SOHO SPWG Minutes
SPWG FINAL MINUTES
Friday 24 June 2005
1. Boundary conditions
- SOHO is upside down until the next keyhole, Aug 30-Sep 29.
- Scheduling windows for keyhole periods through 2005 are listed on
the SOHO calendar. For estimated keyhole dates through 2008 see
http://soho.nascom.nasa.gov/soc/keyholes.txt
- Except for Major Flare Watches, TRACE will be doing full disk
mosaics if/when EIT is not able to do synoptic sets due to keyhole
operations.
- MDI continuous contacts are listed in Section 2 a) below and on the
SOHO calendar.
MDI can only support requested observations with full disk, 1 minute
cadence Magnetograms and Dopplergrams from June 25 through Sept 30,
2005. Due to the 60 day Continuous Contact (June 25-August 28), MDI
will be unable to provide any high resolution observations during
that time. Due to the June 2005 and September 2005 Keyholes, MDI
will be unable to provide most high RATE observations for any
requested observations and the default program during the Keyholes
will be either full disk, 1 minute cadence Magnetograms/Dopplergrams
or full disk, 1 minute cadence Magnetograms/Continuum Images. Send
email to mdi-ops@mdisas.nascom.nasa.gov to request observations.
Each request will be evaluated on an individual basis by the MDI/SOI
team.

2. Priorities for the coming month & more
a) Joint observing plans and campaigns
Continuing campaigns:
* 2002/02/25-- JOP136 Default RHESSI Collaborations (#6850), POC:Stein Haugan
* 2002/04/25-- JOP159 CMEs in Lyman-alpha (#6870), SWAN/LASCO/EIT/UVCS,
POC: Chris St Cyr, Eric Quemerais
* 2003/05/13-- Default CDS Co-observations with TRACE (#6950)
* 2003/07/01-- Network-Internetwork Oscillations (#7033), EIT/TRACE,
POC: Scott McIntosh
* 2004/02/19-- JOP175 Extended Filaments at the Limb (#7135),
EIT/TRACE/LASCO/UVCS,
POC: Chris St Cyr (Chris.StCyr@nasa.gov)
* 2005/01/24-- JOP153/MMOP003 Future Major Flare Watch (#8002)
Campaign #6850 is for "individual instrument studies" selecting an AR
target [partially] influenced by the Max Millennium target selection
to maximise chances of serendipitous co-observations.
EIT supports all with half/full-res 195 Å CME watch in submode 5/6,
except JOP175 getting half/full-res 304 Å CME watch in submode 5/6,
and Network-Internetwork Oscillations which is TBD by Scott McIntosh.
As long as the S/C is in submode 6, all EIT CME watch will be in full
res.
* Jun 5-25 26m Keyhole (Jun 9-20 34m Keyhole)
* Jun 23-Jul 6 Moat Flows and Magnetic Features, MDI/TRACE/Sac Peak,
POC: Mandy Hagenaar (hagenaar@lmsal.com)
Due to the 60-day continuous contact, MDI can only support with one-minute
cadence, full disk Dopplergrams and magnetograms, with continuum images
every 96 minutes.
* Jun 23-Jul 7 Active Region Tracking, SST/DOT/TRACE/MDI,
POC: Tom Berger (berger@lmsal.com)
May be ending on July 2.
* Jun 25-Aug 28 MDI 60 Day Continuous Contact
The plan is Full Disk Magnetograms and Dopplergrams.
* Jul 3-14 JOP181 Fine Magnetic Structures/Coronal Heating (#7138),
SST/VTT/DOT/CDS/EIT/MDI/TRACE,
POC: Yukio.Katsukawa@nao.ac.jp,
Local POC: Ted Tarbell (tarbell@sag.lmsal.com) & Dawn Myers
Due to the 60-day continuous contact, MDI can only support with one-minute
cadence, full disk Dopplergrams and magnetograms, with continuum images
every 96 minutes.
* Jul 4 Comet 9P/Tempel, SWAN/Deep Impact,
POC: Eric.Quemerais@aerov.jussieu.fr
* Jul 07 Sounding Rocket Launch, VAULT/SUMER/CDS/EIT/TRACE/MDI,
16:20 UT, POC: Enrico Landi (landi@medusa1.nrl.navy.mil) and
Angelos Vourlidas (vourlidas@nrl.navy.mil)
Backup launch days are on July 11 and July 14. There will be submode
changes to submode 5 the day before and to submode 6 the day after the
launch.
We have an extra downlink station for the July 7 launch date, not for
the backup days. MDI full disk magnetograms are used for support, so
we will not be in record while in contact.
CDS will support. Studies TBD.
* Jul 20-26 Faraday Rotation Measurements, UVCS/Cassini/LASCO(TBC),
POC: Mari Paz Miralles (mmiralles@cfa.harvard.edu)
Joint observation during the 2005 Cassini solar conjunction (north
coronal hole pass). Mari Paz will contact LASCO for collaboration.
* Jul 23-29 JOP083 Heating of Coronal Loops, CDS/TRACE/MDI,
POC: Jane Noglik (jbnoglik@uclan.ac.uk)
Building on the JOP83 observations from August 2004, TRACE and CDS to do
similar observations, MDI for on disc targets only
Full Disk Magnetograms/Dopplergrams ONLY from MDI.
* Aug 2 CELIAS SEM Calibration Rocket Flight,
CELIAS/EIT/CDS, 18 UT,
POC: Andrew Jones (arjones@usc.edu)
We can not get a backup station for this. MDI accepts to be in
record for about 10 minutes, but strongly suggests not to lengthen
this period considering the impacts to the 60 day continuous contact.
* Aug 13-24 JOP157 Bright points in ARs, CDS/EIT/MDI/TRACE(TBC)/THEMIS/VTT,
POC: Etienne.Pariat@obspm.fr, TBC
EIT will support with 195 CME Watch.
Due to the 60-day continuous contact, MDI can only support with one-minute
cadence, full disk Dopplergrams and magnetograms, with continuum images
every 96 minutes.
CDS support has been confirmed.
* Aug 18 EIT Shutterless #20, Segment 1, 17:00-19:40 UT
* Aug 18 Sounding Rocket Launch, MOSES/CDS/EIT/MDI/TRACE, ~17:45 UT,
POC: Charles Kankelborg (mithra.physics.montana.edu), TBC
We were unable to get a backup station for this new date. Since MDI
has been requested to supply full disk magnetograms, the spacecraft
will not be recording while we are in (continuous) contact.
CDS studies are under consideration.
The EIT Shutterless is supporting the MOSES launch.
* Aug 18-21 Spicule Study, TRACE/SST, POC: Jay.M.Pasachoff@williams.edu
* Aug 24 EIT Shutterless #20, Segment 2
The shutterless run for August 31 has been moved to August 18.
As always, supporting with at least Full Disk Magnetograms/Doppler.
* Aug 30-Sep 29 26m Keyhole (Sep 6-22 34m Keyhole)
* Sep 1-10 Wave Propagation from Photosphere to Corona, MDI/SST/DOT/TRACE,
POC: Bart DePontieu (bdp@blackadder.lmsal.com)
MDI will try to collaborate as much as DSN allows (half of the period is
within the 34m keyhole) and as long as this study doesn't conflict with
JOP178 (they might actually have overlapping observations at certain times).
Request for HR Mag/Doppler/Filtergrams or FD Mags/Doppler.
* Sep 7-21 JOP178 Filament and its Environment, MDI/CDS/EIT/TRACE/GBOs,
POC: Thierry Roudier (roudier@bagn.obs-mip.fr), TBC
EIT supports with 195 Å CME Watch plus TBD 304 Å observations if not
in bakeout or otherwise prevented by keyhole.
MDI will try to collaborate as much as DSN allows (during 34m keyhole) with
HR or FD Magnetograms.
TRACE will join on September 11 (when Bart DePontieu's study is
finished).
* Sep 22-28 Filament Observations, CDS/EIT/THEMIS,
POC: Guillaume.Pouget@ias.u-psud.fr, TBC
CDS supports as the keyhole schedule allows.
EIT participation beyond CME watch (if not in bakeout - TBD)
dependent on contact and ground observing schedules, since it could
involve sector wheel motions.
* Sep 23-Oct 17 Magnetic Elements and Waves in the Chromosphere,
MDI/TRACE/SST, POC: Mats.Carlsson@astro.uio.no
MDI: This begins during the 26-m Keyhole and overlaps with a 5-day
continuous contact period, Oct 12-16. HR Mag/Doppler program likely for the
continuous contact period if target in the high res FOV.
* Oct TBD Sounding Rocket Launch, EUNIS/EIT/CDS/TRACE,
POC: Jeffrey.W.Brosius.1@gsfc.nasa.gov, TBC
* Oct 6-17 Fine Scale Structures,
SUMER/MDI(TBC)/CDS(TBC)/THEMIS/DOT/TRACE,
POC: Georgia Tsiropoula (georgia@space.noa.gr)
JOP description being worked on.
CDS does not seem to have received a request yet.
MDI: This occurs mostly during the 5-day CC period. The MDI program for that
period will likely be high resolution. We should be able to give them good
support on Oct 6-11, DSN schedule permitting, and support during the
continuous contact, if they coordinate with with the Magnetic Elements &
Waves program.
Submode changes for this will be on October 5 and 18, TBC.
* Oct 12-16 MDI Continuous Contact, TBC
MDI: High res Mag/Doppler or 3-variable high res program likely since there
has been interest expressed by several collaborators, provided the targets
are in the MDI high res FOV.
* Oct 18-22 JOP179 Energy Propagation in XBPs, CDS/EIT/MDI/Hida,
POC: Tetsuya Watanabe (WATANABE@uvlab.mtk.nao.ac.jp)
Hida observing times are about 21 - 06 UT.
CDS will support, but needs more details.
MDI: The request is for FD Magnetograms & Dopplergrams at 1-min cadence,
which we can probably provide, DSN permitting.
EIT support is 195 Å CME watch (submode 6)
* Oct 19, 26 EIT Shutterless, TBC
b) Intercalibration activities
Last Intercal 1: April 6
* Week 26 ICAL01 (#7113), CDS/EIT
* Week 30 ICAL01 (#7113), CDS/EIT
c) Individual instrument plans
MDI:
See section 2a for MDI continuous contact periods.
MDI may reduce the ALT cadence during Keyholes to be less than 15 ALT
magnetograms per day if the lack of high rate telemetry is such that
we will lose all or almost all of the 15 ALT Magnetograms each day.
The ALT cadence will be decided on an individual Keyhole basis and
even a daily basis during each Keyhole depending on the 70m antenna
availability at the time.
All requests for MDI support need to be made several months ahead of
time and sent to mdi-ops@mdisas.nascom.nasa.gov. Even outside keyholes,
MDI can only do 1-minute cadence observations when we have contact and
there is no recorder dump in progress.
MDI's REQUEST page is at
http://mdisas.nascom.nasa.gov/coordination.txt NOTE: Listing of a
study on that page means *only* that a request has been received, not
that it will necessarily be supported.
A description of MDI Observing Modes most used for JOPs and campaigns
(FD vs. HR) can be found at http://mdisas.nascom.nasa.gov/Collaborate.
Anyone requesting MDI observations is encouraged to read this page in
order to have a better idea of what observing modes would be best suited
for a particular study. More detailed information about how MDI
operates, observational constraints and telemetry information can be
found at http://mdisas.nascom.nasa.gov/MDI_Collaboration_Details.
UVCS:
For weekly plans, see the SOHO calendar and the UVCS planning page:
http://cfa-www.harvard.edu/uvcs/observations/obst.html
The following are listed because of NRT requirements or as candidates
for collaboration (with e.g. CDS):
* Jun 24-30 UVCS Observations of North Polar Coronal Hole
* Jul 1-8 UVCS Observations of the South Polar Coronal Hole
* Jul 9-19 UVCS Measurements of Suprathermal Seed Particle Populations
in the Extended Solar Corona
* Jul 27-31 UVCS Streamer Study
UVCS is also contacting CDS regarding a possible collaboration on
the CDS coronal hole observations June 27 - July 2.
CDS:
See their request diary for details:
http://solar.bnsc.rl.ac.uk/scientificops/request.shtml
CDS will consider joining UVCS studies above if time allows.
LASCO/EIT:
SUMER:
Will be observing for the VAULT launch on July 7 and then again in
October.
TRACE:
The TRACE Mission will not be terminated on 1 October. NASA has
decided to have a Senior Review of all Sun-Solar System missions this
fall, the outcome of which will determine the level of support (or no
support) for each mission in the future. TRACE operations will
therefore continue through at least the rest of the year, especially
through the summer observing season in the northern hemisphere.
NOTE that TRACE in general reserves the right to withdraw support from
agreed, existing collaborations if a sufficiently "good active region"
is called by the Max Millennium group.
3. AOB
* Next SPWG:
F Jul 29 SPWG Meeting, TBC
UVCS prefers July 22. We will try to get the draft minutes out before
then to allow a UVCS response, but no promises. Input can also be sent
prior to the draft.
The rest are FYI items:
* If anyone has projects that require high rate (i.e. 1 minute
cadence) MDI support, now is a good time to ask! If you need MDI
data, make sure you request it specifically. There is no significant
change in the shutter performance over the last 10 months;
monitoring continues, but no immediate changes in operations are
planned.
* 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.
