Hinode/EIS -- campaign contacts: David Williams, Alphonse Sterling EIS will run different studies, depending on whether we are observing cavities or filaments.
Cavities: Our main plan for observations if we have a good filament cavity at the limb is to choose from among these three basic programs: 1) A combination of the 2" slit study CMEO_SLIT_STUDY and the slot (40" wide slit) study CMEO_SLOT_STUDY. These studies are designed to observe CME eruptions and related phenomena. 2) A 4.5 hour raster which includes several different cool (TR) lines; this study is GAD002_AR_RAST, and would allow us to make deep spectrograms over a fairly large (about 300'') FOV. We hope to be able to determine physical properties of the cavity material, or at least of its bright boundary if we cannot detect the cavity material itself. 3) A spatially-sampling raster, using a 1" slit but with 10" steps. This would take about 45 min to complete and include full spectral information. This study is called QS_ATLAS_OFFLIMB.
We would favor running (1) during the observing Focus Time Period in the hope of observing an eruption, since MLSO and SECCHI/COR1/EUVI (also involved in the campaign; see below) might be running high time-resolution observations. We would perhaps choose to run the longer rasters (3, and especially 2) during the observing Focus Time Period if our best guess says that an eruption is not eminent (e.g., due to lack of rise of the cavity over the previous days - Gibson et al. 2006; S. Martin 2006, private comm.), or we would request that the Hinode team consider running the longer rasters prior to the start of the campaign prime time if there is no conflicting observational target.
Filaments: When a good cavity at the limb is not visible, then we will look at filaments or filament channels on the disk. We would run a selection of the previously-developed filament studies for these observations. |
