Material for Session 1 at SHINE 2019

Brief introduction - At this year's SHINE meeting, Session 1: Exploring the Middle Corona, we will be exploring the middle corona. This page includes links to movies for the three events that will be discussed at this years (2019) SHINE meeeting, session 1. The Session abstract follows:

The middle corona — the region of the corona extending out to heights of about 5 solar radii — has not been well explored. However, this region has long been understood to be the important region where CMEs and the solar wind are accelerated, and the heliosphere shaped; where the plasma beta changes from a magnetically dominated regime to one dominated by thermal-pressure.

Historically, the dearth of observations can be attributed to the difficulties in observing the middle corona; EUV imagers did not have observing plans designed to reveal the emission from this region, and coronagraphs have inherent difficulties with observing down to the inner corona.

In recent years there has been a push to explore this region through large field-of-view imagers combined with radio observations and models. However, we're still waiting for the next generation of imagers to fully explore the energetics and dynamics of this region.

In this session we want to explore the region with available instruments, combining available data-sets, e.g. large field-of-view EUV images, radio observations, coronagraphs etc. with models, to help characterize how structures change throughout the region.

We have identified three dates; two (2017-Apr-1 and 2017-Apr-18) which yielded near-limb eruptions so that we can explore the energetics and changes in the eruptions as they evolve through the region, and the third date (2017-May-10) which exhibited low activity near the limb to help explore the background corona/heliosphere interface.

We welcome contributions that model the eruptions on April 1 and 18 2017 and observations that will help characterize the event and provide constraints to the models. In particular exploring the energetics in the wake of the CME and how they evolve across the magnetic/thermal regime change. We also welcome more general contributions on observations, models, and analysis of the middle corona that might point to additional research directions.

In summary, to understand how the community may better coordinate future missions and observations, the session will address the following questions:

We will perform two eruptive case studies (2017-Apr-1 and 2017-Apr-18), to see how the eruptions evolve through the region.
For the above case studies, we will look at the changing energetics observed in the region throughout and following the eruption.
The 'background' middle corona will be studied during a period of low activity (2017-May-10) will be studied to help characterize its basic structure and energetics.
Comparisons drawn between the above mentioned periods.
General contributions that address observation or modeling of this important but often overlooked region.

To help people visulaise the data, a series of movies have been made using the jhelioviewer tool. These movies are included below. The movies are separated into full-disk movies and Zoomed movies. Below are links to AIA, LASCO and SWAP. SUVI fits files from 2017-Apr-01 and 2017-Apr-18 are also included.

At this years SHINE meeting we will also be hosting a special session poster, called "Exploring the Middle Corona - Deface this Poster"

The poster number can be found here, and the abstract is as follows: This poster outlines Session 1 of the SHINE meeting: Exploring the Middle Corona, where we will probe that illusive region of the corona roughly located between 1.5–4 Solar radii, combining observations and models of the region. Some key questions the session aims to address are: 1) How do eruptions evolve through the region? 2) What are the changing 'energetics' observed in the region throughout and following the eruption? 3) What can be learned about the ‘background’ middle corona? In the spirit of the SHINE meeting format, we've designed this poster to be defaced! (in a good way) The poster briefly outlines the session, but has sections left intentionally blank for YOUR input. As the meeting progresses we will update the poster with output from the workshop, and hopefully come up with an ongoing discussion. So please come along and be part of the session!

If you're at SHINE this year come and be part of the session on Tuesday August 6 14:00 - 15:15 and then again 15:45 - 17:00 and follow the poster through the week as its updated. More details acan be found here.
