readings flowing through now into the three-day forecast — the whole arc on one line.
→Real space-weather driving a piece of generative art — no charts, no numbers, just the sky moving.
→Built on NOAA / SWPC open data — the OVATION aurora model, the planetary Kp index, real-time solar wind, and the 3-day forecast. Until the pipeline is live, each picture runs on an honest, clearly-marked illustrative pattern.
