2007-07-21T19:20:50 to 2007-07-21T20:00:18

Science Goal: filament evolution

Program: Fast map 200 arcsec, ROI 2

Target: Filament

xcen=498 ycen=571

Instrument: SOT

HOP/JOP: 24

Description: Daily Note and User Entry: SOT: Track AR and observe filament or prominence HOP15 will be tested from 07/18 to 07/22. HOP10 prominence observation. HOP24 filament observation. EIS: HOP10 Norikura 4hour per day if whether is fine in Norikura. (Limb fix) XRT: Support HOP10 if possible. Mike Marsh's AR evolution program (coordinated with TRACE) may be run if possible.
Request to SOT: Observation of Ca H spicules. The sequence that was run previously is used. Widest FOV in the NS direction is desired.
Scientific Objectives: To understand the origin of non-thermal line broadening in coronal emission lines
Other Instruments: Norikura: High dispersion spectra of Fe X6374 and Fe XIV5303 are obtained. High-acuracy Doppler velocity and line width are given. Independent Fe XIV 5303 imaging observations provide high-cadence imaging and Doppler informaiton. Bi-products: andlt
This is the most important for EIS team.andgt
: By the simultaneous observations with Norikura Solar Observatory, EIS line width of instrumental origin is absolutely calibrated. In EIS bandpass there are Fe X lines in the short wavelength band and Fe XIV lines in the long wavelength band. These are calibrated with Fe X 6374 and Fe XIV 5303 emission lines. Norikura Solar Observatory is going to support this campaign observation with a high priority.
