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