SOHO SPWG Minutes
Friday November 22, 2002
1. Review of action items
From last meeting:
* All teams: Give a list of email addresses to be added to the SPWG list
(to make sure all relevant people receive the draft and final minutes)
We will add: trace_planner@cheyenne
Remove: Several, by request (new duplicates and dead mailboxes)
* All teams, each SPWG meeting: Designate one person to be point of contact for
collaborations and to review & "sign off" on SPWG draft agendas
The following list is based on inputs and *assumptions*:
CDS: Andrzej Fludra
CELIAS: Peter Bochsler
CEPAC: Jarmo Torsti, Horst Kunow
GOLF: Alan Gabriel
EIT: Joe Gurman (Alex Young is backup)
LASCO: Gareth Lawrence
MDI: Rock Bush - Sarah Gregory is POC for collaborations
SUMER: Werner Curdt
SWAN: Eric Quemerais, Asko Lehto
UVCS: Yuan-Kuen Ko
VIRGO: Claus Frolich
TRACE: Dawn Myers
Replies from CELIAS, SWAN & VIRGO still pending for both of the above.
2. Boundary conditions
* The next MM/SK maneuver is tentatively scheduled for February 19, 2003.
Fuel estimate for stationkeeping: 0.4xx kg.
* No action for SOHO during the Leonids meteor shower (Nov 18 & 19)
* TRACE is in eclipse season
* Christmas Eve and Day will have limited contacts, suggestion for the
Christmas week follows:
Monday and Thursday will be normal
Tuesday (Christmas Eve): D66 06:55-11:35 UT, D27 18:30-23:30 UT
Wednesday (Christmas Day): D66 06:55-12:00 UT, D27 19:25-23:05 UT
There may be limited contacts on New Years Day as well
* MDI continuous contacts:
Dec 26-27 MDI 2-day continuous contact
Jan 20-Feb 16 MDI best effort continuous contact period 2003
Note: The 5-day continuous planned for December 26-31 has shrunk!
Submode 6 except for these submode 5 periods:
November 15, 17 UT - November 22, 17 UT (SOHO-Ulysses quadrature support)
December 2, 19 UT - December 4, 20 UT (SUMER Eclipse support)
April 7 - approximately - for one to two weeks (SUMER mini-campaign)
* Commanding outlook: See AOB section.
NOTE: Late additions:
* The ground-observable Mercury disk transit on May 7, 2003, is expected to be
visible from SOHO (details pending).
* The ground-observable Venus disk transit on June 8, 2004 will miss
by about 160 arcseconds as seen from SOHO, from the latest calculations.
3. Priorities for the coming month (W49-W52; December 2 - December 29)
a) Joint observing plans and campaigns
* Nov 25-Dec 3 SOHO-Ulysses quadrature (PA 296.7), UVCS/Ulysses,
POC: Luca Teriaca/Giannina Poletto
* Nov 26-27 Extended Observations of AR Loops, CDS/EIT, POC: Jack Ireland
* Dec 4 Total Solar Eclipse, EIT/LASCO/SUMER/UVCS/MLSO/GBO,
SUMER will command from MEDOC. Additional observing details will be
put on the web pages. The SSR will be in record from 05:15 - 09:30
UT. TRACE has not received any requests for eclipse support yet -
contact email@example.com if you would like to
* Dec 10-12 Blinker Study, CDS/MDI/TRACE/Tenerife/La Palma, 9-16 UT,
POC: Jack Ireland (local)/Hardi Peter
* Apr 2003 JOP161 Comprehensive Footpoint Study,
SUMER/CDS/EIT/MDI/TRACE, POC: Scott McIntosh
CDS, EIT, TRACE, MDI agree to a test run (time TBD - early in 2003).
MDI High Rate may be requested for the real campaign. Some details in
the JOP will be filled in, e.g: EIT & CDS observing details (EIT
program will be something other than Intercal 1 program. ) LASCO
observations may be impacted by EIT (both test and proper runs),
they agree in principle, pending discussion at next telecon.
* JOP159 CME's in Lyman-alpha (#6870), SWAN/LASCO/EIT/UVCS*,
POC: Chris St Cyr, Eric Quemerais
Targets of opportunity for the whole period:
* JOP136/MMOP009 Default RHESSI collaboration (#6850)
* JOP153/MMOP003 Major Flare Alert (#6892)
Campaign number 6850 has been set aside for "individual instrument studies"
that select their AR target [partially] influenced by the RHESSI target. Note
that the RHESSI target will be observed by a significant number of ground
based observatories, so chances for serendipitous co-observations are larger
when selecting the RHESSI target.
b) Intercalibration activities
Last Intercal 1: November 13 (Week 46)
* Dec 3-5,18 Intercal 1, CDS/EIT, POC: CDS/EIT Planners
c) Individual instrument plans
(See the SOHO monthly calendar for weekly plans)
See their request diary for details
EIT Shutterless: January 8 (primary), January 23 (backup)
EIT Bakeout tentatively scheduled for January 31 - February 3.
During TRACE eclipse season (starts Novermber 4, ends in February), TRACE will
do 3 loads per week during eclipse season and stay with one wavelength for an
extended period of time. No additional collaborations will be done other than
those previously agreed to.
* Next SPWG: Friday December 20 RIGHT AFTER WEEKLY MEETING IN THE EOF.
* Instrument teams should send 1-3 lines with their tentative weekly
plans 10 minutes before the daily/weekly meetings.
* DSN support should be requested at least 6 months in advance. Keep
this in mind for: ground-based collaborations that require MDI
support, stellar/shutterless observations that require NRT, etc.
* If anyone has projects that require high-cadence MDI support,
now is a good time to ask! If you need MDI data, make sure you request
* Commanding outlook
