Observation Details

SOT: spicules and jets

2007-07-24T01:22:01 to 2007-07-24T18:29:33

Science Goal: spicules and jets

Program: Ca H Very high cadence

Target: North pole

xcen=935 ycen=100

Instrument: SOT

HOP/JOP: 0

Description: Daily Note and User Entry: EIS: Limb observations, for 7 hours, once at east limb, once at west limb, for absolute wavelength calibration. These should be performed on the same day or on consecutive days. We suggest that this takes after the first synoptic of the day, during the longest inter-synoptic gap. SOT: Support HOP10 Norikura and HOP 24, which observes prominences and filaments at limb. andnbsp
andnbsp
andnbsp
andnbsp
We may try tests for H-alpha dopplergrams, and H-alpha flat field imaging in the quiet sun. XRT: CCD Bakeout probably from Monday evening till Tuesday evening. andnbsp
Dark calibration routines before and after. andnbsp

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.
