Abstract The Active Cavity Radiometer on board the SMM is providing high-quality measurements of the solar irradiance. After correction for the solar distance, the orbital displacement of the satellite, and the relativistic shift of irradiance due to the satellite motion, the observed standard deviation is in the range 10–15 parts per million in a 96-minute integration. Measurable solar variations occur on time scales of a few minutes to a few days. The total amplitude of the variations in the daily averages from February 16 to March 31, 1980, was 0.10% based upon 96-minute averages.
