SDO: The Sun HMIIF Continuum

This view of the Sun is captured in "visible light" wavelengths, so it's basically how you would see the Sun right now with your own eyes if you got close enough and could look at it without damaging your eyes. It's similiar to how you'd see it with a telescope equiped with a solar filter (although in that case you wouldn't see the colour). This is the best feed for identifying sunspots, which afterall are only called "spots" because they are the features on the Sun's disc that are visible to humans.
