2. SESSION: AGU 2017 - Heliospheric Sessions
SH013: "Facing and Understanding Particle Radiation in Expanding Human Access to Space"
We invite submissions to the following AGU session (submission deadline Wed Aug 2)
Session Description: Human access to space is expanding in a new realm of deep space exploration, space tourism and the society’s increasing reliance on rapid and reliable aviation. Particle radiation poses significant hazards for astronauts, satellites, aviators and passengers as well as produces affects on planetary bodies. Increasing galactic cosmic ray fluxes near successive solar minima highlight the increasing radiation hazard. Radiation weathers the regolith of the Moon, the two moons of Mars, other airless bodies, and contributes to chemical evolution of atmospheres at Earth, Mars, Venus, Titan, and Pluto. Radiation remains a factor that we must face through improved understanding and innovation of methodologies for prediction. We invite abstracts on research including the origin of SEPs from coronal mass ejections, propagation of events through the solar system during the anomalously weak solar cycle 24 and important examples of radiation interactions for Earth, other planets and airless bodies such as the Moon.

SH014: "Connectivity between Solar Energetic Particle sources and in-situ Particle Observations"
We invite submissions to the following AGU session (submission deadline Wed Aug 2)
Session Description: Solar Energetic Particle (SEP) sources are usually identified with solar eruptive phenomena such as solar flares and coronal mass ejections (CMEs). To identify these sources correctly, it is necessary to (1) understand the complex connectivity of the solar corona to 1 AU and (2) unambiguously determine the particle release times that are consistent with the in-situ SEP measurements. Several diverse techniques have been proposed to address these points but they do not always provide consistent results. We encourage presentations that use remote and in-situ observations, simulations, and theory, to determine the properties of SEP sources and establish their connectivity with particle observations, paying special attention to studies using multi-spacecraft observations and those that might take advantage of future near-the-Sun observations from Solar Probe Plus and Solar Orbiter.
Conveners: David Lario (JHU/APL), Ian G Richardson (NASA/GSFC), and RyunYoung Kwo (George Mason Univ.)
SH021: "Velocity Space: The Final Frontier"
Session Description: In weakly collisional space plasmas, such as the solar corona and solar wind, velocity space contains a wealth of information regarding the dynamics of the system. Using physics-based models to interpret the fluctuations in velocity space opens up novel means of identifying the physical mechanisms governing plasma heating and particle energization, a key goal of heliophysics. This session will highlight innovative new diagnostic techniques and analysis methods that are being developed to utilize fully the information contained in velocity space, including field-particle correlations, transformation and analysis of velocity-space structure using Hermite, Hankel, or other orthogonal basis sets, and studies of the quasilinear evolution of the velocity distribution function. Experimental, analytical, and numerical investigations that exploit particle velocity distribution function measurements in weakly collisional or collisionless plasmas are solicited. Kristopher Klein, Jason TenBarge, Gregory Howes
SH022: "Statistical Mechanics and Distributions in Space Plasmas"
Session Description: Space plasmas are collisionless particle systems with correlations and cannot be described by elements of the standard Boltzmann-Gibbs statistical mechanics. Instead, the generalized framework of non-extensive statistical mechanics is used, with tremendous implications and applications in space plasmas. We welcome abstracts reporting on the progress of the following three broad subject areas: (1) Theoretical foundations: non-extensive statistical mechanics; kappa distributions; connection with thermodynamics; entropy and information measure; concept of temperature; and distributions with potential energy or anisotropies. (2) Effects on Plasma Processes, Dynamics, and Complexity: particle acceleration; transport and diffusion; plasma linear/nonlinear waves and instabilities; shocks and Rankine–Hugoniot conditions; polytropic relations; plasma interactions; particle correlations; coupling phenomena; turbulence and chaos; and mechanisms generating kappa distributions. (3) Data Analyses, Simulations, and Applications: solar / stellar atmospheres; flares / CMEs; solar wind; ionosphere; terrestrial, planetary, and cometary magnetospheres; heliosheath, interstellar plasmas, and beyond.
SH026: "Observing the Evolving Global Heliosphere over the Solar Cycle with IBEX and INCA"
We invite submissions to the following AGU session (submission deadline Wed Aug 2)
Session Description: The Interstellar Boundary Explorer (IBEX) and the Ion and Neutral Camera (INCA) instrument on Cassini globally image the solar wind's (SW) interaction with the local interstellar medium (LISM) by detecting energetic and lower energy neutral atoms that are created from and beyond heliospheric boundary regions. These observations provide a wealth of knowledge as the heliospheric environment evolves through the unique solar cycle 24, an era of activity unlike any other observed in the space age. We invite abstracts focusing on understanding the interaction of the SW with the LISM, the evolution of the global heliosphere, the properties and composition of the heliosheath and interstellar plasma, the processes causing particle acceleration due to solar and interstellar interactions, and the connections between IBEX, INCA and Voyager's in situ measurements of heliospheric boundary regions and the LISM. These observations form the bases of a new chapter of exploration of our local galactic environment.
Primary Convener: Nathan Schwadron (University of New Hampshire, Durham)
Convener: Stamatios Krimigis (Johns Hopkins University Applied Physics Laboratory)
Convener: Eric Zirnstein (Princeton University)
Invited Speakers: David J. McComas (Princeton University), Kostas Dialynas (Academy of Athens)
SH027: "Physical Phenomena in the Outer Heliosphere and Beyond"
Session Description: The Voyager 1/2 mission is performing in situ investigation of the physical phenomena that accompany the solar wind interaction with the local interstellar medium. In partially ionized plasmas, charge exchange, ionization, kinetic and fluid instabilities, and magnetic fields play important roles in determining the heliospheric structure. This session addresses the most challenging issues related to Voyager observations: (1) the effects of charge exchange, interstellar magnetic field draping, and time dependent phenomena on Voyager observations; (2) physics of non-thermal ions; (3) ion acceleration at the termination shock and in the heliosheath; (4) galactic cosmic ray transport throughout the heliosphere and LISM; (5) roles of plasma waves, turbulence, instabilities, and magnetic reconnection; (6) relation of Voyager measurements to remote observations from IBEX, Cassini, SOHO, HST, and air shower observatories. We solicit papers addressing these and other phenomena occurring in the outer heliosphere and LISM.
Primary Convener: Nikolai V Pogorelov, University of Alabama in Huntsville, United States

INVITED SPEAKERS: Edward Stone (Caltech) and Vlad Izmodenov (Space Research Institute, Moscow)
SH028. "The Local Interstellar Medium and its Interaction with the Heliosphere"
Session Description: The very local interstellar medium (VLISM) just beyond the heliosphere has received considerable recent interest. Voyager 1 is likely now making the first in situ measurements in the VLISM. Remote observations, such as energetic neutral atoms, galactic cosmic-ray anisotropies, and Lyman-alpha spectroscopy also provide new insights. Interpretation of the new observations presents a challenge. The VLISM is a combination of the pre-existing large-scale turbulent interstellar medium, and transient disturbances from the heliosphere. This includes a few events recently observed by Voyager 1 that will likely continue. The fluctuating solar wind, currently measured in situ by Voyager 2 and others, likely also influences the VLISM. The goal of this session is to highlight the new observations and bring together theorists and numerical modelers whose recent work brings fresh insights into the physics of the VLISM. We welcome abstracts in all the above and related areas.
Conveners: J. Giacalone, A. Cummings, and J. R. Jokipii
SH030: "The Interstellar Probe Mission: Drivers, Definition and Implementations for Embarking on Interstellar Voyages Before 2050"
Session Description: As the Voyagers are crossing in to the Interstellar Medium and the Kepler Mission has unveiled an abundance of Earth-like planets around other Suns, inevitably, we are faced with the question of how, why and when humanity will venture out through the vast space between our star and other potentially habitable planetary systems. This session welcomes presentations on the scientific, technological and sociological drivers and implementations for embarking on interstellar exploration before 2050. It seeks contributions from all disciplines on groundbreaking scientific targets including the local interstellar medium, the undiscovered worlds of the Kuiper Belt, the structure of the circum-solar dust disk, astrophysical/exoplanetary observations enabled by the solar gravity lens, the Oort Cloud and beyond. Presentations on enabling technologies in power, communication, lifetime, propulsion and instrumentation should form a significant part of the session. Presentations on programmatic challenges and possible implementations are also desired.

3. SESSION: AGU 2017 - Magnetospheric Session
SM012: "Plasma Energization during Collisionless Magnetic Reconnection"
Session Description: Jet formation, plasma heating, and particle acceleration are important and common processes during magnetic reconnection in collisionless systems, which can range from Earth's magnetosphere to possibly the black-hole accretion disk at the center of the Milky Way. Recent instrumental and computational advances have enabled new frontiers of research regarding these energization processes. The session invites contributions that will expand our understanding of how and where electrons and ions are energized, and how dissipated magnetic energy is partitioned among various plasma species/components. Of immediate interest are the effects on energization due to the reconnection and in-plane electric fields, parallel electric field, wave fluctuations, etc., and how the guide field and upstream conditions influence the energization and energy partition. Studies integrating new results from magnetospheric/heliospheric missions and kinetic simulations/theories are particularly encouraged.

4. WORKSHOP: Space Weather: a Multi-Disciplinary Approach, Leiden, The Netherlands, September 25-29, 2017
From: Enrico Camporeale (e.camporeale at
cwi.nl)
SCOPE and AIM: The study of space weather has traditionally been carried out using standard techniques and tools found in space physics such as time series correlational analyses. These techniques, although having the advantage of being fast and simple, are sometimes not adequate or complete because the Sun-Earth system is a complex nonlinear system. On the other hand, researchers in the fields of mathematics, information science, computer science, machine learning, data mining, have developed, over the last several decades, tools that can handle complex nonlinear systems and are eager to apply these new tools to new difficult problems.
The aim of this workshop is to bring together researchers from space weather, space physics, mathematics, computer science, information science, machine learning, data mining, etc. to foster symbiosis and cross-fertilization across the fields.
The topics that will be discussed include:
-- machine learning for Space Weather
-- information theory for Sun-Earth system
-- pattern recognition and deep learning of solar images
-- data mining in space physics
Please notice that the workshop is limited to 45 participants. Lorentz Center workshops have no registration fees. Hotel accommodation can be arranged through the Lorentz Center. Please contact the organizers for further information. Enrico Camporeale,
