First Results of a New Inversion Tool for Thermospheric Neutral Mass Density Computations During Severe Geomagnetic Storms

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract In Low Earth Orbit (LEO), atmospheric drag is the dominant source of trajectory prediction error below approximately 700 km altitude, primarily due to inaccuracies in thermospheric density models. This work presents a method for temporally deconvolving Energy Dissipation Rates (EDRs) to produce single‐satellite density estimates, which can be ...

Identifying and Predicting Coronal Mass Ejection Occurrence: Observational Checklists for Space Weather Forecasters

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Ejections of magnetized plasma from the Sun, known as coronal mass ejections, can drive major geomagnetic activity if Earth‐directed, and are therefore monitored by space weather forecasters. The current focus being the forecast of the arrival time of a coronal mass ejection at Earth and the level of geomagnetic impact.

A Major Update to the PyIRI Model

Space Weather, Volume 24, Issue 6, June 2026.
Abstract This paper presents a major update to the PyIRI model, a fully vectorized Python implementation of the International Reference Ionosphere (IRI). The update reformulates the IRI core coefficients using spherical harmonics in Quasi‐Dipole (QD) latitude and Magnetic Local Time coordinates, replacing the legacy geographic‐coordinate‐based basis ...

Axial length, myopia progression, and myopic maculopathy in Stickler syndrome

Acta Ophthalmologica, Volume 104, Issue 4, Page 423-430, June 2026.
Abstract Purpose We lack knowledge on the potentially progressive nature of and the prevalence of complications to myopia as a characteristic trait of Stickler syndrome. Methods This cross‐sectional study combines ophthalmic examination and medical record data on Danish patients with genetically confirmed Stickler syndrome type 1 (COL2A1) and type 2 ...

Anterior chamber flare and central macular thickness after trabeculectomy versus after phacoemulsification

Acta Ophthalmologica, Volume 104, Issue 4, Page 402-409, June 2026.
Abstract Purpose To compare the inflammatory response in the eye after trabeculectomy to after phacoemulsification, focusing on anterior chamber flare (AC flare) and central macular thickness (CMT). Methods Data from 436 participants in two randomized controlled trials were analysed.
