[en] To facilitate the statistical analysis of ULF magnetic waves observed at the synchronous orbit, and to expedite the selection of suitable intervals for comparison of SMS/GOES data with observations on the ground and on other satellites, a catalog of low-frequency magnetic oscillations observed at the SMS/GOES locations was compiled. This report covers the period November 1974 through March 1975, and includes observations from the satellite SMS-1, which was located at 75 degrees west geographic longitude. Pulsation events are catalogued which display at least five continuous cycles and a frequency which is roughly constant. When different frequencies are present at the same time, each is identified as an event. Only pulsations with a peak amplitude of at least 3 gammas are included in the catalog
