  1. Solar Orbiter EUI/SOLAR ORBITER Report of the Science WG T. Appourchaux, F. Auchère, L. Harra, E. Marsch, L. Teriaca, J.-F. Hochedez, U. Schühle J.-C. Vial EUS - Science, JCV,RAL, March 2006

  2. EUI / Solar Orbiter Our Mandate (1) : Definition of scientific objectives through building observing programs detailing : targets, wavelengths, spatial and spectral resolution, cadence, exposure time, duration, data selection ·     Collecting the photometric information from the Photometry WG ·     Liaising with other instruments Science Teams (EUS, VIM, COR, in situ) to investigate the common objectives and the joint science to be made (i.e. possible). ·     EUS - Science, JCV,RAL, March 2006

  3. EUI / Solar Orbiter Our Mandate (2) : ·    Building complete observing scenarii (target, FOV, cadence, etc.) covering the whole perihelion duration in liaison with the Compression and Data Selection WG ·     Prioritizing the objectives/programs ·Translating the prioritization in terms of instruments parameters (wavelengths, etc...) ·Liaise with the Radiometry, Functionality of Electronics, Compression and Data Selection, Coatings and Mirrors WGs EUS - Science, JCV,RAL, March 2006

  4. EUI / Solar Orbiter Call for proposals (Spring 2005, from inside the consortium) 14 proposals, more or less elaborated and following two different formats 12 for HRI, 1 for HRI and FSI, 1 for FSI All HRI proposals use the close-up capability (spatial resolution) + co-rotation + polar view HRI proposals combine with EUS and/or VIM observations EUS - Science, JCV,RAL, March 2006

  5. HRI coronal proposals (1) EB: E. Buchlin, SG : S. Galtier, LT : L. Teriaca, JCV : J.-C. Vial EUS - Science, JCV,RAL, March 2006

  6. HRI coronal proposals (2) LH : L. Harra, NL: N. Labrosse, DW : D. Williams, LG : L. Gesterlyi EUS - Science, JCV,RAL, March 2006

  7. HRI coronal proposals (3) FB : F. Baudin, GDZ : G. Del Zanna, SM : S. Matthews EUS - Science, JCV,RAL, March 2006

  8. HRI/FSI coronal proposals (4) FA : F. Auchère, SM : S. Matthews, SP : S. Parenti EUS - Science, JCV,RAL, March 2006

  9. Solar Orbiter Summary (1) All need high resolution Interest for co-rotation (long-term observations (AR), oscillations, correlation with in-situ, ...) Interest for polar observations Quite universal interest in velocity measurements : Range ? Wavelengths , .... Issue of pointing/tracking specific features (AR, ..) EUS - Science, JCV,RAL, March 2006

  10. Solar Orbiter Summary (2) HRI : Need for cool, hot and (for micro-scales programs) very hot lines Interest expressed in spectro-imagery (MOSES-type): essentially in 30.4 nm FSI : Context for EUI and EUS observations But also specific programs (large-scale structures, oscillations, ..) 17.1 (or 19.5 nm) Interest for a second (cool) line EUS - Science, JCV,RAL, March 2006

  11. Solar Orbiter EUI December 2005 meeting HRI : imaging only Lalpha channel ? FSI : one or two wavelengths ? Spectro-imagery (Moses-type) ?? EUS - Science, JCV,RAL, March 2006

  12. Solar Orbiter Actions Getting the community involved : Call for contributions : to be issued Attached document (+ www) http://www.ias.u-psud.fr/tpl2page.php?pageID=702 providing a template for proposals providing a Table from Photometry WG establishing a continuous link between the consortium and the community, including news about the output of their inputs EUS - Science, JCV,RAL, March 2006

  13. Solar Orbiter Conclusions For a proper definition of EUI : * Continue the work on science priorities, adressing issues such as : What the SO priorities within the SO objectives ? What is unique in SO as compared with STEREO, SolarB and SDO ? Some common wavelengths with EUS ! * Take into account the instruments / S/C capabilities (compression, photometry, pointing/tracking of AR, ...) * Build 15 days of observations scenarii (taking into account TM rates vs. distance to the Sun ) EUS - Science, JCV,RAL, March 2006
