Abstract

The effect of total solar eclipse on ionospheric total electron contents (TECs) over the ionospheric region of Indonesia was studied using GNSS-/GPS-based retrieved data. Continuous TEC analysis in conjunction with total solar eclipse of 09 March 2016 has been made from 08 to 10 March 2016 over Cibinong station of Indonesia sector (6° 28′ S, 106° 51′ E). Over Cibinong GNSS/GPS station of Indonesia, around ~ 94% of maximum obscurity of solar eclipse was observed. The eclipse event reached its maximum development at 00:58 UTC on 09 March 2016 with a magnitude (the fraction of the angular diameter of a celestial body being eclipsed) 1.045 and a duration of around 210 s (3 m 10 s). Results of the ionospheric vertical total electron contents during the total solar eclipse of 09 March 2016 over the Indonesian region were compared with the normal days. GNSS-/GPS-measured TEC over Cibinong of Indonesia was observed to be less than the pre- and post-eclipse days before the occurrence of total solar eclipse, but these were found to be more than the pre-eclipse day and less than the post-eclipse day after the occurrence of total solar eclipse of 09 March 2016. For both pre- and post-eclipse days, trend lines of proton temperature were found to have negative slopes, whereas a positively increasing trend line was observed on the eclipse day of 09 March 2016. The proton fluxes with energy (> 10 MeV) were found to show almost similar behavior on pre-, post-, and eclipse days of the study period. However, a small but positive constant slope was found on pre-eclipse day.
