Abstract :
This study investigated the low latitude nocturnal ionospheric irregularities at India-Arab longitudes using phase fluctuations of the global positioning system during solar maximum. The results showed that the low latitude irregularities in this region develop easier in equinoctial months and December-solstice months than in June-solstice months. In addition, the low latitude irregularities mainly come from the magnetic equator. Moreover, at the crest of equatorial anomaly the irregularities in June-solstice months maybe come from middle latitudes. Many details are discussed.
