    Summary - (Jul 23, 2004) Using data gathered by NASA's SORCE satellite, scientists noticed that the light from the Sun reaching the Earth decreased by 0.1% during the Venus transit earlier this year. This is similar to what happens when large sunspots obscure the face of the Sun. In October 2003, three large sunspot groups moving across the Sun dimmed it by 0.3%. These large sunspots are surrounded by bright areas called "faculae", which actually compensate for the dimmer spots, and provide a net increase in sunlight when measured over a period of a few weeks.

    I thought it seemed a bit cooler that morning.
