SORCE (SOlar Radiation and Climate Experiment) is an American (NASA) Sun-Earth Connection satellite that was launched at 20:13 UT by a Pegasus XL rocket released from a L-1011 cargo aircraft flying out of Cape Canaveral. It is to measure solar irradiance in a number of wavelength-bands through three spectrometers and a photometer.
