Ionospheric monitoring with the Chilean GPS eyeball during the South American total solar eclipse on 2nd July 2019

A. K. Maurya, M. N. Shrivastava, et al.

This research by Ajeet K. Maurya, Mahesh N. Shrivastava, and Kondapalli Niranjan Kumar explores how the July 2, 2019, total solar eclipse affected the ionosphere. Notably, while totality stations showed minimal changes, significant electron content decreases occurred to the south and increases to the north, hinting at a fascinating connection between the eclipse and atmospheric gravity waves.

Abstract
This paper investigates the impact of the July 2, 2019, total solar eclipse on the ionosphere using data from 24 Chilean GPS stations. Total electron content (TEC) variations showed minimal changes at totality stations but significant decreases south and increases north of the totality path. Wavelet analysis revealed atmospheric gravity waves (AGWs) north of totality. The results suggest an interplay between the eclipse's direct effect on ionospheric plasma density and AGW-induced perturbations.
