Ionospheric Responses at Low Latitudes to the Annular Solar Eclipse on 21 June 2020

open access: yesJournal of Geophysical Research: Space Physics, 2020
In this study, we utilized both ground‐based and space‐borne observations including total electron content (TEC) from Beidou geostationary satellites, two‐dimensional TEC maps from the worldwide dense Global Navigation Satellite System receivers ...

The Late Solar Eclipse [PDF]

open access: greenNature, 1893
IN his account of the work of the Eclipse Expedition at Fundium Mr. Fowler seeks to explain his inability to obtain the photographs at the moment of totality by the assumption that he received the signal of the beginning of totality at least ten seconds too late, and he bases this assumption on his own estimate of the difference in time which elapsed ...

Height Dependency of Solar Eclipse Effects: The Ionospheric Perspective

open access: yesJournal of Geophysical Research: Space Physics, 2020
A reliable interpretation of solar eclipse effects on the geospace environment, and on the ionosphere in particular, necessitates a careful consideration of the so‐called eclipse geometry.

Restoring the top-of-atmosphere reflectance during solar eclipses: a proof of concept with the UV absorbing aerosol index measured by TROPOMI [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
During a solar eclipse the solar irradiance reaching the top of the atmosphere (TOA) is reduced in the Moon shadow. The solar irradiance is commonly measured by Earth observation satellites before the start of the solar eclipse and is not corrected for ...

Solar Neutrinos and the Eclipse Effect [PDF]

open access: yesPhysical Review D, 1999
The solar neutrino counting rate in a real time detector like Super--Kamiokanda, SNO, or Borexino is enhanced due to neutrino oscillations in the Moon during a partial or total solar eclipse.

Homogenizing Estimates of Heritability Among SOLAR-Eclipse, OpenMx, APACE, and FPHI Software Packages in Neuroimaging Data. [PDF]

open access: yesFront Neuroinform, 2019
Imaging genetic analyses use heritability calculations to measure the fraction of phenotypic variance attributable to additive genetic factors. We tested the agreement between heritability estimates provided by four methods that are used for heritability

Ionospheric measurements of relative coronal brightness during the total solar eclipses of 11 August, 1999 and 9 July, 1945 [PDF]

open access: yesAnnales Geophysicae, 2000
Swept-frequency (1-10 MHz) ionosonde measurements were made at Helston, Cornwall (50°06'N, 5°18'W) during the total solar eclipse on August 11, 1999. Soundings were made every three minutes.

Coordinated weather balloon solar radiation measurements during a solar eclipse. [PDF]

open access: yesPhilos Trans A Math Phys Eng Sci, 2016
Solar eclipses provide a rapidly changing solar radiation environment. These changes can be studied using simple photodiode sensors, if the radiation reaching the sensors is unaffected by cloud.Transporting the sensors aloft using standard meteorological

Anomalous Behavior of the Equatorial Ionization Anomaly During the 2 July 2019 Solar Eclipse

open access: yesJournal of Geophysical Research: Space Physics, 2020
A solar eclipse is a spectacular phenomenon resulting from a Sun‐Moon alignment as viewed from the Earth. Eclipses have a great influence on the state of the ionosphere and trigger significant variations during this extraordinary event, as daytime ...
