Abstract
The pulsation magnetometer at Ethio-Finno Observatory (EFO) has been operational since June 2004. The major objectives of this instrument is to characteristically investigate the ionospheric phenomena of the upper polar atmosphere. Results from the data analysis in time and frequency domain depicts existence of strong interferences which are not observed in other similar observatories. In this thesis we shall investigate the disturbance characteristics and delve out the cause of peaks by relating with solar activities, geomagnetic activities and local effects such as ferrous object, and ground loop. This is done by carefully investigating the data collected during some days and by conducting controlled experiment.
