3.  General Notes Concerning MEDOC Campaign (Bernard Cougrand and Jean-Claude Vial) 
-------------------------------------------------------------------------------------

    Scientific general status:
    --------------------------	 
    SUMER, CDS, EIT will be involved in the science planning of the first week
    (21) of MEDOC campaign.
	
    GBO coordination: for the week 21, we will have the participation of THEMIS
    and other GBOs. Target coordinates will be provided by MEDOC to the observatories.
    Targets:  Filaments and prominences for JOP9 
    Others: Bright points, network, coronal holes ..
	
    Technical status: 
    -----------------	
    - Planning tools have been tested on MEDOC IWSs and on MEDOC Scientist Station
      EOF and IWS link capability: 
    - MEDOC real time telemetry (RTTM) reception and commanding are operational
    - SUMER: only RRD will be available and requested every 30 mn.
    - EIT: A disk problem was fixed today  thus the RTTM will be file formatted
           locally and EIT images immediately available at MEDOC.
    - CDS: data acquisition will be done by file transfers using the dedicated line.
    - LASCO: web data access only.
    - UVCS: web data access only.

NOTES:
------
On Wednesday, May 21, CDS running Network Study (12:19 - 17:35 UT).  
EIT points out that there will be a EIT synoptic set during that time
(13:00 -13:23 UT).

EIT observing polar plumes and microjets from 21 - 22:30 UT at the South
Pole.  Taking 195 Angstrom images with 1 minute cadence.

LASCO will be doing jet studies in C3 towards the end of next week.

The following information was received from Steve Suess concerning the
Ulysses-Sun-Earth at 90 Degrees, Joint CME Observations.  (Received
after the planning meeting but is included for distribution..):

	On day 146 of 1997 (26 May 1997) the angle between
	the positions of Earth (SOHO) and Ulysses will be 89.8 degrees
	(I'm not sure at what time during the day). The precise angle
	will be determined later from the orbital data I receive on the
	Ulysses data files.

	On day 146, Ulysses will appear to be off the EAST limb of
	the Sun.

	On day 146, Ulysses will be 10.5 degrees north of the
	heliographic equator, at a distance of 5.08 AU.

	On day 146, Earth will be 1.4 degrees south of the
	heliographic equator, at a distance of 1.01 AU.

	With luck, this is accurate information.
	See you next week,     - Steve Suess


5.  MEDOC Campaign (Detailed programs)
-------------------------------------- 
Notes by Bernard. Cougrand and Jean-Claude Vial


	5.1. Scientific contents

JOP9:

	The scientific objectives concern the diagnostic of prominences/
	filaments.
	Prime targets are quiescent prominences of the polar crown.
	The programs on SOHO have been updated and they take into account the
	important contribution of Ground-Based Observatories. They are more
	focused on density and temperature diagnostic; velocity fields at 
	different temperatures; oscillations.

	Observing times:
	7-12 UT, knowing that THEMIS core observing time will be AROUND 
	8-10UT.

	Target selection: it will be defined on the day before.
	
Bright points: 
	Diagnostic (Temperature, densities, etc) of the bright 
	points using different lines formed a different altitudes, and ratios 
	of lines sensitive to the temperature and density. 
	
Test filament/VLA:
	Simultaneous observations of a filament in UV with SOHO and in
	microwave range with the VLA, and diagnostics
	
	
	
5.2- Operating modes

5.2.1.CDS: 
	JOP9:
	EJECT_V3 (6 lines, exposure time of 16 s); POBS1_2 (13 lines but
	higher exposure time); MOVIE mode.
	Modes 1 and 3 should coincide with measurements made with the Italian 
	filter on THEMIS.
	
	Bright points: BPIAS
	
	VLA: LARGE_BP, PY24W
	
	

5.2.2 SUMER:
	JOP9:
	The MEDOC campaign begins on May 20th at 00.00UT, thus it is planned to
	switch the SUMER master base on Monday morning at 6.00 UT.
	With the experience gathered in November and January,  new or improved
	modes are tested: Lyman continuum and high Lyman lines; Lbeta and O VI
	lines; and -if possible- Lalpha out-of-limb measurements in conjonction

	with CaH (Hepsilon) on the GCT (see below).
	The daily SUMER observations will start with an He I 584 sequence which
	will enable us to superimpose the SUMER slit upon the CDS image in the 
	same line.
	
	BP: HI_TIME_RES

5.2.3.EIT: 
	Frequent He II 304 images in subfields of about 8*8
	arcmin.

5.2.4.UVCS: 
	weeks 21 and 22 will be mainly devoted to other targets but for week
	23 (and 24?) a participation of UVCS is now under discussion with 
	J. Kohl, E. Antonucci, S. Fineschi, G. Peres for UVCS. The idea is to
	obtain Lalpha ( and beta, etc..) spectra in a prominence and/or the 
	coronal cavity above.

5.2.5.MDI: 
	provides a magnetogram every 96 minutes.

	
5.3. GBO Coordinated observations
	
	
5.3.1.JOP 9:
	THEMIS: 
	IPM filter switching between Halpha and D3: we propose
	8-9 UT: D3 and 9-10 UT: Halpha (see below)

	GCT: 
	E. Wiehr : Two modes: Ca II (8542)/Hbeta and Ca II H

	Pic-du-Midi coronagraph: Halpha

	Wroclaw coronagraphs: Halpha

	Ondrejov spectrograph: multi-lines (Balmer series)

	Sibizmir is also involved
	
5.3.2.Test filament/VLA:
	VLA: (2cm - 21cm) contacts on May 19, 20 and 21
