SOT: polar chromospheric dopplergram

2007-07-26T01:13:30 to 2007-07-26T10:48:10

Science Goal: polar chromospheric dopplergram

Program: H-a 2 wave for DG, CaH2Kx2K 2x2, 30s

Target: North pole

xcen=0 ycen=930

Instrument: SOT

HOP/JOP: 0

Description: Daily Note and User Entry: EIS: Would like polar coronal hole pointing for co-observing with XRT and SOT. Two programmes are being considered. 1) Slow context raster then fast sit'n'stare slit observations at several positions for short-timescale dynamics. 2) Jet dynamics with 40"" slot sit'n'stare observations EIS will perform MHC software upload toward end of this week. For programme 2 we suggest SOT fast SP maps to observe changes in the photospheric field, and XRT single-filter, high-cadence observations to complement EIS temperature coverage. SOT: Support HOP10 Norikura and HOP24, which observes prominences and filaments at limb. andnbsp

We may try tests for H-alpha dopplergrams, and H-alpha flat field imaging in the quiet sun. SOT: Memory upload operation to load new frame definition tables in FPP memory.
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.
