Description
This session welcomes submissions on topics not covered under the remaining sessions. These submissions can be on any topic as long as they relate to Space Weather and Space Climate.
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. Here we present a comparison of the Dst and SYM-H global geomagnetic indices with local disturbance data from six stations in southern Europe over the period 1981-2021....
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’...
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...
This poster presents the ongoing ISSI Team project "Beryllium-10 for Earth and Solar Tracing" (BEST), focused on refining the use of the cosmogenic isotope Beryllium-10 (¹⁰Be) as a quantitative proxy for past solar activity and space climate. Beryllium-10 is produced in the atmosphere by cosmic rays interacting with nitrogen and oxygen atoms. It is subsequently deposited and preserved in...
The BiRaKos project (Very Long-Range Bistatic Radar for Space Object Monitoring) aims to develop the concept and initial model of a bistatic radar system for monitoring space objects, with a strong focus on advanced signal processing methods.
The project's core objectives include the design of signal processing techniques using, in the project's initial phase, the data recorded by the LOFAR...
As part of the EMC working group activities on prospective M-class missions, a series of Spacecraft-Plasma Interaction Software (SPIS) simulations were run in various relevant environments for both Plasma Observatory and M-Matisse to evaluate the effect spacecraft charging and accommodation affect plasma payload performance, with some of the results of which can be showcased here
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,...
The Geomagnetism Area of the Instituto Geográfico Nacional (IGN) of Spain conducts a real-time monitoring of several geophysical parameters with the aim of detect and analyse geomagnetic storms. By releasing a series of reports on the most severe geomagnetic storms of recent times, the Area is reaffirming its commitment to space weather research. This poster presentation serves as an...
Solar activity, space weather, extreme meteorological events, global warming, earthquakes, geomagnetic field secular variations all leave their imprint on the lower ionosphere and thermosphere (LIT), this complex interface where neutral atmosphere and space environment interact.
The objective of the original "International Meridian Circle Program (IMCP)", a proposal for an international...
We present work carried out during the joint Bulgarian-Austrian research project on solar chromospheric and coronal activity. The aims of the project are to develop observing capability in Bulgaria to complement Austrian monitoring instruments, and to study chromospheric signatures of quiet sun and pre-eruptive active regions and multi-wavelength manifestation of solar eruptive phenomena,...
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...
The NOAA National Centers for Environmental Information (NCEI) maintains one of the most significant repositories of environmental data in the world, and plays a crucial role in providing access to vital space weather data and products. NCEI empowers scientific discovery, enhances operational capabilities, and contributes to a more resilient society in the face of space weather challenges....
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...
The South African National Space Agency (SANSA) operates a 24/7 Regional Space Weather Centre that was established in November 2022. South Africa through SANSA has been designated by the International Civil Aviation Organisation (ICAO) as a Regional Space Weather Centre in 2018. The role of a Regional Centre is to support the four ICAO Global Centres in the provision of space weather...
The availability of clean measurements of relativistic electrons is an important aspect of space radiation predictions as provided by the REleASE forecasting method. The system makes short-term predictions of the incoming flux of several tenths of MeV protons. The SOlar and Heliospheric Observatory (SOHO) was launched in December 1995 with the Electron Proton Helium INstrument (EPHIN)...
The recently expanded fleet of heliospheric spacecraft presents unique opportunities for exploring solar eruptive phenomena such as coronal mass ejections (CMEs) and solar energetic particles (SEPs) from multiple vantage points. However, the task of integrating diverse observations collected by different instruments across various spacecraft poses a notable challenge. To maximize the...
