Long discussion (again!) on the role of SOLs. It was agreed that the experience with previous SOLs (Tarbell, Polettto) was positive, and that the concept is good. John Kohl suggested to have one of the JOP-leaders for that week as SOL.
The dates foreseen by FOT:
MDI continuous Oct 17 to 21.
Planners will be: week 41: Terry Kucera week 42: Jung Chulchae week 43: Tom Ayres Oct. 13 -> Roberto Falciani: Sac Peak study of AR's Oct. 21 -> Tenerife/SUMER, EOF: Philip Lemaine
Sept. 30 - Oct. 6 Martin Huber Polar Plumes Oct. 7 - Oct. 13 John Kohl Spectrometric Intercal with SUMER Dynamics of equatorial regions with LASCO. Oct. 14 - Oct. 20 Larry Garder Calibration Oct. 21 - Oct. 27 Larry Garder Calibration Oct. 28 - Nov. 3 John Kohl Dynamics of equatorial regions with LASCO Nov. 4 - Nov. 10 Silvano Fineschi Doppler dimming and IPS Nov. 11 - Nov. 17 Giannina Poletto Serts on 11/13-14 Nov. 18 - Nov. 23 Angela Ciaravella JOP009 Nov. 24 - Nov. 27 John Raymond delta sco, beta sco, pi sco, nu sco Nov. 28 - Dec. 1 Ester Antonucci Recommend JOP2 Dec. 2 - Dec. 9 Silvio Giordano Recommend JOP2 Dec. 10 - Dec. 17 Ruth Esser Sami Solanki (JOP55)? Dec. 18 - Dec. 22 John Raymond
John Kohl would like to do JOP55 during a different week (Dec. 10-17)
SUMER also suggested doing omega1 Sco on November 24 also.
UVCS would like to do CME observations between Oct 28 - Nov 3.
Synoptic program with LASCO was foreseen to take up 50-80% of their time. The remainder would be left for special observations. LASCO depends heavily on data compression (there are 4 unique algorithms). RICE compression works exceedingly well and is the compression format of choice. Adaptive Discrete Cosine Transform (ADCT) is a less useful algorithm than initially planned (due to large numbers of cosmic ray hits).
LASCO is seeing more dynamic range in images then was previously anticipated. ADCT compression causes subtle effects to be lost. Synoptic program with RICE compression fills all observing time. When people want to do special observations and are seeing IAPs w/same thing every day - that's the way it is. LASCO synoptic program is the backbone of white light coronal observations; also includes polarization brightness measurements. Will have daily polarization and color sequences. The good news is that the synoptic program is sufficient to support most collaborations requirements.
EIT has been operating with a few constraints: No multi-spectral observations done during non-contact time due to trouble had few weeks ago with the stuck sector wheel.
Jim Lemen will perform active region, and DEM temperatures densities studies.
Oct. 1-6: JOP20 - taking a lot of time during that week.
EIT also suggest re-running JOP020 with a slower cadence: another run with 7-minute cadence over a longer period of time. EIT may also want to run more Coronal Loop Footpoint studies especially if in October the region is in MDI's Hi-Res field-of-view.
EIT argues strongly for more TLM bandwidth.
EIT prefers to get full-field rather than subfield image since the latter may cause damage to their detector in the pixels not read out.
During the continuous time in October from 8-15 UT, Ted Tarbell will be trying to get La Palma support. In other weeks, there will be 3-day blocks for helioseismology and MDI is open to suggestions for the other times during the week. Other priorities include Polar Plumes and Coronal Hole observations. Also JOP052.
MDI showed viewgraph of long-term pointing stability and are still not sure what caused mid-August pointing correction (CELIAS CTOF anomaly took place on 18/19 August).
Nominal. All staying in the same mode
Doug Biesecker and Sarah Gibson will give a brief presentation at the November SWT. On Feb. 10-11, they will organize a small workshop at GSFC to discuss JOP044 results. The first day they will present observations/models and on the second day they will discuss observations. At AGU meeting in May, they intend to have a special session for JOP044 results. All agree, we need to look at data more before making decision to run JOP44 again.
There are many new joint observing programs: JOPs 51-55. See Web pages for details.
Lyndsay Fletcher proposes to run JOP033 starting Oct 13 and again on Nov 8. JOP033 will run 3-4 hours per day, 3 days when appearing on the limb (both East and West), and once on the disk. CDS, SUMER, Yohkoh BCS, will participate; for limb targets add EIT and UVCS. SUMER and CDS programs have been tested for this.
----- Included Message ----- PROPOSAL FOR REGULAR SOHO-YOHKOH SMALL WORKSHOPS ________________________________________________ Hugh Hudson (Yohkoh/SXT) Piet Martens (SOHO Science Operations Coordinator) We have been brainstorming on the idea of SOHO-Yohkoh workshops. We came up with the idea for a format very similar to the very succesful CDAW workshops that the Hawaii and SXT people have held The following is a synopsis of our ideas. FORMAT: Small (< 20 people) weeklong workshops on very narrowly focussed subjects, with about half discussions, and half working sessions around workstations. REQUIREMENTS: Sufficient and powerful workstations, easy access to SOHO and Yohkoh data archives. Sufficient workspaces. Commitment and detailed preparation by participants. CADENCE: Twice a year. Need good planning concept, say, March '97 equinox, and every equinox thereafter. LOCATION: GSFC and ISAS (reduces travel needs; requirements met). I volunteered to organize the first one at GSFC, so that the Yohkoh people can familiarize themselves with the way SOHO operates. Later places like Lockheed, Bozeman, Medoc, and RAL may be appropriate. PUBLICATIONS: No Proceedings, but (this would be a new wrinkle) Web summaries of the activities. Acknowledgements in papers encouraged. Preparation grunt work (like calibrations and co-alignment) can also be done jointly through Web pages. ORGANIZATION: Hugh and I will do the leg work for the initial meetings. After that I hope the thing will get a life of its own, and local organizers do most of the work. We envisage an official "organizing" or "steering" committee with (at least) one representative for each PI team involved. That group would take the decisions on meeting subjects, locations, dates, and participants, as well as the sensitive subject of data rights -- although I expect that this will be less of an issue by March '97, and fade away after that. SUBJECTS: Initially we may want to focus on topology types of subjects, to avoid calibration issues that are not yet resolved. A list of subjects mentioned: * AR Region Development (e.g. JOP018) * Emerging/Disappearing Flux and Coronal Effects (e.g. JOP001) * Eruptions and CME's * Bright Points * Plumes (several campaigns and JOPs) * Jets * Filaments and Prominences (several JOPs) * Coronal Loop Structure Defined by Yohkoh and by SOHO * Yohkoh-SOHO Intercalibrations and Temperature Determinations ----- End Included Message ----- ------------------------------------------------------------------------
