TL;DR: In this paper, the authors present the results of the analysis of a numerical experiment on the generation of acoustic gravity waves (AGWs) in the lower atmosphere and their propagation into the upper atmosphere.
Abstract: This paper presents the results of the analysis of a numerical experiment on the generation of acoustic gravity waves (AGWs) in the lower atmosphere and their propagation into the upper atmosphere. The observed variations in atmospheric pressure during the passage of a solar eclipse on March 20, 2015, over Kaliningrad (54° N, 20° E) are considered the be a wave source. The calculation results showed that the passage of a solar eclipse is accompanied in the lower atmosphere by an increase in wave activity in the AGW range with periods of ~4–20 min. In the upper atmosphere, at altitudes of ~200 km, disturbances are formed due to the dissipation of AGWs coming from the lower atmosphere; these disturbances propagate with characteristic periods of ~50 min. The propagation direction of these disturbances was opposite to the propagation direction of the solar eclipse region along the Earth’s surface. The results of the numerical experiment are in qualitative agreement with the results of observations of ionospheric disturbances during the solar eclipse on March 20, 2015.

TL;DR: In this article, the authors established a relation between two gravitational anomalies: one that has attracted part of the scientific community, the Allais effect that occurs during solar eclipse; the other, noticed but forgotten by the whole scientific community.
Abstract: The purpose of this article is to establish a relation between two gravitational anomalies: one that has attracted part of the scientific community, the Allais effect that occurs during solar eclipse; the other, noticed but forgotten by the whole scientific community, the General Relativity’s residual arc of the curvature of rays of light in the solar gravitational field during the same eclipse. There is a systematically observed deflection about 10 percent larger than the theoretical value of General Relativity, which coincides with the «eclipse effect» found by Maurice Allais, thrown aside because it upsets the established truths. These corresponding anomalies were never explained by any theories and turn out to be new gravitational physics.

TL;DR: In this paper, the spectroscopic assignments of Olsen, Anderson and Stewart for their observed solar eclipse wavelengths in the near-infrared region between 1µm and 3 µm were reviewed in the light of more recent information.
Abstract: The spectroscopic assignments of Olsen, Anderson and Stewart (1971), for their observed solar eclipse wavelengths in the near-infrared region between 1µm and 3µm, are reviewed in the light of more recent information. Several assignments are shown to need revision, and alternate candidates are proposed, including the possibility of an interesting forbidden line emitted from the high metastable level 3s3p3d (4F9/2) of Fe XIV.
