Resolution No.10 (1973): Use of the term "magnetic pulsation" or "pulsation"

IAGA recommends the use of the term "magnetic pulsation" or simply "pulsation" instead of "micropulsation" for the following reasons:

  1. The amplitude of pulsations is often large with respect to the main field in the outer magnetosphere.
  2. The wavelength of pulsations may be large with respect to the size of the earth.
