From Obj 4 meeting
This SOOP was inspired on the discussion about Global Helioseismology needs during the Objective 4 meeting in MPS, Göttingen (Oct 2016).
Proposed SOOP Coordinators
M. Roth, J. Hirzberger
Default SOOP duration: 10 days (TBC)
Pointing requirements: Disk Centre
Triggers: none
Description
SOOP designed for global helioseismology with PHI/FDT only. The PHI configuration is currently designed to fulfil helioseismology needs for far side imaging - to detect modes passing through the solar core - and for deep focussing. Note that the specified PHI mode is not (yet) part of the predefined PHI modes.
Instrument | Mode | Comment |
---|---|---|
PHI | PHI FDT at 1 min cadence, processing to v_LOS only TBC by PHI that the new mode PHI_globalseismology_FDT_3 (4x4 binning!) does the job. | Images compressed by binning to 2x2 or cropping when farther away from the Sun. Higher compression may possibly be acceptable for far side imaging. |
SAP objective | Target | Duration | Opportunity (e.g., orbital requirements, solar cycle phase, quadrature ...) | Operational constraints | Additional comments |
---|---|---|---|---|---|
4.2.3 Probe the structure in deep layers of the Sun - Deep focussing | Full Disk | several days (e.g. 3 days) | Earth (SDO/HMI) - SC angle between 45 and 60 degrees | 10-15Mm resolution, i.e. 2x2 binning at perihelion or cropping further out | |
4.2.3 Probe the structure in deep layers of the Sun - Far side imaging to detect modes passing through the solar core. | Full Disk | As long as possible, 60 days would be ideal but may not be feasible | Earth (SDO/HMI) observations in combi with PHI observations at far side: angle 150 to 210 degrees. | Low resolution, v_LOS only but 1min cadence. Compression can be quite high (TBC how high). | |
