Eight days of solar flares on NASA video
NASA has released a video showing eight days of solar flares produced by the largest sunspot in the past two dozen years.
Known as AR 2192, the video is a time lapse that shows its X-class flares in both visible and ultraviolet light using images taken by the Solar Dynamics Observatory Atmospheric Imaging Assembly Instrument.
The massive sunspot, which has now rotated away from Earth, produced the most powerful X-class flares between the 19 and 27 October, plus many more medium-class flares during that same period.
The video is online in several places, including YouTube at tinyurl.com/sunspot-AR2192.
