In this Brief Report it is pointed out that there are three dusk-dawn aberrations of the solar-wind plasma and magnetic structure approaching Earth and the magnitudes of these aberrations are estimated for various solar-wind types monitored from L1. Solar-wind monitors closer to the Earth than L1 would have superior performances.

1) Since the outer electron radiation belt is lost on occasion, the radiation belt needs seed electrons to rebuild. 2) The clear candidate for that seed population is energetic substorm-injected electrons in the dipolar magnetosphere. 3) The energetic substorm-injected electrons in the dipole come from the suprathermal electron population in the ma...

Several machine learning algorithms and feature subsets from a variety of particle and magnetic field instruments on-board the Cassini spacecraft were explored for their utility in classifying orbit segments as magnetosphere, magnetosheath or solar wind. Using a list of manually detected magnetopause and bow shock crossings from mission scientists,...

In this study we analyze the storm-time evolution of equatorial electron pitch angle distributions (PADs) in the outer radiation belt region using observations from the Magnetic Electron Ion Spectrometer (MagEIS) instrument aboard the Van Allen Probes in 2012–2019. The PADs are approximated using a sum of the first, third and fifth sine harmonics. ...

Using numerical experiments, the effects of noise in the solar-wind and magnetospheric data on fits to the data are examined. In particular, the impact of noise amplitude on the functional forms of best-fit solar-wind driver functions is explored. The presence of noise (measurement error) will make it difficult to use solar wind and magnetosphere d...

Systems science is a relatively new way of studying the magnetosphere. This perspective outlines the need for it and how it can contribute to our understanding and so give more reliable forecasts, predictions, and space weather climatologies.

For the first time to solve the problems of laboratory modelling of cosmophysical phenomena of an explosive nature (active experiments of the AMPTE type, with barium injections into the magnetosphere), spherical laser plasma clouds (LPCs) were produced and applied (in experiments at the KI-1 test facility of the ILP SB RAS). Use was made of the cla...

The new findings for dynamic process of inward diffusion in the magnetospheric plasma are reported on the Ring Trap 1 (RT-1) experiment: (i) the evolution of local density profile in the self-organized process has been analyzed by the newly developed tomographic reconstruction applying a deep learning method; (ii) the impact of neutral-gas injectio...
