Scientific paper

In this investigation terrestrial magnetic records for 1929-1985 from the Auroral Observatory in Tromso have been examined for giant micropulsations (Pg). This period encompasses five solar cycles and supplements the work of Harang (1941). In agreement with Harang, an anticorrelation with the solar cycle is found in the frequency of occurrence of the micropulsations. A seasonal variation with maxima in March and September is clearly revealed, as already indicated in Harang's much more limited data set. Also in support of Harang, it is found that the period of oscillation tends to increase for long-lasting pulsations and for recurring ones. Contrary to Harang, who found a daily maximum between 0100 and 0200 UT, however, the maximum is found to occur somewhere between 0200 and 0300 UT.
