1. Job opening: SHIELD Open Workshop on the Outer Heliosphere, date: June 2 - June 6, 2025.

From: Nick Gross, Boston University, <gross at bu.edu>

Subject: SHIELD Open Workshop on the Outer Heliosphere, August 11-15, Stoweflake Resort, Stowe, Vermont, USA.

SHIELD, a NASA DRIVE Science Center, is organizing an open workshop on all aspects of outer heliosphere science. Voyager 1 and Voyager 2 crossed the termination shock and heliopause, the end of supersonic solar wind flow and the transition from solar wind to interstellar plasma, respectively. Numerical and analytical modeling efforts have increased understanding of the in situ observations and also posed new questions. IBEX and CASSINI ENA observations discovered the ribbon and belt and gave a view of the 3D heliosphere and its time dependence; IMAP will provide even better ENA data. New Horizons is approaching the termination shock and provides new pick-up ion observations. This workshop will discuss all aspects of the outer heliosphere and interstellar medium, including in-situ observations, data analysis, theory, and modeling. The workshop topics include plasma, magnetic fields, pickup ions, dust, UV, and cosmic rays in the heliosphere and beyond.

Details on schedule and registration to follow. Questions can be directed to shieldoutreach at bu.edu.

3. Abstract submission: EGU2025 Call for abstracts ST2.4 - Global magnetospheric dynamics in simulations and observations, deadline: 15 January 2025.

From: Andrey Samsonov, MSSL, UCL, <a.samsonov at ucl.ac.uk>

Subject: EGU2025 Call for abstracts ST2.4 - Global magnetospheric dynamics in simulations and observations.

We would like to draw your attention and invite you to submit an abstract to the ST2.4 session "Global magnetospheric dynamics in simulations and observations" in the ST2-Magnetosphere programme group of the European Geosciences Union (EGU) General Assembly 2025. The General Assembly 2025 of the EGU will be held at the Austria Center Vienna (ACV) in Vienna, Austria and online, from 27 April – 2 May 2025.

Session page: https://meetingorganizer.copernicus.org/EGU25/session/53606.
Please note that the deadline for the abstract submissions is 15 January 2025, 13:00 CET, but those who would like to receive travel support should submit their abstracts before 2 December 2024.

Session description: Large-scale dynamic processes in different magnetospheric regions, e.g., in the magnetosheath, at the magnetopause, in the outer and inner magnetosphere, magnetotail, ring current and plasmasphere are closely interconnected. The magnetosphere should therefore be considered as a global system. The state of the magnetosphere is controlled mainly by solar wind conditions. The interplanetary magnetic field (IMF) and solar wind velocity govern the energy input into the magnetosphere. However, solar wind properties change when plasma moves through the bow shock and magnetosheath. The magnetic reconnection rate at the dayside magnetopause depends on parameters in the surrounding magnetosheath and magnetosphere rather than directly on the solar wind conditions. Once dayside reconnection starts, magnetic flux accumulates in the magnetotail lobes, eventually resulting in substorms or steady magnetospheric convection. Magnetic reconnection in the magnetotail injects thermal and energetic particles into the inner magnetosphere and downward along magnetic field lines into the ionosphere. The Kelvin-Helmholz instability provides another important mechanism of energy and momentum transition from the solar wind into the magnetosphere.

Global magnetospheric dynamics can be studied by means of increasingly sophisticated numerical simulations (MHD, hybrid, or fully kinetic), with empirical and semi-empirical models, or using multipoint in situ spacecraft observations. A fleet of space missions can investigate magnetospheric phenomena in-situ, providing crucial information concerning the positions and dynamics of the magnetospheric plasma boundaries and the global distribution of the magnetospheric plasma and processes within it. Past and future global imaging missions (e.g., LEXI, SMILE, GEO-X, and others) can complete this picture by providing large-scale snapshots of some geospace regions. Accurate modelling of global magnetospheric processes is an essential condition for successful space weather predictions, but sometimes model predictions are very different from each other even for typical solar wind conditions. We welcome any work presenting results on the global dynamics of the Earth’s magnetosphere as well as the magnetospheres of other planets.

4. Conference: Briefing meeting in advance of next Call for Medium and Fast missions and of an exploratory call for mini-F proposals in the ESA Science Programme, registration: on 4 December 2024.

From: Matthew Taylor, SCI-EP, ESTEC, European Space Agency, <Matthew.Taylor at esa.int>

Subject: Briefing meeting in advance of next Call for Medium and Fast missions and of an exploratory call for mini-F proposals in the ESA Science Programme.

In order to maintain diversity, flexibility, and proper cadence of missions in the Science Programme, the ESA Director of Science plans to issue, in March 2025, a Call soliciting the scientific community in ESA's Member States for proposals for both a Medium-class mission opportunity (M8; to be launched around 2041) and a Fast-class mission opportunity (F3; to be launched around 2034). At the same time, an exploratory Call will also be issued soliciting proposals for a new type of agile mission, referred to as mini-Fast missions.

An online briefing to prospective proposers will be held on 11 December 2024, to provide any necessary clarification on the scope of the proposals, the expected information, possible international cooperation schemes, possible payload provision schemes, etc. Prospective proposers should register for the online briefing in advance.

Registration for the workshop will open on 4 December 2024 at this website:

5. Conference: 3rd Machine Learning in Heliophysics (ML-Helio) conference, date: 22-26 September, 2025.

From: Matthew Taylor, SCI-EP, ESTEC, European Space Agency, <Matthew.Taylor at esa.int>

Subject: 3rd Machine Learning in Heliophysics (ML-Helio) conference

When: 22-26 September, 2025

Where: European Space Agency (ESA), ESAC (European Space Astronomy Centre), Madrid, Spain. 

The goal of the ML- Helio conference is to leverage the advancements happening in disciplines such as machine learning, deep learning, statistical analysis, system identification, and information theory, in order to address long-standing questions and enable a higher scientific return on the wealth of available heliospheric data.

We aim at bringing together a cross-disciplinary research community: physicists in solar, heliospheric, magnetospheric, and aeronomy fields as well as computer and data scientists. ML- Helio will focus on the development of data science techniques needed to tackle fundamental problems in space weather forecasting, inverse estimation of physical parameters, automatic event identification, feature detection and tracking, times series analysis of dynamical systems, combination of physics-based models with machine learning techniques, surrogate models and uncertainty quantification.

The conference will consists of classic-style lectures, complemented by hands-on tutorials on Python tools and data resources available to the heliophysics machine learning community.

The conference will be hosted in hybrid mode (in-person and virtual).

More information will be posted soon on: https://ml-helio.github.io/

6. Abstract submission: second announcement international international workshop on 'particle acceleration and transport: from the sun to extragal'.

Abstract submission and registration are now open at

http://astroplasmas.unical.it/workshop2025/index.php?link=1#sottotitolo

Deadlines:

Review and Invited talks abstract submission: December 15th, 2024

Contributing talks abstract submission: January 8th, 2025

Early bird registration (at the cost of 280 euros): December 31st, 2024

Normal registration (at the cost of 330 euros): from January 1st, 2025 to January 26th, 2025

Scientific rationale: 

This workshop aims at presenting recent research on the longstanding problems of particle acceleration and transport in different astrophysical environments, such as the Sun, the heliosphere, galactic sources, and extragalactic sources. The purpose is to bring together experts in the fields of cosmic ray physics, plasma turbulence, acceleration processes, and particle transport, in order to stimulate cross-fertilization and to exchange scientific information among different areas. Indeed, the basic theoretical framework adopted to describe particle acceleration and transport is common to all those fields but the properties of the environments change noticeably. In addition, in-situ and remote observations often question the validity of the standard theories and call for further investigations. The availability of large datasets from new instrumentation and recent theoretical and numerical studies give the opportunity to advance the models and possibly to answer some of the basic unresolved issues. Exchange of ideas among the various fields would certainly speed up this process.

We strongly encourage to present recent, pioneering observations, theories, and models that try to explain and describe processes of particle acceleration and transport. We try to bring together scientists who would like to understand what is happening beyond their field of specialty.

Main Topics: 

Observations of energetic particles in the solar, heliospheric, galactic and extragalactic environments

Properties of cosmic ray transport and acceleration from in-situ and remote observations

Solar flares, Crab flares, flaring phenomena in astrophysics

From: Martin Archer, Imperial College London, <m.archer10 at imperial.ac.uk>

Subject: Research Associate in Mega-Constellation Space Physics at Imperial College London, UK

The rise of satellite mega-constellations in low Earth orbit is unlocking the possibility of ubiquitous global monitoring of our planet. This Research Associate in Mega-Constellation Space Physics will explore the potential of harnessing mega-constellations for monitoring the solar wind – magnetosphere – ionosphere interaction to advance space weather science and operations.

By becoming a key member of the exciting UKRI Future Leaders Fellowship project “Harnessing mega-constellations to probe space weather globally” in the Department of Physics at Imperial College London (UK), you will undertake original research exploring how satellite mega-constellation could dramatically improve upon current capabilities. You will develop global spatiotemporal fitting and data assimilation methods for mega-constellation magnetic field observations to unveil the dynamic magnetosphere – ionosphere current systems present. These methods will be tested using Imperial’s global magnetospheric simulations to understand the capabilities of current and future satellite constellations for space weather operations and science. Ultimately the methods will be applied to data collected from Eutelsat OneWeb’s Gen1 mega-constellation of over 630 satellites to advance our current scientific and operational capabilities in space weather. Through this work you will not only set new directions for space missions and satellite operators, but also improve our understanding of the dynamics of the solar wind – magnetosphere – ionosphere interaction in general.

We are looking for people with knowledge of the solar wind – magnetosphere - ionosphere interaction, and practical experience in a broad range of techniques including satellite observations, computer simulations, or theoretical analysis.
