Earth's ionosphere, a natural plasma, is locally similar to nighttime conditions during a solar eclipse, in that the Moon blocks solar radiation and causes extremely complex and nonlinear processes. It is known that the peak electron density (NmF2) of the F2 layer with maximum ionization varies non-linearly depending on solar activity F10.7 solar flux, geomagnetic field, geographic latitude and longitude, local time and season. In this study, the variation of NmF2 and hmF2 during the annular solar eclipse of 10 June 2021 was investigated theoretically and the results were compared with TR170 URSI coded digisonde data in Tromsø.
