A Solar Squall

Hinode XRT was tracking a small active region on 4 September 2015 when it detected an x-ray squall just south of the region. XRT also took a full disk synoptic image during the event revealing the cause of the solar storm was the cusp-shaped sigmoid in the southern hemisphere.

The gale was strong enough to send a million degree jet streaking around the eastern part of the region although it appears the region itself was not directly hit. This faint squall lasted only a few hours with the area returning to normal early the next day.
