Scientific paper

Using an array of four low latitude induction coil magnetometers, geomagnetic pulsations in the Pc3 period range were recorded simultaneously in southeast Australia. The data recording stations were situated at Woomera, Broken Hill, Newcastle and Launceston over a latitudinal range of 100 and a longitudinal range of 170 at L=1.8 to 2.7. Geomagnetic data for a period of about six months were digitized and analysis was carried out employing digital sonagram technique. The Pc3 occurrence was found to be evenly distributed with magnetic activity over the Kp = 2 - 5 range. Launceston, however, showed lower occurrences at low Kp values (Kp <2+) than the other three stations. The Pc3 occurrence probability normalized with respect to Kp occurrence was maximum for Kp = 4+ at all the four stations. It is also worth noting that Pc3 in winter was observed during intense magnetic activity when 5 < Kp <9. Finally, a gradual increase in the Pc3 average, lower and upper frequencies limit with Kp was observed during the local winter months for Kp <5. Key words - Pc3 geomagnetic pulsations, digital sonagram, diurnal variation of Pc3 occurrence, seasonal variation of Pc3 occurrence, Kp dependence.
