fade-out
  • A gradual disappearance of images and/or sounds, such as might occur at the end of a movie or song.
  • A rapid and complete loss of electromagnetic skywave signals, due to substantially increased ionization in the ionosphere. This ionization is caused by increased solar noise, which itself is caused by solar storms. It may last from a few minutes to several hours. Also called radio fadeout, Dellinger fadeout, or Dellinger effect.
