WHOLE SUN MONTH WORKSHOP

Feb 10 - Feb 11, 1997

Agenda

The goals of this workshop are to:

A) Present and determine how to coordinate data.

B) Ask (discuss) questions that need to be answered in order to achieve Whole Sun Month goals using the data.

C) Form a specific plan of attack to answer these questions.

Goal B: Questions we wish to answer

Building 26, Rm G10

4:00 - 6:00

(each main question will have approximately one hour's round table discussion. Participants will be encouraged to bring one or two viewgraphs pertaining to the question if they wish. However, the discussions will be informal, and guided by the designated discussion leader for each question.)

1. 3-d density structure of corona (Guhathakurta)

How well can we determine the 3-dimensional structure of the corona during WSM?
- how do we model density throughout the corona?
- what are strength and weaknesses of different density diagnostic techniques?
- how do we maximize the three-dimensional information from the WSM data?
- how do limb coronal structures appear projected on the disk?
- how does the equatorial coronal hole appear on the limb?

2. Temperature (Strachan)

How does temperature vary throughout the corona during WSM?
- how do we model the large-scale temperature?
- how does it vary with height?
- how does it vary between open/closed structures?
- how does it vary between electrons/ions?
- what are the strengths and weaknesses of various techniques for determining temperature?

Building 26, Rm G10

8:45 - 10:45

3. Magnetic field (Hoeksema)

How do we calculate the large-scale magnetic field in the corona?
- what role do currents (bulk/sheet) play?
- what is the structure of the heliospheric current sheet?
- how can we use in situ magnetic field observations?
- how can we use the photospheric/chromospheric field as a lower boundary condition?

4. Connections: Upper --> lower corona (Hoeksema)

How well can we connect the large-scale corona to lower coronal observations?
- can streamers be traced down to the lower corona?
- do coronal hole boundaries match modeled open field regions?
- do polar plumes trace modeled magnetic field divergence?
- how is the small-scale photospheric field connected to the large-scale coronal field?
- does the the active region during WSM have a noticable effect on the large-scale corona?

10:45 - 11:00 Coffee break

11:00 - 1:00

5. Connections: corona --> in situ (Lazarus)

How do we link the corona dynamically to in situ observations?
- how can we use answers to Questions 1-4 in solar wind models?
- how can we model the 3-dimensional wind?
- what is the radial dependence of the solar wind velocity near the sun?
- how will we compare wind models to in situ observations?
How well can we trace large-scale coronal structures out to situ observations?
- where and to what extent do we see the effect of the equatorial coronal hole?
- how can we connect in situ electron observations to our modeled coronal temperature and density?
- to what extent can we connect WSM wind composition to an origin in the corona?

1:00 - 2:00 lunch

Goal C: Plan of Attack

2:00 - 4:00 Round Table Discussion: Data usage (leader - Bagenal)

coordination of datasets (space and time)
modellers feedback: what sub-sets of data to focus on

4:00 - 4:15 Coffee break

4:15 - 6:15 Summary Discussion (Gibson)

Future plans: Who will do what by when and how?

who will present what at the Spring AGU?
what will be accomplished by next September?
