Solar Eclipse Effects on Electric and Magnetic Fields Near the Earth’s Surface on June 21, 2020
This study reveals that the magnetotelluric (MT) method can detect the responses of the ionospheric E-region to the annual solar eclipse on June 21, 2020. The MT method not only detected a significant reduction in the solar quiet current by approximately 3.3 h over Lijiang during the obscuration but also, for the first time, observed waves with periods ranging from a few to dozens of minutes in the electric field due to the eclipse. The evolution of electric and magnetic fields suggests nonstationary changes in the ionospheric E-region structures during and after the eclipse.
