SOT: HOP12 for IHY

2007-08-09T17:15:28 to 2007-08-09T21:59:32

Science Goal: IHY FILAMENT OBSERVING CAMPAIGN: Activity in Filaments and Filament Cavities

Program: Halpha CaH 2Kx2K 2x2, ROI=2, 10sec, Limb Prominence

Target: Limb

xcen=-640 ycen=698

Instrument: SOT

HOP/JOP: 29

Description: Daily Note and User Entry: Two-day OP and table uploads today. HOP12 (22 - 3 UT, can be extended to 6 UT if no conflict). HOP26 (3 or more hrs, between 11 - 18 UT). HOP29, filament, prominence, cavities (18 -22 UT). EIS: 1) EIS would like extended periods of quiet Sun limb pointings for two different programmes a) east limb and west limb pointings for 4 hours at each, within a period of 48 hours for absolute wavelength calibration b) quiet Sun limb pointings (any portion of the limb away from activity or coronal holes) to study the behaviour of line profiles, temperature, and density as a function of radial position 2) HOP 29 (IHY Filaments studies) to run beginning today 3) Will support TOO of a prominence for observations 4) HOP 12 to run once XRT is making observations [EIS will not do QS observations today, due to HOPs and presence of an AR] XRT: CCD Bakeout
Request to SOT: SOT (Hinode/SOT -- campaign contact: Scott McIntosh): --- We plan slightly different settings, depending on whether we are observing on disk (e.g., filament or filament channel), or off disk (e.g., cavity or prominence). - On disk: SP: 1) Prior and after Observing Focus Time Period perform 1"" x 100"" X

length-of-channel spectropolarimetric maps in Fe I 6301/6302 2) During Observing Focus Time Period perform 1"" X 100"" x 100""

repeated rastering of SP. BFI: Alternating at 10s cadence Ca II H (3968.5 Ang) full field (200"" x 100"") of channel region CN I (3883.0 Ang) full field (200"" x 100"") of channel region NFI: Choice of one - maybe we'll be able to tune by then and get both 10s Fe I 6302.5 Ang. magnetograms at 5s cadence (200"" x 100"") H I 6562.8 Ang. line core at 5s cadence (200"" x 100"") - Off disk: BFI: Ca II H (3968.5 Ang) full field (200""x100"") of prominence region, 5s cadence NFI: H I 6562.8 Ang. line core at 5s cadence (200"" x 100"")
Scientific Objectives: Goals: To study filaments, filament channels, and filament cavities in order to (a) understand the time dependent, three dimensional density, temperature, and magnetic structure of filaments and filament channels and cavities (b) study how filaments form (c) study filament activation in the chromosphere and CMEs in the corona to better understand how this process works and how it is related to CMEs. In addition, if the observed structures erupt we will (d) study the evolution of the cavity during eruption, and (e) map the EUV signatures into the coronal structures as represented by the coronagraphs, with the goal of understanding more clearly the structure and manifestations of CMEs in the low corona.
