Proposed SOOP Coordinators

A. Giunta, C. Owen, J. Hirzberger, D. Berghmans


This SOOP is designed to let the high-resolution RS observations cover a wider area than normal, in particular the SPICE FOV. This SOOP is to be used in particular with a mosaic of pointings, though it does not necessarily need to be. Alternatively it could be used when we point for a limited amount of time (few hours typically) to the most likely connectivity point, within a mainly sun-disk-centred observation.

Default SOOP duration: 3 hours

Pointing requirements: mosaic of offpointing

Triggers: only IS triggers enabled

See SOOP 4a defined for SOWG8 planning exercise.

SPICE (leads)

SPICE Composition Mapping (30mins per map)

  • Slit:  4’’or 6”
  • Exposure time: 180 s
  • number of X positions = 10 (inferred, to maintain 30 minute cadence)
  • Field of View: 1.2 x 11’
    • depending on step size chosen – i.e., not the same as the slit width – this could cover a larger region.
  • Number of repetitions of the study: 6 (one at each position)
  • Observation time: 6.4 hours

Mosaic of 6 positions would take bit more than 3 hours

  • RSwindow - quadrature with Earth:

    SoloHI images Earth-directed blobs, Earth images blobs that will hit Solar Orbiter

  • Daily N-S mosaic driven by SPICE composition maps: 6 positions, 30 mins dwell time at each position
  • Pre-window observations with EUI and Metis desired for coronal context

radial or quadrature alignment with SPP is a plus Does slow and intermediate solar wind originate from coronal loops outside of coronal holes? coronal loops outside of coronal holesfew days
  • near perihelion for resolution & better linkage conditions
  • different phases of solar cycle
  • Mosaic to map larger region (e.g. around AR)
  • Modelling to find best candidate source regions
radial alignment with SPP is a plus How does the heliospheric magnetic field disconnect from the Sun?

  • No labels


  1. Could also run PHI_PDF_MOSIAC during this assuming the timing makes sense.

  2. SOOP ID in SOOP Kitchen = LS4
