The solar wind is a magnetized plasma and as such exhibits collective plasma behavior
associated with its characteristic spatial and temporal scales. The characteristic length …

As observed in Thomson-scattered white light, coronal mass ejections (CMEs) are manifest
as large-scale expulsions of plasma magnetically driven from the corona in the most …

A key goal for space weather studies is to define severe and extreme conditions that might
plausibly afflict human technology. On 23 July 2012, solar active region 1520 (~ 141° W …

The Sun, as an active star, is the driver of energetic phenomena that structure interplanetary
space and affect planetary atmospheres. The effects of Space Weather on Earth and the …

Wavelet analysis can be used to measure the power spectrum of solar-wind fluctuations
along a line in any direction (θ, ϕ) with respect to the local mean magnetic field B 0. This …

Context. A complex and long-lasting solar eruption on 17 April 2021 produced a widespread
solar energetic particle (SEP) event that was observed by five longitudinally well-separated …

BepiColombo Mio (previously called MMO: Mercury Magnetospheric Orbiter) was
successfully launched by Ariane 5 from Kourou, French Guiana on October 20, 2018. The …

During propagation, Magnetic Clouds (MC) interact with their environment and, in particular,
may reconnect with the solar wind around it, eroding away part of its initial magnetic flux …

We investigate multi-spacecraft observations of the 17 January 2010 solar energetic particle
event. Energetic electrons and protons have been observed over a remarkable large …

We present a comprehensive statistical analysis spanning over a solar cycle of the
properties and drivers of traveling fast forward and fast reverse interplanetary shocks. We …
