XRT: Active region tracking across disk
2007-05-07T05:43:54 to 2007-05-08T09:50:00
Science Goal: Coordinated Campaign Observation with THEMIS - a. Filament/prominence study, b. Evolving 3D Magnetic Field in Active Regions
Program: AR_on_disk_5
Target: AR
xcen=0 ycen=0
Instrument: XRT
HOP/JOP: 0
Description:
Tim File-OBS_DEC: AR - Microflares and Topology - Ti/Poly, Thick-Al, Thick-Be, G-band - context + 512 + coalignment
Daily Note: XRT: Active region observations
full-res full-disk images during EIS cal. EIS: STEREO joint observations from 5/4 to 5/17 Include co-alignment program (2hr for N-limb, 2hr for E-limb) in the weekend plan, unless conflicted with science programs. andnbsp
Updated 4 May: Conflicts with large AR tracking
instead will continue AR tracking, and add XRT Full frame G-band images. EIS: Calibration run (3.5 hrs) on QR near disk center at start of OP period. SOT to do QS EFR search during this time.
Request to XRT HOP Number 0004: a. series of 512x512 images in several filters for the duration of the campaign (one week) b. obs of both active regions and plage areas, full resolution at moderate cadence, for comparison with THEMIS magnetic observations.
Other Instruments: a. TRACE, MDI, CDS and EIT
Scientific Objectives: a. Scientific Objectives: i) to study the magnetic topology of the filament in the region near the ""barbs"". ii) magnetic causes of filament
eruption, in particular to observe the background fields and the weak fields near fimaent feet, to determine whether the eruption is due to reconnectoin in the lower or upper atmsophere or whether it is a global loss of equilibrium. iii) relation between photospheric flows and prominence eruption, by determining the
short and long-term evolution of the rpominence in conjunction with measurements of local evolution of minor polarities. iv) prominence thermal structure, to determine basic physical properties of the prominence-to-corona transition region. b. Scientific Objectives i) to estimate the evolution, distribution and neutralization of electric currents in active regions. ii) to quantify the transition from force-free to non force-free regime as function of height. iii) to obtain a 3D map of the topology of photospheric flux concentrations vs. height into the upper chromosphere in order to provide the international NLFFF team with boundary conditions for field extrapolations.Daily Note: XRT: Active region observations
