We invite contributions to the session “Sources for Suprathermal Ions” (https://agu.confex.com/agu/2018tess/preliminaryview.cgi/Session40387)
at The Triennial Earth–Sun Summit that will be held on May 20-24, 2018 at the Lansdowne Resort and Spa in Leesburg, VA, USA (https://connect.agu.org/tess2018/home).

Session Description:
Suprathermal ions (ions of a few times the solar wind plasma energy up to 100s of keV per charge) are known to play a significant role as the seed population in the acceleration to high energy particles by coronal mass ejection (CME) shocks. In the quest for a reliable prediction of the properties of large solar energetic particle (SEP) events, one crucial element is a quantitative understanding of how the suprathermal particles are produced and distributed in the solar corona and the solar wind, especially as a sustained source. Another crucial element is a quantitative understanding of how the variation in the suprathermal seed population contributes to the variation in SEP properties. This session invites contributions from theories, models and observations that aim toward this aspect of research.

Session conveners: Yuan-Kuen Ko (yuan-kuen.ko@nrl.navy.mil), George C. Ho (George.Ho@jhuapl.edu), Nariaki Nitta (nitta@lmsal.com)

Dear Colleagues,

We wish to invite you to participate in COSPAR event D1.1, which will be held in in Pasadena, California, USA, on 14-22 July 2018. This event is organized by Scientific Commission D – Space Plasmas in the Solar System, including Planetary Magnetospheres – within the COSPAR Scientific Assembly 2018.

An increasing number of observations show that anisotropic energetic particle distributions are ubiquitous in the heliosphere. Examples include solar energetic particles escaping from solar flare sites and those propagating in front of traveling shocks, galactic cosmic rays at Earth, Jovian electrons, and termination shock particles. Among the compelling problems in astrophysics there are the mechanisms of particle acceleration and transport. However, a number of observations do not fit into the standard diffusive shock acceleration scenario, and transport processes different from normal diffusion, i.e., superdiffusion and subdiffusion, are becoming commonly recognized in space plasmas. Energetic particle acceleration is influenced in a fundamental way by the particle anisotropy and the transport properties. The above processes cannot be described with the standard Parker transport equation: While a treatment of anisotropy requires solving the Skilling equation, anomalous diffusion can be addressed on the basis of fractional differential equations and non-Gaussian stochastic processes. Further, a high energy density of accelerated particles, as is expected for both supernova remnant and coronal mass ejection shocks, can create self-generated turbulence and modify the shock structure, leading to nonlinear shock acceleration models.

The influences of particle anisotropy, anomalous transport processes and nonlinear effects on shock acceleration require a revision of the standard models of transport and diffusive shock acceleration, which can be achieved by theoretical and numerical studies. From these, direct comparisons with space and ground based observations can be pursued. Therefore, this event aims at shedding light on: (i) particle acceleration at shock waves; (ii) origin and effects of particle anisotropy; (iii) causes and consequences of anomalous particle transport.

This event addresses both the heliospheric and the astrophysical communities. Contributions of theoretical, numerical, and data analysis studies on the above topics are encouraged.

Dear colleagues,

We are pleased to announce the following session at the 42nd COSPAR Scientific Assembly, Pasadena, California, July 14–22, 2018:

Session E2.1: “Formation, destabilization, and ejection of magnetic structures in solar and stellar coronae”

Magnetic structures ejected from the Sun and solar-like stars are typically associated with prominences, which may play critical roles in the initiation of coronal mass ejections (CMEs). In this two-part session, we focus on different aspects of prominences. In the first part, we consider issues regarding the formation and destabilization of prominences. For example, is mass loading important for CME initiation, or for pre-conditioning the CME? In the second part of the session, we focus on the role of the ejected prominence material, particularly its cool component, in the CME evolution: How does the environment of the corona through which the ejected material travels affect the kinematics and deformation of the CME? What is the nature of the energy balance? What is the role of the overlying and CME (flux rope) magnetic topology?

Thanks to the wealth of observational data from multiple viewpoints, over a wide range of wavelengths and heliocentric distances, as well as recent progress in simulations, many of these issues can now be addressed. The three half-day session invites observational studies, as well as simulations of how prominences, and CMEs erupt and interact with their environment in solar and stellar coronae, on a wide range of topics, including:
1. Filament formation and structure: channels, mass
2. Prominence/filament dynamics
3. Eruptions and CMEs
4. CMEs and stellar coronae

Solar Eruptions and their Heliospheric imprint (co-organized)

Convener: Erika Palmerio
Co-Conveners: David Barnes, Athanasios Papaioannou, Jingnan Guo, Neus
Agueda, Luciano Rodriguez

Session Abstract:

The Sun dynamically modifies the conditions of the heliospheric environment, with its pressure-driven solar wind (SW) outflow and solar eruptive events, such as solar flares (SFs) and Coronal mass ejections (CMEs), which are the major drivers of space weather effects at the Earth. The magnetic structure and plasma properties of CMEs, as well as their arrival times at L1, however, are hard to predict with reasonable accuracy. In recent decades, advanced instrumentation onboard many spacecraft has extended our ability to explore structures in the SW, such as interplanetary CMEs (ICMEs) and co-rotating interaction regions (CIRs), as well as solar energetic particles (SEPs) from multiple vantage points throughout the heliosphere. It is now also possible to measure and quantify the radiation environment on different planets and to observe Forbush decreases (FDs). The combination of remote sensing, in-situ and ground based observations has led to the development of models that couple solar eruptive events to their effects on a heliospheric scale. Missions including MESSENGER, Venus Express, STEREO, SOHO, Wind, ACE, MAVEN, Rosetta, Ulysses, INTEGRAL, GOES and ground based measurements from Earth (neutron monitors) and Mars (Mars Science Laboratory), coupled with the imminent launches of Solar Orbiter and Parker Solar Probe, as well as potential future missions at L1 and L5, mean it is an opportune time to showcase current developments dealing with such multi-point studies.

Accordingly, we invite abstracts addressing the following topics: multi-point observations of SEPs with regards to their angular distribution, as well as their injection, acceleration, propagation and transport conditions; the latest observational and modeling efforts of the propagation and evolution of ICMEs in the heliosphere; and the use of such ICME properties for the identification of their effects on magnetospheres and on the ground, such as FDs. We welcome contributions on observations, modelling and theory of the SW, CMEs (ICMEs), CIRs, SFs, SEPs and FDs.

Dear colleagues,

We invite abstract submissions to our session at the 2018 European Geosciences Union General Assembly, “The Use of Observations and Models to Improve Space Weather Forecasting Capabilities in the Heliosphere”, with invited speakers including Emilia Kilpua (Helsinki) and Nina Dresing (Kiel).

The deadline for abstract submission is 13:00 CET on 10th January 2018 (2 days time!). The conference will be held on 2018 April 8-13 in Vienna, Austria. Details of the conference and our session (ST 4.3), as well as others, can be found here: http://meetingorganizer.copernicus.org/EGU2018/session/27199

Session Abstract:

Severe space weather events can significantly impact human technology on the ground and in near-Earth space. Huge eruptions of plasma and magnetic field, known as coronal mass ejections (CMEs), often co-occur with solar flares and can cause problems for a wide variety of industries, such as satellites, radio communications and electricity networks. Solar flares and CMEs also accelerate solar energetic particles (SEPs), which in turn can harm electronics and be a significant radiation hazard to humans outside of the protective shield of the atmosphere. There is significant interest from end users in government and industry to improve the current forecasting methods of these events to mitigate against such risks. Spacecraft observations can be used to forecast when a CME might erupt, track the CME through the heliosphere, to predict the solar wind from another location in space, or to directly probe the different structures and their properties via in situ measurements. Alternatively, models can be developed to simulate solar magnetic fields, to predict where a CME might pass through the heliosphere, and to model its shape and its influence on the magnetosphere. We invite abstracts on both observations and modelling of space weather hazards, including CMEs, the solar wind, co-rotating interaction regions, solar flares, and SEPs.
