SOHO SPWG Minutes
SPWG Meeting Minutes June 11, 1999
1. Review of action items
- None Open
2. Boundary conditions
- Upcoming Maneuvers
No Maneuvers in July. No update on September activities.
- MDI Continuous
The next MDI continuous is July 15 at 04:10 UT to July 20 at 07:20 UT
We ask that MDI submit OCD for this activity by July 1, noon local time.
3. Priorities for the coming month
a) Joint observing plans
SERTS -- Bill Thompson announced a new updated WWW site:
For other plans see the monthly calendar.
b) Individual instrument plans
CDS -- Limb active region loops, sunspots, trapped waves (if a good
coronal hole at the pole), quiet sun at disk center, Birmingham
Flare Study in conjunction with TRACE two-week AR tracking.
SUMER -- They would like to perform detector engineering prior to August
stellar observations. However, the date of this activity is
still to-be-determined. Perhaps late July or early August.
When this engineering is done -- they would like to run ICAL001
twice.. once on each detector. During the detector engineering
and the August stellar observations -- do NOT plan on having
SUMER available for collaborations. SUMER also noted they
have a sungrazing comet observing program in place.
UVCS -- the last 2 weeks of July are still open. For the first
two weeks Ester Antonucci will concentrate efforts on one
quadrant of the Sun with long exposures. Macro Romoli will
then perform work in the white light channel detector.
LASCO -- C2 and C3 synoptics continue.
EIT -- Will enjoy submode #6. 195 Angstrom CME watch continues. No bakeouts
planned anytime soon.
MDI -- Mentioned the "MDI Synoptic Magnetic Field Data" web site:
(Note: After the meeting a link was added going from the
SOHO synoptic data page to the MDI synoptic data site).
More flexible to collaborate. Concentrating on LaPalma and TRACE
sunspot observations. During the July continuous contact
they will focus on a specific active region target.
TRACE -- was not present but supplied the SOC with updates via
their calendar and e-mail:
Julia Saba remarked that TRACE gets better data sets
when the study/target duration is longer than 2 hours.
Some people in SOHO may not be aware of this fact.
c) Intercalibration activities
Intercalibration 001 penciled-in for Wednesday, July 7.
Could perhaps the author of the original ICAL001, Richard Harrison,
get in touch with TRACE to see if their observing program
has become standard enough to incorporate/update the ICAL001
4. Preview of future months
* See the Monthly Calendar at:
5. JOPs status
- Review of JOPs as number approaches/reaches 100.
Status: Postponed until after September 1999.
- JOP098 was updated.
6. New JOPs
- Next SPWG: Friday, July 23.
Deadline for eclipse requests or JOPs in by Sunday, July 18.
On July 19, SOC will place inputs on WWW (with appropriate "TBC at
SPWG" banners). At the SPWG on 23 July, sort out conflicts and update
- SWT on June 21 (Draft Agenda is below)
- There was discussion of the Max Millennium Program. Laura Roberts
has received some e-mail from Richard Canfield who is the
HESSI Co-Investigator responsible for ground-based observations
and is developing the Max Millennium program infrastructure.
This e-mail was discussed and is appended to these minutes.
SOHO is excellent at observing pre- and post- flare activity
and global properties.. but it is questioned how much time
for example, CDS, would like to spend observing flares.
Probably the best time to open a dialogue with the Max Millennium
folks would be the October 21-22, 1999 SWT meeting at GSFC.
Joe Gurman will mention at the SWT and if the PI's agree with the idea.
He'll invite Drs. Canfield and Dennis to the October SWT on

>HESSI is due to launch in July 2000. Between now and then I expect a small
>number of scheduled Max Millennium campaigns. As well, I expect plans to be
>defined for certain flare-related targets of opportunity, which will not be
>scheduled in advance, but rather will be announced at the last
>minute, when the
>targets present themselves. I, for example, will work with Sara Gibson on a
>target-of-opportunity campaign to be run when a sigmoidal region presents
>itself. I realize that such last-minute activities will not fit comfortably
>into the SOHO planning process, but they are critical to the success of any
>flare-related satellite like HESSI. Finally, as we get closer to launch, we
>will begin to designate a daily Max Millennium target and a default observing
>plan, to be used at observatories active in flare research if nothing else is
>scheduled. Of course, we will try to work with other campaigns and spacecraft
>-- e.g. the coming whole sun month -- and will do our best within
>of our very flare-related goals.
>IN summary, before the launch of HESSI, the Max Millennium program will mature
>to a level of activity such that on every day of the year there will be, under
>the imprimatur of Max Millennium, one of the following: (1) a
>such as the one Dale and Neale are planning; (2) a specific target of
>opportunity plan such as the sigmoid one Sarah and I are planning;
>(3) a default
>plan and associated flare-productive active region.
>For an overview of other aspects of where Max Millennium is headed,
>see the Max
>Millennium home page link "Chicago AAS/SPD", then "Max Millennium Program in
>Would you like to organize a Max Millennium Coordinated Observing Plan
>and lead the campaign it describes, using the Max Millennium
>infrastructure, either on a scheduled basis or target-of-opportunity
>basis? At this time I am aware of only one of each of these two types
>under development -- (1) the soon-to-be-scheduled "3-D Structure of
>Flaring Active Regions" (Gary and Ranns), described in Dale Gary's
>previous messages (in the Max Millennmium science hypermail archive),
>and (2) "Eruptive Flares Associated with Sigmoids" (Canfield and
>Gibson), a target of opportunity campaign that is in a preliminary
>stage. I invite all scientists interested in solar flares to contact
>me about a Coordinated Observing Plan that suits their scientific
>interests, unique capabilities, and the goals of the Max Millennium
>program. For example, do you have the observational facilities and
>solar observing experience to identify a region that promises to become
>one of those historic flare-productive regions that produce multiple X-
>and white-light flares? Such regions will produce the most spectacular
>discoveries when HESSI comes on line in mid-2000, and we want to be
>ready -- I would like to hear from you!
>The Max Millennium Coordinated Observing Plan presently being organized
>by Dale Gary and Neale Ranns is a great example to follow. The
>template for such Coordinated Observing Plans is available on the
>"Coordinated Observations" link on the Max Millennium home page,
>http://solar.physics.montana.edu/max_millennium. Note the other
>developments under construction at that web site -- e.g., the Sun Today
>page, intended to make it easy for anyone to run a Coordinated
>Observing Campaign. If I have not included a link that you know to be
>useful for evaluating current solar conditions, please contact me at
>the e-mail address below, and I will add it to that page.
>Two talks from the recent American Astronomical Society meeting in
>Chicago, discussing 1999/2000 plans for the Max Millennium program and
>the HESSI Flare/Synoptic dabase, are available on the web site
