SOT: Coronal hole on disk
2007-07-30T01:03:40 to 2007-07-30T05:25:00
Science Goal: Coronal hole brightness
Program: Gb CaH full FOV 2x2 sum - 1min
Target: Coronal Hole
xcen=796 ycen=-69
Instrument: SOT
HOP/JOP: 10
Description:
Daily Note and User Entry: Note: The time of the 1st contact (MSP1) is earlier than usual. SOT: Support HOP10 Norikura and HOP24, which observes prominences and filaments at limb. andnbsp
andnbsp
andnbsp
andnbsp
Coalignment program run (N-limb, E-limb, 2hour for each) to run in weekend plan. XRT: Stop X-ray observation (and perform CCD bakeout).
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.
