The 94 angstroms channel allows the study of solar flares, measuring temperatures around 6 million Kelvin. The 171 angstroms channel is very good at showing coronal loops. The 193 and 335 angstroms channels highlight the outer atmosphere of the Sun, the corona. The 304 angstroms channel shows the areas where the plasma has a high density.
