Transport in the interplanetary medium of coronal mass ejections [PDF]
Geofísica Internacional, 2008 Coronal mass ejections (CMEs) are large scale structures of plasma and magnetic field expelled from the Sun to the interplanetary medium and generally observed in white light coronagraphs.

Space Weather, Volume 23, Issue 8, August 2025.Abstract We present observations of plasma structuring from three meters up to hundreds of kilometers at auroral latitudes during the extreme geomagnetic storm of May 2024 using co‐ordinated observations from ICEBEAR and Global Navigation Satellite Systems (GNSS) receivers. Intense irregularities on all spatial scales co‐existed for about 4 hr between ∼

Analysis of the Consecutive X‐Ray Flares Effects on the Lower Ionosphere
Space Weather, Volume 23, Issue 8, August 2025.Abstract X‐ray is a critical factor in generating electrons in the lower ionosphere, however, the cumulative effects of consecutive X‐ray flares on the lower ionosphere remain understudied due to the scarcity of historical events. From May 8 to 15, 2024, intense solar eruptions occurred, featuring multiple consecutive X‐ray flares.

Interplanetary magnetic fields, their fluctuations, and cosmic ray variations [PDF]
The cause of Forbush decreases is examined using neutron monitor data and measurements of the interplanetary magnetic field. It is found that for the period examined (Dec.

Solar wind disturbances in th outer heliosphere caused by successive solar flares from the same active region [PDF]
, 1983 Solar wind disturbances caused by successive flares from the same active region are traced to about 20 AU, using the modeling method developed by Hakamada and Akasofu (1982).

What happens when the geomagnetic field reverses?
, 2012 During geomagnetic field reversals the radiation belt high-energy proton populations become depleted. Their energy spectra become softer, with the trapped particles of highest energies being lost first, and eventually recovering after a field reversal ...

Unveiling the Global Characteristics of Turbulence in the Venusian Space Environment
Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.Abstract Turbulence plays a crucial role in energy transfer from large to small scales in solar wind‐Venus interaction. Observations have identified magnetic field fluctuations and turbulence in the Venusian space environment. However, due to limited observations and simulation resolutions, neither the global characteristics nor the driving mechanisms ...
