The sunspot that released the first M-flare of 2017 provided a spectacular sunset
as it rotated behind the solar disk.
While at the solar limb, the region released several bright jets, flare cusps, and current sheets, all evidence of magnetic reconnection.
Eventually, the sunspot rotates behind the limb and the X-ray cloud dims while steadily sinking below a dark horizon. By the end of the movie, the brightest regions are hidden behind the solar limb, leaving only the twilight of the active region.
