A movie made from a series of high-resolution observations (44-km per pixel image scale), taken over a period of 1 hour and 10 minutes using the Swedish 1-m Solar Telescope (SST) and showing coronal rain formation. The field-of-view is dominated by small-scale jets (spicules), as observed in the red-wing of the H-alpha 656.3-nm spectral line. A part of a C-class solar flare is seen as a bright flash in the top-left edge of the image (approx. half-way through the movie), which is followed by many dark threaded flows (i.e. coronal rain) in the second half of the movie, which appear to be falling back to the solar surface from bottom-right to top-left. The field of view in the image is 16,000 by 20,000 kilometres. Credit: E. Scullion / SST
