AIA 0131 channel (as well as AIA 094) is designed to study solar flares. It measures extremely hot temperatures around 10 million K (18 million F), as well as cool plasmas around 400,000 K (720,000 F). It can take images every 2 seconds (instead of 10) in a reduced field of view in order to look at flares in more detail. Where: Flaring regions of the corona Wavelength: 131 angstroms (0.0000000131 m) = Extreme Ultraviolet Primary ions seen: 20 and 7 times ionized iron (Fe VIII, Fe XXI) Characteristic temperatures: 10 million K (18 million F)
