EIT points out that there will be a EIT synoptic set during that time (13:00 -13:23 UT). EIT observing polar plumes and microjets from 21 - 22:30 UT at the South Pole. Taking 195 Angstrom images with 1 minute cadence. LASCO will be doing jet studies in C3 towards the end of next week. The following information was received from Steve Suess concerning the Ulysses-Sun-Earth at 90 Degrees, Joint CME Observations. (Received after the planning meeting but is included for distribution..): On day 146 of 1997 (26 May 1997) the angle between the positions of Earth (SOHO) and Ulysses will be 89.8 degrees (I'm not sure at what time during the day). The precise angle will be determined later from the orbital data I receive on the Ulysses data files. On day 146, Ulysses will appear to be off the EAST limb of the Sun. On day 146, Ulysses will be 10.5 degrees north of the heliographic equator, at a distance of 5.08 AU. On day 146, Earth will be 1.4 degrees south of the heliographic equator, at a distance of 1.01 AU. With luck, this is accurate information. See you next week, - Steve Suess 5. MEDOC Campaign (Detailed programs) -------------------------------------- Notes by Bernard. Cougrand and Jean-Claude Vial 5.1. Scientific contents JOP9: The scientific objectives concern the diagnostic of prominences/ filaments. Prime targets are quiescent prominences of the polar crown. The programs on SOHO have been updated and they take into account the important contribution of Ground-Based Observatories. They are more focused on density and temperature diagnostic; velocity fields at different temperatures; oscillations. Observing times: 7-12 UT, knowing that THEMIS core observing time will be AROUND 8-10UT. Target selection: it will be defined on the day before. Bright points: Diagnostic (Temperature, densities, etc) of the bright points using different lines formed a different altitudes, and ratios of lines sensitive to the temperature and density. Test filament/VLA: Simultaneous observations of a filament in UV with SOHO and in microwave range with the VLA, and diagnostics 5.2- Operating modes 5.2.1.CDS: JOP9: EJECT_V3 (6 lines, exposure time of 16 s); POBS1_2 (13 lines but higher exposure time); MOVIE mode. Modes 1 and 3 should coincide with measurements made with the Italian filter on THEMIS. Bright points: BPIAS VLA: LARGE_BP, PY24W 5.2.2 SUMER: JOP9: The MEDOC campaign begins on May 20th at 00.00UT, thus it is planned to switch the SUMER master base on Monday morning at 6.00 UT. With the experience gathered in November and January, new or improved modes are tested: Lyman continuum and high Lyman lines; Lbeta and O VI lines; and -if possible- Lalpha out-of-limb measurements in conjonction with CaH (Hepsilon) on the GCT (see below). The daily SUMER observations will start with an He I 584 sequence which will enable us to superimpose the SUMER slit upon the CDS image in the same line. BP: HI_TIME_RES 5.2.3.EIT: Frequent He II 304 images in subfields of about 8*8 arcmin. 5.2.4.UVCS: weeks 21 and 22 will be mainly devoted to other targets but for week 23 (and 24?) a participation of UVCS is now under discussion with J. Kohl, E. Antonucci, S. Fineschi, G. Peres for UVCS. The idea is to obtain Lalpha ( and beta, etc..) spectra in a prominence and/or the coronal cavity above. 5.2.5.MDI: provides a magnetogram every 96 minutes. 5.3. GBO Coordinated observations 5.3.1.JOP 9: THEMIS: IPM filter switching between Halpha and D3: we propose 8-9 UT: D3 and 9-10 UT: Halpha (see below) GCT: E. Wiehr : Two modes: Ca II (8542)/Hbeta and Ca II H Pic-du-Midi coronagraph: Halpha Wroclaw coronagraphs: Halpha Ondrejov spectrograph: multi-lines (Balmer series) Sibizmir is also involved 5.3.2.Test filament/VLA: VLA: (2cm - 21cm) contacts on May 19, 20 and 21 6.
