Abstract :
This article provides insight about signal amplitude variations of VLF electromagnetic waves by observing 10 communications radio stations at the same time. The amplitude variations of received VLF signals were compared with Solar flux number, geomagnetic KP-index and Earthquake data. The issues addressed include analysis of ionosphere parameters gathered for different geographical regions. The article especially reflects ongoing research within the Tbilisi State University Ionosphere Observatory.
