Abstract

Understanding how space weather phenomenon affects daily life has been a main focus of space weather studies. In particular, identifying the relationship between solar activities, ionospheric irregularities and consequently ionospheric scintillation has inspired numerous research efforts. Geomagnetic storms fueled by solar activities cause ionospheric irregularities. Ionospheric scintillation occurs when radio signals travel through these irregularities and experience rapid fluctuations in radio signal phase and amplitude. Such fluctuations have great consequences in radio wave based technology such as the Global Position system(GPS) as it causes a loss of lock. Therefore, through the implantation of two GPS Receivers, continuous data was obtained on phase and amplitude of radio signals from the Global Navigation Satellite Systems(GNSS). This data was then thoroughly analyzed to identify scintillation signatures. On January 31st, 2019, scintillation signatures that correlated to a G1 minor geomagnetic storm were observed. In this paper, the method of analysis is adapted from the aforementioned case study to identify past geomagnetic events that possibly correlated with observed scintillation. Through this study, it is hoped that a correlation between geomagnetic storms and ionospheric scintillation in the mid-latitude region will be highlighted.

Investigation into Geomagnetic storms and ionospheric scintillation
