*** MEDOC CAMPAIGN # 15 -- Week 20 ****
Weekly meeting, 13 May at MEDOC

Welcome to Z. Mouradian (JOP 177 coordinator).


Basic JOP activity :

JOP 124 : (filament oscillations) requires observations of the same 
filament from disk to limb. Optimal duration : 15 hours. (EIT 304 
sequential images would be very useful).

JOP 177 : focused on : 	
1/ spicules located as close as possible to the  Equator. 
   Lbeta, O VI with SUMER. 
2/ prominences Lbeta, OVI and Lc with SUMER. A sequence as long as 10 hours.

JOP 180 : (Magnetic Fields and Flows to Corona/Transition Region) no 
POC present at MEDOC. Joint observations with VTT between 8-12 UT.
Requires detector A/SUMER. Pointing coordinates provided by Luca Teriaca.

JOP 158 : (The fast solar wind from 1.05 to 4 solar radii ) no POC 
present at MEDOC. Will start on May 20 with detector B/SUMER.

Observations of filaments : no POC present at MEDOC. Uses detector B/SUMER 
during Week 2 but observations with A are scheduled on Week 1.

Polar coronal hole : Laurent Dolla. Program to be run before and after JOP 158.


Status of instruments :

Karine Bocchialini and Philippe Lemaire reported on detectors issues.
It has been agreed with SUMER PI that detector A will run until Friday 20
and from Wednesday 25 until the end of the Campaign. In-between, detector B
Will run within the usual constraints (out-of-limb position).


Status of the Sun :
-------------------

Various targets for filaments/prominences.
Coronal Holes well visible at both Poles.


Planning :

SUMER :
JOP 124, 177 and 180 on 17, 18 and 19 May
JOP 158 starts at 18.00 UT on May 20

CDS :
SYNOPTIC (everyday, from  0:00 to 6:00 UT) 
JOP 124 (Filament/prominence, G. Pouget, 15h) ; coordination with SUMER 
JOP 158 (Polar Coronal Hole, A. Gabriel) from Friday 20 to Sunday 22, 
        18:00-24:00 UT max, coordination with SUMER and UVCS) 
Filament observations (B. Schmieder/P. Heinzel), coordination with 
        SUMER, a few hours 
A few monitoring activities

Mon 16 May :

SUMER :
Around 12. 00 UT submode change and SUMER ON
16.00 - 24.00 UT Filament/Prominence (Lyman lines)

CDS :
00:00 - 06:30  Daily synoptic study
15.00 - 20.00  Filament/Prominence (Lyman lines)
20.00 - 24.00  GIS Meridian Study


Next meeting : Monday 16 May at 11.00
