This SOOP describes a coordinated observation of all high resolution RS instruments, running at highest resolution and variable but high cadence, for a short period of time.
As a planning scenario, we propose to run this SOOP at every perihelion window where we have some extra TM to spare, or where the campaign would fit without sacrificing too much of the rest of the orbit.
This SOOP can be run for different targets, also at plain disk centre, as it is aimed to discover new physics and compare high cadence dynamics in all kinds of solar regions.
Ideally, we would like to observe the same active region close to the disk center and at the limb. This will probably be not possible, so two active regions (one close to the disk center, one at the limb) should be observed. The ideal duration would be 1 hour for each pointing, i.e. 2 hours of observations in total. If this is too much telemetry-wise, then we could perhaps go down to 30 minutes of continuous observations for each pointing, but 10 minutes sounds too short.
Default SOOP duration: 1 hour (can be repeated several times when it fits)
Pointing requirements: may be run at disk-centre or off-pointed
Observations requirement (baseline)
HRI high res / high cadence modes, depending on target:
(currently modelled with AR mode with default cadence (1&2s), 5400kbps )
QS and AR mode, as defined now, generate at 4600-5400 kbps. (i.e about 250x EIDA rate)
In most extreme case, i.e. Discovery mode, HRI would generate 543MB per 10 mins SOOP duration.
We download all generated data.
|PHI_nominal_HRT_0 for HRT||In mode 0, PHI generates at 1607 kbps (about 80x EIDA rate)|
|SPICE||Depending on science goal, but SPICE Waves mode for highest resolution sit-and-stare, |
SPICE 30"-wide Movie if you want more spatial information
|In Waves mode, SPICE generates at ~50 bkps (about 3x EIDA rate). Model as SPICE Waves mode for SAP v0.|
|STIX||STIX Normal Mode|
|Metis||Metis FLUCTS mode at highest cadence (1s) (METIS special modes)||Only if disk centre pointed! |
The detection of high frequency fluctuations in the extended corona would be a new result.

Duration for EUI observations depend on mode: discovery mode may not run long but can be combined with other mode like A or Q.
EUI/HRI-LyA preferred over HRI-EUV.
