michael.h.f.wilkinson Posted April 25, 2016 Share Posted April 25, 2016 Just did a reprocess of some stacks on the north-eastern part of the sun in H-alpha, stacking more frames (200 instead of 100 out of 1000) to bring out more prom detail. There is definitely something on the limb. Looks like the kind of swirl of filaments you see around some sunspots.
