Interaction of Coronal Mass Ejection (CMEs) with High-Speed Streams (HSSs) could alter their plasma and magnetic field properties. The properties of the interaction should be encoded in the in situ plasma and magnetic field observations. To characterise the properties of the interaction, we analyse the in situ signatures of 30 interplanetary coronal mass ejections (ICMEs) interacting with...

Forbush decreases (FDs) are one of the very common in-situ signatures of interplanetary coronal mass ejections (ICMEs) throughout the heliosphere. These short-term reductions in the galactic cosmic ray flux are measured by ground-based instruments at Earth and Mars, as well as various spacecraft throughout the heliosphere (most recently by Solar Orbiter). We recently developed an analytical...

Due to geomagnetic dipole tilt, the solar zenith angles and the resultant ionospheric conductivities at the same geomagnetic (GM) latitude and local time are highest in the tilt direction, which are the North American sector in the northern hemisphere and the Australian-New Zealand sector in the southern hemisphere. As a result, the geomagnetic disturbances at observatories in the tilt...

Geomagnetic storms are phenomena that pose a hazard to electronic devices on the earth’s surface. Accurate knowledge of the disturbance conditions of the Earth’s magnetic field is crucial to mitigate potential adverse effects.

Space weather can adversely affect the operation of satellites in Earth orbit and consequently exacerbate the problem of debris generation in space. The associated effects are more probable around the peak of a solar cycle. As we approach the peak of the 25th solar cycle, we leverage on our institute’s cross-program capabilities in model-driven assessment and prediction of LEO objects’...

Gwendal HénaffOPS - Open parallel session (OPS)Poster
From missions such as DMSP / SSJ-5 to MMS / FPI, plasma instruments have been a cornerstone of space weather research. With ever-improving performances, the top-hat concept has been widely used, either as a stand-alone analyzer or coupled to a time-of-flight chamber to provide composition measurements.
However, with its field of view (FoV) confined to the azimuthal plane, the top-hat cannot...

The publicly available data of the Energetic and Relativistic Nuclei and electron Experiment (ERNE) aboard the Solar and Heliospheric Observatory (SOHO) currently extends to ∼100 MeV for protons. However, the instrument has some channels that primarily respond to high-energy protons (hundreds of MeVs) that have so far neither been calibrated nor released. Within the EU Horizon Europe project...

Dynamic spatiotemporal variations in the electrical currents flowing in the ionosphere and near-Earth space result in rapid fluctuations in the time derivative of the geomagnetic field at ground level. Given the conductive nature of the ground, geomagnetic induction generates a geoelectric field capable of inducing an undesired current when aligned with a large-scale conductor on the ground,...

Solar storms are space weather phenomena that can impact critical infrastructure both in space and on the ground, astronauts’ health, and the Earth’s environment. Gaining more knowledge about them is necessary to improve the monitoring, predictions, and risk management of space weather. Coronal Mass Ejections (CMEs) can induce geomagnetic storms, enhancing the auroral oval. Solar flares can...

Geomagnetic indices are essential tools to characterize the effect of solar activity in the Earth’s magnetosphere. The K index, in use for decades, provides a normalized local measure of geomagnetic disturbance over three-hour intervals. However, its limited temporal resolution constrains its applicability for short-term studies and real-time monitoring. To overcome this limitation, one-minute...
