SOT: Co-Alignment

2007-07-17T01:13:10 to 2007-07-17T05:42:00

Science Goal: Co-Alignment

Program: G-band 5 min for alignment and Ca H 15sec

Target: Alignment

xcen=0 ycen=930

Instrument: SOT

HOP/JOP: 10

Description: Daily Note and User Entry: XRT: XRT_FOCUS_RECAL needed. HOP10 support in consideration. Mike Marsh's AR evolution program (coordinated with TRACE) may be run if possible. SOLIS/XRT coordinated observation during 3.5hr EIS Cal run. SOT: track AR 10963 and observe filaments or prominence. EIS: 3.5 hour sensitivity monitoring program to run in the weekend plan on quiet Sun near disk center.(16:00--20:00 UT) HOP10 Norikura 4hour per day if whether is fine in Norikura. (Limb fix) Coalignment program run (N-limb, E-limb, 2hour for each) to run in Monday plan. ********OP starttime is 10:20 (between 2nd and 3rd pass)************************
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.
