The Far-Infrared Absolute Spectrophotometer (FIRAS) on the COBE satellite, gives different temperatures of the Cosmic Microwave Background. This deviation has a theoretical explanation in the Doppler effect on the dipole (weak) component of the radiation, the true microwave background of the Universe that moves at 365 km/sec, if the monopole (strong) component of the radiation is due to the Earth. Owing to the Doppler effect, the dipole radiation temperature (determined by the 1st derivative of the monopole) is lower than the monopole radiation temperature, with a value equal to the observed deviation. By this theory, the WMAP and PLANCK satellites, targeting the L2 point ...
