Abstract

We present initial morphological features of the Global Positioning Systems (GPS) L1 and L2 band amplitude scintillations at Tarawa equatorial station (geog: 1.33°N, 173.01°E, geomag: 2.68°S, 114.26°W), Kiribati, for the period September 2017 to November 2018 which falls in the low solar activity period of solar cycle 24 (average sunspot number, 11.6). The scintillation data were analyzed for the diurnal and seasonal variations, geomagnetic activity, and solar flare dependences of the S4 index. No daytime scintillations were observed during the entire study period on either of the bands. Nighttime scintillations had maximum occurrence during equinox months followed by summer and winter. L2 band showed an increased level of scintillation activity compared to the L1 band. The scintillation activity was enhanced during the magnetically disturbed days compared to quiet days. Scintillations during geomagnetic storms were dominantly confined in the pre-midnight hours and scintillations were completely absent during solar flare events.
