Can an impulsive variation of the solar wind plasma pressure trigger a plasma bubble? A case study based on CSES, Swarm and THEMIS data [PDF]

, 2020
During the August 25, 2018 geomagnetic storm, the new borne CSES-01 satellite and the Swarm A satellite detected a really large equatorial plasma bubble (EPB) in the post-midnight sector over western Africa.

OI 630 nm Airglow Observed From Space as a Diagnostic of Nighttime Low‐Latitude Ionospheric Dynamics

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study investigates the nighttime morphology of the bottomside F region (∼250 km) at low latitudes using 630 nm airglow measurements from the Visible and Infrared Spectral Imager (VISI) aboard the Ionosphere, Mesosphere, Upper Atmosphere, and Plasmasphere (IMAP) mission on the International Space Station. For this purpose, we analyzed IMAP/

Analysis of equatorial plasma bubble zonal drift velocities in the Pacific sector by imaging techniques [PDF]

Annales Geophysicae, 2007
Using 1024 nights of data from 2002–2005 taken by the Cornell Narrow Field Imager (CNFI), we examine equatorial plasma bubble (EPB) zonal drift velocity characteristics.

Why Do Small‐Scale Irregularities Migrate Beyond the Equatorial Plasma Bubble?

Geophysical Research Letters
F‐region Field‐Aligned Irregularities (FAIs) observed by the Hainan Coherent Scatter Phased Array Radar (HCOPAR) and the Equatorial Plasma Bubbles (EPBs) observed by four All‐Sky Airglow Imagers (ASAIs) in the night of 4 November 2023 were compared.

Statistical Analysis of Equatorial Plasma Bubbles Climatology and Multi‐Day Periodicity Using GOLD Observations

Geophysical Research Letters, 2023
This study develops a new Bubble Index to quantify the intensity of 2‐D postsunset equatorial plasma bubbles (EPBs) in the American/Atlantic sector, using Global‐scale Observations of the Limb and Disk (GOLD) nighttime data.

Ionospheric Mechanisms Leading to Plasma‐Bubble Zonal Drift Reversal and Deformation During the 12 November 2025 Geomagnetic Storm

Space Weather, Volume 24, Issue 10, October 2026.
Abstract We present a multi‐instrument analysis of the ionospheric response to the intense geomagnetic storm of 12 November 2025 over the American sector, with emphasis on the longitudinally asymmetric deformation, latitudinal expansion, and zonal drift reversal of equatorial plasma bubbles (EPBs).

ScintPi 4.0: A New GNSS‐Based Low‐Cost, Multi‐Constellation, Multi‐Frequency Ionospheric Scintillation and TEC Monitor for Education, Citizen Science, and Research Initiatives

Space Weather, Volume 24, Issue 10, October 2026.
Abstract ScintPi is a series of alternative ionospheric scintillation and total electron content (TEC) monitors. ScintPi monitors have been built by combining single‐board computers (Raspberry Pi) and commercial off‐the‐shelf (COTS) Global Navigation Satellite System (GNSS) receivers.

Stepping Into an Equatorial Plasma Bubble With a Swarm Overfly

Space Weather, 2023
ESA's Swarm constellation entered in a “overfly” configuration in the period between September and October 2021, when the longitudinal distance between the lower pair and the upper satellite was at its minimum since the launch of the spacecrafts.

Photovoltaic Stimulation of Mouse and Pig Retina With Pyrolytic Carbon Microelectrodes Integrated on High‐Density Silicon Solar Cell Arrays

Advanced Healthcare Materials, Volume 15, Issue 36, 25 September 2026.
In this study, we fabricate photovoltaic retinal implants with pyrolytic carbon electrodes and test their ability to stimulate mouse and pig retinas when illuminated with near‐infrared light. We find increased spiking activity in both animal models compared to spontaneous activity and TTX controls and analyze the spike amplitude, latency and frequency.

Linear Programming Optimization of Nutritional and Technological Properties in Wheat Bread Fortified With Taioba (Xanthosoma sagittifolium L.) Leaf Flour

Cereal Chemistry, Volume 103, Issue 5, Page 754-766, September/October 2026.
ABSTRACT Background and Objectives This study applied linear programming to optimize taioba (Xanthosoma sagittifolium) leaf flour (TLF) incorporation in wheat bread, balancing nutritional enrichment and technological quality. Findings Breads containing 0%–15% TLF (flour basis) were produced and evaluated for composition, dough expansion, specific ...
