Pc3 MAGNETIC PULSATION RECORDED BY GROUND-BASED MAGNETOMETER AT BIAK

Ground-based magnetometer at BIK records magnetic field variation with high sensitivity and 1-second time resolution. This paper will describe technique how to extract the Pc3 magnetic pulsation from data of ground-based magnetometer in BIK. We will also show that Pc3 magnetic pulsation has band-frequency in period between 10 – 45 second.
