Space Weather, Volume 23, Issue 4, April 2025.Abstract The space weather event on 10–11 May 2024 was a high‐impact geomagnetic storm, resulting in a SYM‐H index decrease to −518 nT, the lowest level registered in several decades. We investigated the response of the Earth's ionosphere during the main phase of this storm using a comprehensive data set of ionospheric observations (in situ plasma ...

An Evaluation of Equatorial Perturbation Electric Fields Using Empirical Vertical Drift Models
Space Weather, Volume 23, Issue 4, April 2025.Abstract We examined the electrodynamic impact of four geomagnetic storms of increasing intensities on the equatorial ionosphere: a moderate storm (27–28 September 2017), a strong storm (17–18 April 2002), a severe storm (07–08 September 2017), and an extreme storm (09–10 November 2004).

Mercury’s Bow Shock and Magnetopause Variations According to MESSENGER Data
UniverseUsing data from the MESSENGER spacecraft magnetometer that describes the magnetopause and the bow shock crossing points of the Mercury’s magnetosphere, we have calculated the parameters of the paraboloids of revolution approximating the obtained points ...

What Is the Lowest Latitude of Discrete Aurorae During Superstorms?
Space Weather, Volume 23, Issue 4, April 2025.Abstract From a survey of published accounts of visual sightings of aurorae, a compilation is presented of the lowest identified geomagnetic latitude at which discrete aurorae were seen at local zenith during magnetic storms having intensities with maximum −Dst>200 ${-}Dst > 200$ nT. The compilation includes data for the superstorms of 2 September 1859,

NAIRAS Version 3 Atmospheric Ionizing Radiation Validation: Comparisons to RaD‐X Measurements
Space Weather, Volume 23, Issue 4, April 2025.Abstract The Nowcast of Aerospace Ionizing RAdiation System (NAIRAS) model predicts dosimetric and radiative flux quantities for assessing human radiation exposure levels and radiation effects on flight electronic systems from the surface of the Earth to deep space. NAIRAS version 3 includes many updates and improvements to the model.

Different Faces of the Martian Magnetosphere
Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.Abstract The Martian magnetosphere contains components of the induced and intrinsic magnetospheres. Since we can not get a global snapshot of the magnetosphere we use a statistical picture based on a large number of measurements. Depending on the choice of coordinate system and the data selection we can observe different faces of the Martian ...

Coherent radio emission from 'Main-sequence Radio Pulse emitters': a new stellar diagnostic to probe 3D magnetospheric structures [PDF]
arXivMain-sequence Radio Pulse emitters (MRPs) are magnetic early-type stars that produce coherent radio emission observed in the form of periodic radio pulses. The emission mechanism behind is the Electron Cyclotron Maser Emission (ECME). Amongst all kinds of magnetospheric emission, ECME is unique due to its high directivity and intrinsically narrow ...
