MEETING: Pencil Code (a high-order finite-difference code for compressible MHD) Meeting in Graz/Austria, 8 - 12 August 2016

From: Philippe-A. Bourdin (pc16 at Bourdin.ch)

The Pencil Code meeting addresses to everyone interested in or using the Pencil Code. We usually hold scientific presentations together with technical discussions. For the first time, we will offer also hands-on sessions for beginners. You get into contact with experts from diverse fields of Astrophysics, Solar physics, and Space research, mainly doing magneto-hydrodynamic (MHD) simulations, some using particles or chemistry in hydrodynamics.

The registration is free of costs. Graz has several UNESCO cultural heritage sites and lies in the south of the Alpes mountains. The venue is the Space Research Institute (IWF) of the Austrian Academy of Sciences. Please submit you registration and find further details here:

SESSION: SHINE 2016 Session "The Origin of Non-Eruptive Large Flares": Call for Abstracts

From: Xudong Sun (xudong at sun.stanford.edu)

shinecon.org/shine2016/session2016.php#session19

In this year’s SHINE workshop session “The Origin of Non-Eruptive Large Flares”, we solicit discussions focusing on the conditions that determine whether large flares are eruptive (i.e. associated with a CME) or non-eruptive. Questions of particular interest include:

— What are those conditions and can we predict them based on photospheric magnetograms and other observations?
— Are different initiation and energy dissipation mechanisms responsible for eruptive and non-eruptive flares?
— How can we effectively compare results from theoretical, numerical, laboratory and observational works?

We welcome poster presentations as well as contributions to the discussion (Tuesday morning, July 12th). Our invited scene-setting speakers will provide brief reviews on observations, numerical modeling, and laboratory experiments. The abstract deadline for poster presentations is June 9th. Please contact the conveners if you like to present 1-2 slides at the discussion.

Conveners: Xudong Sun, Tibor Torok, & Nariaki Nitta

SESSION: SHINE 2016 Session "Coronal magnetic field in the context of the spatial and temporal behavior of SEP events"

From: Nariaki Nitta (nitta at lmsal.com)

http://shinecon.org/shine2016/session2016.php#session3

It is widely agreed that the coronal magnetic field is of critical importance in understanding many phenomena that originate from the Sun.  We have organized a session at this year’s SHINE Workshop to actively discuss the current state of coronal magnetic field observations and modeling.  We will focus on the following questions: how are current observations and modeling used to compute key parameters in heliospheric events, and how can we improve our understanding with existing and/or future data and tools.

The proposed session was motivated by solar energetic particle (SEP) events that were observed at widely separate longitudes in the heliosphere rather quickly after the eruption (e.g. the “circumsolar” SEP event on 3 November 2011).  Making further progress on our understanding of these wide-longitude events will rely on a more sophisticated use of magnetic field data and modeling.  The five most recent SHINE Workshops hosted sessions that discussed closely related topics. This year our focus is on the coronal magnetic field as it relates to both SEP and non-SEP topics.
If you have an interest in any aspects of the coronal magnetic field such as measurement, modeling, application, etc, please attend our session. The invited scene-setting speakers will introduce the current state of coronal magnetic field studies and trigger further discussions on inter-related subjects.  As in other SHINE sessions, the primary contributions will be in the form of a poster: note the 9 June deadline for the abstract. If you are interested in presenting related work during the session itself (one or two slides), please inform the conveners of the subject matter.

Conveners: Nariaki Nitta, Ming Zhang, Eric Christian and Georgia de Nolfo
