The X-Class Flare of January 2014

Early January of 2014 saw one of the largest sunspot groups of solar cycle 24 and some X-class flares near the center of the solar disk from active region AR 11943. These flares launched a few small coronal mass ejections towards the Earth.

At the ultraviolet wavelength of 160 nm, we see an image which still resembles the view in visible light, but with the faculae surrounding the sunspots more visible. The flare appears like a bright arc from the regions.

At the wavelength of the helium ion at 30.4 nm, magnetic loops around the active region are far more visible and we see streams of plasma moving around the region before and after the flare.
