XRT: Active region tracking across disk
2007-05-18T10:14:54 to 2007-05-18T10:46:54
Science Goal: CDS/UVCS + Ulysses Campaign
Program: AR_on_disk_1
Target: AR
xcen=0 ycen=0
Instrument: XRT
HOP/JOP: 0
Description:
Tim File-OBS_DEC: AR - Microflares and Topology - Al/mesh, Ti/Poly, Thick-Al, Thick-Be - Ti-poly, Al/poly -20s cadebce - Ti/poly,G-band contexts - 512FOV - AEC123
Daily Note: Weekly Meeting EIS: Would like to run a variety of active region programs. SOT: Ditto XRT: Ditto EIS: 3.6 hours quiet Sun andnbsp
for instrument sensitivity monitoring andnbsp
in saturday's upload plan (timing to be discussed today). Co-alignment program (2hr each for N and E limbs) may be requested to run once every few days, depending on the satellite temperatures and science programs.
Request to XRT HOP Number 0007:
Other Instruments: SoHO/CDS, UVCS
SoHO keyhole starts 17-May (26m dish) and 21-May (34m dish) STEREO/SECCHI Ulysses will be ending the quadrature with SOHO. Ulysses will be at a latitude of 55 deg (south-west), in the plane of the sky. Hence any active region say between 45 and 65 degree south that might be near the limb would contribute to the solar wind measured in-situ by Ulysses. Scintillation measurement (G. Poletto)
Scientific Objectives: The main aim is to measure chemical abundances in active regions as a function of height for 1.0 andlt
R(Sun) andlt
1.6 using SOHO/CDS, Hinode/EIS, SOHO/UVCS, and to link them with in-situ measurements by Ulysses. A secondary aim is to measure electron temperatures, densities, and ionization state of the plasma as function of height from 1.0 to 1.6 solar radii using SOHO/CDS and Hinode/EIS. There have been no previous spectroscopic observations in the range 1.2 and
#8211
1.6 R(Sun).
