Variability in the Occurrence of Sporadic E in the Geminid Meteor Shower using Inosonde BPAA Agam Data

Abstract

Variability in the appearance of sporadic E in the Geminid Meteor Shower. The appearance of sporadic E does not always exist and suddenly appears, so sporadic E appears as a result of the Geminid Meteor Shower. Therefore, this research aimed to determine the variability in the appearance of sporadic E during the Geminid Meteor Shower. This type of research was descriptive analysis research. This research includes data collection, data processing, and data analysis on sporadic E layers. The data was linked to the Geminid Meteor Shower events on December 12, 13, and 14 in 2014, 2019, and 2020. The results of this research show that there were significant differences in the appearance of the Sporadic E layer at the peak of the Geminid Meteor shower. Where it had increased foEs and h'Es as Sporadic E layer parameters. foEs and h'Es before the peak of the Geminid Meteor Shower were known to be normal with foEs values between 2-4.2 MHz and h'Es at an altitude of 102-147 km. When the Geminid Meteor Shower peaked, foEs increased to 11.67 MHz and h'Es at an altitude of 147 km. After the peak of the Geminid Meteor Shower, there was a decline until it returned to normal with foEs ranging between 2-4.4 MHz and h'Es at an altitude of 99-147 km. An increase in foEs and h'Es was associated with the Geminid Meteor Shower phenomenon, so the Geminid Meteor Shower was variability in the appearance of Sporadic E during the Geminid meteor shower
