1. AGU Fall Meeting Session PA012: Defining Extreme Space Weather Events
------------------------------------------------------------
From: Seth Jonas (sjonas at ida.org)

On behalf of the conveners, I invite you to submit to the 2016 Fall AGU session: "Defining Extreme Space Weather Events."

The abstract submission deadline is August 3rd. This session is in the in Public Affairs section and therefore may not count against the standard First Author submission limit in the usual way. See below for the detailed description and more information.

PA012: Defining Extreme Space Weather Events
Session ID#: 13854
Section/Focus Group: Public Affairs

Session Description: 
Space weather events have the potential to adversely affect technological and infrastructure systems that millions depend on. Extreme events are often held to the "standard" of the 1859 Carrington-Hodgson event (arguably the most extreme space weather event in recorded history), and the likelihood that an event comparable in magnitude could reoccur. This session will discuss the current capability and research activities for predicting and understanding the effects of such events and the ability to adequately inform industry and policymakers of the risks posed. Questions addressed in this session include:

(1) What are the parameters that define an extreme event?
(2) What measurements are available that provide insight into extreme conditions?
(3) What systems are exposed and what conditions affect their performance?
(4) What is the capability to model extreme event conditions with respect to technological and infrastructure system?
(5) In what areas should new research and measurement capability be directed?

Co-Organized with:
SPA-Solar and Heliospheric Physics

2. AGU Fall Meeting Session SM002: Advancing Cross-disciplinary Knowledge of Ground Magnetic Perturbations: Understanding Sources from the Outer Space to Deep Inside the Earth
------------------------------------------------------------
From: Peter Chi, Mark Engebretson, Carol Finn, Paul Bedrosian (pchi at igpp.ucla.edu)

At the upcoming AGU Fall Meeting, we will hold a cross-disciplinary session on the geospace and earth sources of magnetic field perturbations on the ground. This is a rare opportunity when both geospace and earth aspects in ground-based magnetometer observations are discussed in the same session, facilitating future interpretation of geomagnetic data in a broader geospace-earth framework.

You are cordially invited to participate in this cross-disciplinary session. All abstracts with ground-based magnetometer observations are welcome. Please see below for the detailed session description and submit abstracts by August 3 online at https://agu.confex.com/agu/fm16/preliminaryview.cgi/Session13224.

Thank you and we look forward to seeing you at the Fall AGU in San Francisco,

Session description:

SM002: Advancing Cross-disciplinary Knowledge of Ground Magnetic Perturbations: Understanding Sources from the Outer Space to Deep Inside the Earth

Magnetic field perturbations detected by ground-based magnetometers provide valuable information for a range of research topics in earth and space sciences, such as the electric currents and waves in the magnetosphere and the ionosphere, subsurface electrical conductivity, potentially damaging currents in power grids during severe solar storms, and possibly signals prior to and during major earthquakes. The effects from the outer space to deep inside the Earth could intertwine in the same magnetic field data, posing possible challenges in interpreting observations. As ground-based magnetometer measurements have become network observations, understanding both geospace and earth effects on ground magnetic perturbations is more critical than ever to properly study geospace phenomena and earth’s interior as well as monitor natural hazards with automated algorithms. This session welcomes all relevant geospace and earth studies based mainly on ground-based magnetometer data, including those that can advance our cross-disciplinary knowledge of ground magnetic perturbations.

3. AGU Fall Meeting Session SM003: Advancing our Understanding of the Dynamic Magnetosphere-Ionosphere System Using Auroral Imaging
------------------------------------------------------------
From: Jesper W Gjerloev (jesper.gjerloev at jhuapl.edu)

Dear Colleagues,

We invite you to submit an abstract to our Fall AGU session:

Link to the AGU session SM003: https://agu.confex.com/agu/fm16/preliminaryview.cgi/Session12389.html

Abstract:
Auroral imaging from ground-based instrumentation as well as from space born imagers have led to great advances in our understanding of the Magnetosphere-Ionosphere system but they have also left us with puzzling discoveries.  We now recognize that there are persistently recurring types of auroral forms with characteristic patterns and development.  Examples are north-south aligned arc, PBI’s, omega bands, and auroral beads.
The fact that nighttime aurora exhibit distinct and repeatable forms is remarkable.  The consistent auroral behavior from case to case testifies to a corresponding consistency in the electrodynamics.  As the auroral forms from case to case repeat, even in varying locations, the underlying electrodynamics also repeats.
In this session we invite papers that attempt to provide insight into the role(generation and effect) of these auroral forms for(in) the magnetosphere-ionosphere system.  Theoretical, modeling as well as observationally driven studies are welcome.

Session ID: 13559 
Session Title: SM012: Interaction of mesoscale magnetotail transients with the inner magnetosphere and the ionosphere 
Section/Focus Group: SPA-Magnetospheric Physics
Session Description: Mesoscale magnetotail transients are linked to low-entropy bubbles that originate in the plasma sheet and rapidly move into the inner magnetosphere. Recent in-situ observations from spacecraft such as THEMIS, Van Allen Probes, and MMS, along with improvements in theory and simulations, have produced new insights and outstanding questions about the physical properties of such transients and impacts on the inner magnetosphere. These transients are often observed in the tail and inner magnetosphere, where they are associated with dipolarizing flux bundles, dipolarization fronts, auroral streamers, bursty bulk flows, Pi2 braking oscillations, and energetic particle injections. Such energetic particles are thought to be important to field-aligned currents that close in the ionosphere, the generation of various plasma waves, and a major contributor to the ring current and radiation belt populations. Presentations, both observational and theoretical, are requested that provide new insights into this important and fundamental process.

------------------------------------------------------------
From: Gina A DiBraccio (NASA GSFC), Daniel J Gershman (UMD/NASA GSFC), and Marissa Vogt (Boston U) (daniel.j.gershman at nasa.gov)

We invite contributions to an AGU session entitled "Magnetospheres in the Inner Solar System" scheduled at the 2016 AGU Fall Meeting (December 12-16)

The structure and dynamics of each planetary magnetosphere (intrinsic and induced) in the inner solar system are driven by a unique set of factors including the nature of its magnetization, atmosphere-ionosphere coupling, and local solar wind parameters. To provide a forum for discussion of recent data analysis and modeling efforts concerning the inner planet magnetospheres, this session welcomes submissions on the intrinsic magnetospheres of Mercury and Earth, as well as the induced magnetospheres of Venus and Mars. It will focus on general magnetospheric processes including, but not limited to: solar wind-magnetosphere interaction, magnetosphere-ionosphere coupling, plasma acceleration and transport, magnetic reconnection, wave instabilities, magnetotail dynamics, and bow shock physics. We strongly encourage comparative studies of these inner solar system magnetospheres with each other or with other planetary magnetospheres throughout the solar system.

6. AGU Fall Meeting Session SM020: Magnetotail Dynamic Processes: Recent Progress in Observations and Simulations
------------------------------------------------------------
From: Jiang Liu, Chih-Ping Wang, and Yu Lin (jliu at igpp.ucla.edu)

Dear Colleagues,

We would like to invite you to submit your abstract to AGU session SM020: Magnetotail Dynamic Processes: Recent Progress in Observations and Simulations. As the Session Description says below, we welcome anything related to the magnetotail. The abstract submission is already open and the deadline is 3 August 23:59 EDT. To submit an abstract, please go to this site (https://agu.confex.com/agu/fm16/preliminaryview.cgi/Session13094) and click the orange button “Submit an Abstract to this Session”.

Session Description:

The magnetotail is the major reservoir of the solar wind energy deposited to Earth’s magnetosphere, and the major arena of this energy’s conversion and transport. A significant amount of the conversion and transport (including mass and momentum transports) occurs during dynamic processes. Such processes include the dynamics of thin current sheets, transients (e.g., plasmoids and BBFs), turbulence, waves and their interaction with particles, etc. These processes can be triggered externally by solar wind/magnetosheath/magnetopause changes, or internally within the tail. The processes and their triggers differs dramatically at different tail distances. Due to the fundamental roles of the magnetotail in the entire magnetospheric energy budget, it is important to continuously improve our understanding of the tail dynamic processes. To achieve this goal, this session solicits new findings on the dynamics in the near-earth tail (<30 RE) and mid/distant tail (>30 RE). This session welcomes observations, theories, and numerical modeling/simulations.

7. AGU Fall Meeting Session SM023:  Multiscale Structure and Dynamics of Earth's Dayside Magnetopause:  Results from the First MMS Dayside Season
------------------------------------------------------------
From: John Dorelli, Paul Cassak, Benoit Lavraud, Steven Petrinec (john.dorelli at nasa.gov)

Dear Colleagues:

We invite you to submit an abstract to session SM 023 at the Fall AGU meeting:

SM023:
Multiscale Structure and Dynamics of Earth's Dayside Magnetopause:  Results from the First MMS Dayside Season

NASA's Magnetospheric Multiscale (MMS) mission completed its first dayside season on March 8, 2016.  With a spacecraft separation as small as 10 km, MMS now probes the sub ion-scale structure of Earth's dayside magnetopause, observing the plasma and fields at comparable temporal resolutions for the first time.  Comparison of these observations with simulations has provided many new insights into the structure of the magnetopause boundary layer, including:  the structure of the electron and ion diffusion regions in asymmetric reconnection, the ion-scale structure of reconnection exhausts, the role of secondary islands in the reconnection process, the nature of turbulent fluctuations in the magnetosheath and low latitude boundary layers, the kinetic structure of Flux Transfer Events (FTEs), and the large scale topology of the dayside magnetopause.  We solicit abstracts investigating these and related topics using observations, theory and modeling, and laboratory experiments, with emphasis on relevance to the interpretation of MMS data.
