Description:
Tim File-OBS_DEC: Monitor CCD with G-band
Daily Note: none
Request to XRT HOP Number 0029: XRT (Hinode/XRT -- campaign contact: Kathy Reeves): --- XRT observations will be of the form of basic main observation loop over a target-focused FOV, with less frequent context observations including full-disk images. Main Loop: Filters: Al/poly (8-16 sec exposure), Ti/Poly (16-23 sec exposure) Cadence: ~1.5 min for whole loop FOV: 768""x384"" Context Observations: Al/poly (2048x2048, 2x2 binned), 5 thin Be (768""x384"" 23 sec) every ~30 minutes For both types of observations, cadences will be reduced as required to protect the CCD if there is an active region on the disk during the observations.

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.
