The Solar 'Constant' - Faculae vs. Sunspots

There is a newer version of this story located here:
Three views of the Sun showing different levels of solar activity. The color table has been altered to enhance the appearance of the faculae (white regions) which are hotter than sunspots (red-black regions) and whose greater total area contribute to increasing the solar flux reaching the Earth.
