Are plasma bubbles a prerequisite for the formation of broad plasma depletions in the equatorial F region?

, 2013
Formation of broad plasma depletions (BPDs) at night in the equatorial F region is understood in association with plasma bubbles. However, we report BPDs that do not show a connection with bubbles.

Localization and Classification of Gravity Wave Events From VIIRS Day/Night Band Satellite Imagery Using Machine Learning Techniques

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Gravity waves in the upper mesosphere produce diverse spatial patterns in nighttime airglow, but their global morphology has been difficult to characterize because manual identification is impractical for the massive satellite image archive. We developed a machine learning framework to detect and classify gravity wave events in imagery from ...

Dynamic spectral characteristics of high-resolution simulated equatorial plasma bubbles

Progress in Earth and Planetary Science, 2018
Manifestations of severe nighttime equatorial ionospheric disturbances have been observed for decades. It is generally accepted that the phenomena are caused by large depletions, referred to as equatorial plasma bubbles (EPBs), which are initiated on the

Longitudinal Variation of Ionospheric Irregularities and Response of the Ionosphere During 10–13 May and 10–13 October 2024 Geomagnetic Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We examine the response of the ionosphere to the 10–13 May 2024 and 10–13 October 2024 geomagnetic storms, the two recent great geomagnetic storms of solar cycle 25. We identified the occurrence of ionospheric irregularities during the two geomagnetic storms.

Investigating the Leptokurtotic Nature of Low‐Latitude GNSS Scintillations With a Multiscale Approach

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We investigate the statistical nature of Global Navigation Satellite System (GNSS) signal fluctuations through the multiscale analysis of a strong scintillation event recorded at the Ionospheric Observatory of the Luigi Broglio Space Center in Malindi, Kenya.

Self‐Limiting of Artificial Electron Radiation Belts: Evidence From the Starfish Prime High‐Altitude Nuclear Explosion

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The 1962 Starfish Prime high‐altitude 1.4‐megaton nuclear detonation injected large amounts of fission‐produced energetic electrons into the inner magnetosphere (L = 1.12), creating an intense artificial radiation belt that persisted for years. In this study, we revisit historical data from this unprecedented event to investigate the potential

A Possible Explanation of Interhemispheric Asymmetry of Equatorial Plasma Bubbles in Airglow Images [PDF]

, 2020
Equatorial plasma bubbles resulting from equatorial spread urn:x-wiley:jgra:media:jgra55597:jgra55597-math-0002 are well known to be aligned along the Earth's geomagnetic fields. During the geomagnetic storm on 17 March 2015, all‐sky airglow observations

Unexpected Field-Aligned Structure in Equatorial Plasma Bubbles

Equatorial plasma bubbles, commonly known as EPBs, are field-aligned ionospheric irregularities in the bottomside of the F-region equatorial ionosphere generated due to the RayleighTaylor instability.
