The images are made automatically with a fixed, gentle rule: uneven illumination and most of the limb darkening are removed, and the brightness is shown on a linear scale (no sharpening); prominences get their own scale outside the limb. Frames are ordered by sharpness (seeing); frames without the Sun (darks, bias) come last. Method →

The animations are stabilised (the disk stays in place). The brightness scale is chosen once for the whole film from the sharpest frames, so a real flare shows up as a brightening. Method →
Top: the brightest disk points (quiet Sun = 1); a sudden rise may be a flare. Bottom: bright and dark (sunspot) area as a percentage of the disk.
