Second‐Scale Formation of Non‐Field‐Aligned Plasma Irregularities Observed From a High‐Altitude 43‐Cassiopeiids Fireball

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract High‐altitude optical meteors initiating above 150 km are exceedingly rare, with confirmed observations largely confined to the Leonids. Using the Meteor and ionospheric Irregularity Observation System, we recorded a bright 43‐Cassiopeiids fireball with heterogeneous material. It initiated luminously at an exceptional altitude of 157.8 ± $\pm $

Daytime Ionospheric F‐Region Topside Irregularities Associated With Significant Density Enhancement at Low Latitudes During the 12 November 2025 Magnetic Storm

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract In this study, daytime F‐region irregularities were observed at low latitudes during the main phase of the 12 November 2025 strong magnetic storm, causing intense very high frequency radar echoes ranging hundreds of kilometers in altitude.

Barium Isotopes Indicate Spatiotemporal Heterogeneity of Marine Primary Productivity During the Toarcian Oceanic Anoxic Event

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.
