That's raw NASA SDO satellite footage. Claude (Opus 4.7) was used almost exclusively for building the site. Static site on Render (no hosting fees), pushed from Github. Uses NASA API's (free), a very cost-friendly project on the ole wallet!

I'll add that "raw" is after a bit of postprocessing to make it pretty.

When the SDO webserver went down a few months ago I rebuilt the L1 data processing pipeline from JSOC so we could still do outreach and there's a surprising amount of opinion that goes into the mapping of data to visualization for each wavelength. My composite movies came out looking more like an acid trip than solar data.

Touché — when the person who rebuilt the pipeline says it's not raw, it's not raw :)

Is optical-flow interpolation a step too far for outreach, or fair game? Tempted to motion-interpolate (ffmpeg's minterpolate) the daily MP4s up to 60fps for Lumara— looks gorgeous but the in-between frames are extrapolated. You're totally right about "raw", I suppose I meant more straight from NASA APIs.

		I personally would rather show actual data over interpolated data, but I don't know how many unphysical interpolation artifacts you're getting or whether that really matters at a public outreach level. That said, if you felt like processing it yourself, the L1 files are available every 12-24 seconds, and preprocessed images are available ~1 per minute. The synoptic version you're using is about 1 frame every 3 minutes at 20 fps so you could just triple the framerate without needing any interpolation, or string together the images yourself.
