Solar X-ray Flux Screensaver
The Solar X-ray Flux screensaver shows six hours of one-minute solar X-ray samples from NOAA's key-less GOES feed. Flare class is logarithmic — each letter is ten times the last — so the band lines make an X-class flare legible instead of hiding it. It's free, runs in your browser, and ESC exits.

Frequently asked questions
- Is this real data?
- Yes — it comes from NOAA's GOES feed and is refreshed on a schedule.
- Why the lettered bands?
- Flare class is logarithmic: each letter is ten times the one below. On a linear axis an X-class flare would swamp everything; the bands keep the whole range readable.
- Is a key needed?
- No. This source is fully key-less.
- Is it free?
- Yes — free, no download, in your browser.
