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 $

The Role of Planetary Rotation in Polar Cusp Localization

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Juno observations have revealed that Jupiter's polar cusps are displaced toward dusk and even the nightside, contradicting the Earth‐derived paradigm that is confined to narrower ranges near noon. These findings underscore the overlooked influence of planetary rotation on magnetospheric dynamics, exposing a critical gap in current theoretical ...

Downward Positive Leader Propagation Modes and Their Effects in Positive Cloud‐to‐Ground Lightning Characteristics

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The return stroke in a cloud‐to‐ground (CG) flash is initiated when the downward leader either reaches the ground or connects with an upward leader from a grounded structure. Unlike negative downward leaders, which typically propagate in a highly branched manner, downward positive leaders (DPLs) can propagate either in a branched or unbranched
