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.
