Prediction of the thermospheric and ionospheric responses to the 21 June 2020 annular solar eclipse
Earth and Planetary Physics, 2020 On 21 June 2020, an annular solar eclipse will traverse the low latitudes from Africa to Southeast Asia. The highest latitude of the maximum eclipse obscuration is approximately 30°.

Variation of Low-Frequency Time-Code Signal Field Strength during the Annular Solar Eclipse on 21 June 2020: Observation and Analysis. [PDF]
Sensors (Basel), 2021 Due to the occlusion of the moon, an annular solar eclipse will have an effect on the ionosphere above the earth. The change of the ionosphere, for the low-frequency time-code signal that relies on it as a reflection medium for long-distance propagation,

First Global-Scale Synoptic Imaging of Solar Eclipse Effects in the Thermosphere. [PDF]
J Geophys Res Space Phys, 2020 A total solar eclipse occurred in the Southern Hemisphere on 2 July 2019 from approximately 17 to 22 UT. Its effect in the thermosphere over South America was imaged from geostationary orbit by NASA's Global‐scale Observation of Limb and Disk (GOLD ...

The Color and Brightness of the F-corona Inferred from the 2019 July 2 Total Solar Eclipse [PDF]
Astrophysical Journal, 2021 Total solar eclipses (TSEs) provide a unique opportunity to quantify the properties of the K-corona (electrons), F-corona (dust), and E-corona (ions) continuously from the solar surface out to a few solar radii.

Ionospheric monitoring with the Chilean GPS eyeball during the South American total solar eclipse on 2nd July 2019. [PDF]
Sci Rep, 2020 The impact of total solar eclipse of July 2, 2019 on the Ionosphere is studied using 24 Chilean GPS stations north–south of the totality path. The total solar eclipse passed through Coquimbo region from ~ 16:38 CLT (~ 20:38 UTC) to ~ 16:40 CLT (~ 20:40 ...

Changes in the surface broadband shortwave radiation budget during the 2017 eclipse [PDF]
Atmospheric Chemistry and Physics, 2020 While solar eclipses are known to greatly diminish the visible radiation reaching the surface of the Earth, less is known about the magnitude of the impact. We explore both the observed and modeled levels of change in surface radiation during the eclipse

The Solar Eclipse Predictions of Chiljeongsam-Oepyeon in Early Choseon [PDF]
Journal of Astronomy and Space Sciences, 2004 The history books of East Asia about astronomical phenomena have the more records of the solar eclipse frequently than any other ones. It is because traditionally, the solar eclipse meaned the fate of dynasty and the king's rule.
