Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Extreme conditions during storms profoundly alter the evolution of equatorial plasma bubbles (EPBs), yet the key dynamics remains poorly understood. We document the rapid expansion, contraction, and decay of super EPBs in South America during the 12 November 2025 storm with Interplanetary Magnetic Field (IMF) Bz/By magnitude exceeding ∼50 nT ...

Contrasting behavior of slow and fast photoreactive gases during the August 21, 2017, solar eclipse
Elementa: Science of the Anthropocene, 2018 The total solar eclipse on August 21, 2017, provided a rare opportunity to observe and test our understanding of atmospheric dynamics and photochemical dependency on solar irradiance.

Two Practical Methods for Coronal Intensity Determination
, 2017 Determining the relative brightness of the solar corona is one of the most critical stages in solar eclipse studies. For this purpose, images taken with different exposures and polarization angles in white-light observations are used. The composite image

Solar Activity Dependence of the Dayside Lunar Surface Potential in the Terrestrial Magnetotail
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract On the dayside of the Moon, the surface potential is primarily determined by (a) photoelectron emission by solar radiation and (b) the ambient plasma environment. Both of these drivers have large variability, but the resulting variability of the lunar surface potential has not been fully characterized yet.

Annular and Total Solar Eclipses of 2010 [PDF]
While most NASA eclipse bulletins cover a single eclipse, this publication presents predictions for two solar eclipses during 2010. This has required a different organization of the material into the following sections. Section 1 -- Eclipse Predictions:

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.Abstract We present atmospheric chlorine inventories over 21 years (2004–2024) and five latitude bands (82–60°N, 60–30°N, 30°N–30°S, 30–60°S, 60–82°S) across altitudes from the surface up to 61 km. These inventories were calculated using the Atmospheric Chemistry Experiment‐Fourier Transform Spectrometer (ACE‐FTS) version 5.3 retrievals of the volume ...

Eclipse radius measurements [PDF]
Methods for predicting the path edges and reducing observations of total solar eclipses for determining variations of the solar radius are described. Analyzed observations of the 1925 January eclipse show a 0.7 (arc second) decrease in the solar radius ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.Abstract In situ measurements of stratospheric aerosol are the only measurements that provide sufficient detail to determine aerosol number, size, surface area, volume/mass, and effective radius; however, these measurements are limited in space and time.
