SOHO SPWG Minutes



SPWG November 19, 1999 Meeting Minutes

1. Review of action items

* Action on: N. Gopalswamy Closed Submit new JOP to SOCs: Microwave Enhancement in Coronal Holes

2. JOPs status

- UPDATED: * Intercalibration 1 * JOP017: Dynamics of Arch Filament Systems * JOP107: Lyman lines series in prominences and Lyman continua [JOP017/107 versions ran during last MEDOC Campaign] Changes reflecting current modes of observation were acknowledged. Auxiliary information currently attached to JOP017/107 will be moved to the Campaign database and/or auxiliary files under the JOPs web page. - NEW: * JOP114: Pre-Eruptive Filament Structures - OK for now, possible MDI participation to be specified * JOP115: Search for UV Signatures Corresponding to Microwave Enhancement in Coronal Holes - OK for now, MDI portion to be clarified * JOP116: Filament Doppler Shifts at Multiple Temperatures - OK.

3. Boundary conditions

- Upcoming Maneuvers * February 23, 2000 -- Momentum management scheduled on or before. Momentum Managements will most likely occur with 3-4 months interval in the future, though the scheduling is more flexible now that no DSN hot backup is required. - MDI Continuous * December 8-13, 1999 -- MDI 5-day Continuous

4. Priorities for the coming month

a) Joint observing plans * November 29 - December 12, 1999 JOP112: Coordinated SOHO-Ulysses Elemental Abundance Study UVCS/CDS/SUMER/LASCO/Ulysses JOP102: Structure of Coronal Holes with Plumes CDS/MDI/SUMER/EIT/Ulysses SUMER,CDS will plan from MEDOC for their participation Contact: G. Poletto (EOF) * December 9, 1999: FLARE GENESIS experiment, borne by a balloon around Antartica for 2-3 weeks, Max Millenium Project. Contact: Brigitte Schmieder See http://sd-www.jhuapl.edu/FlareGenesis As of Monday November 22, this is SOHO JOP117. b) Individual instrument plans MDI - Flare Watch/Time-Distance CDS - AR studies/Sunspot studies/Loops on limb December 25 - January 2: X-mas studies (possibly in MDI HiRes) EIT - CME Watch starting December 10 SUMER - SOHO-Ulysses Quadrature/MEDOC. UVCS - JOP112 (2weeks) Instrument characteristics (1week) CME Watch (1week) Global survey of the extended solar corona (1 week) LASCO - December 20-25, 1999 -- Milky Way Observations. Synoptics. TRACE: Continuous 4-panel mosaic East limb study (22 Nov - 6 Dec) c) Intercalibration activities * December 15, Intercal 001, CDS/EIT

5. Preview of future months

* MDI Continuous - January 13, 1410 UT - January 18, 0850 UT - February 10, 1140 UT - February 15, 0750 UT - May, 3-month continuous (TBC) * Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) - Launch scheduled February 15, 2000. Continuous coverage for 39 days from launch. * For latest updates, see the Monthly Calendar at: http://sohowww.nascom.nasa.gov/soc/head_calendar.html

6. AOB

* Discussion based on input from SWT 29 on the content of the daily, weekly & SPWG meetings. Some points were: - The extent to which SPWGs should be driven by fixed input from individual instruments versus meeting discussions. - The SPWG does fulfill its purpose in coordinating joint observations and sharing information on individual instrument plans. - It would be nice if JOP [co-]authors could be present at SPWG meetings to give a brief introduction of the JOP. - Once again, we encourage people to volunteer as Science Operation Leaders. None of the meeting participants volunteered; we decided to invite someone in partcular. Invitation is sent. * Next SPWG: Monday, December 20. Time TBD. * REMINDER: DSN support should be requested at least 6 months in advance. Keep this in mind for: ground-based collaborations that require MDI support, stellar observations that require NRT, etc. * REMINDER: Submissions to calendar/jops@esa.nascom.nasa.gov are most welcome to enable coordination with other instruments, spacecraft or ground based observatories.
