The Sun is peppered with active regions (appear as lighter areas) indicating a high level of solar activity. In fact, a half a day earlier the Sun had unleashed a large coronal mass ejection as well as a mass of protons (some small white specks can still be seen). Material imaged here is ionized iron at about 1 million degrees K. in the emission line of 195 Angstroms.
