Description
This mode uses HRI telescopes targeting a region of quiet sun. It is most appropriate to be used close to perihelion, near co-rotation.
The mode can be commanded on HRI_EUV and HRI_Lya telescopes independently.

| Observing mode | Target | Instrument | Channel | Cadence | Rebinning | Compression | #Images/h | Data Rate | Data Rate | Max time | |
|---|---|---|---|---|---|---|---|---|---|---|---|
| (nm) | (s) | or subfield | rate | (Gibits/h) | (bits/s) | per orbit | |||||
| EUV Quiet Sun (Q) | Full HRI FOV of quiet sun | HRI_EUV | 17,4 | 8 | 1 | 9.4 | 450 | 14.06 | 4194304.0 | 3 h | |
| LYA Quiet Sun (Q) | HRI_Lyalpha | Ly alpha | 1 | 1 | 18.75 | 3600 |
Maximum time in this mode
TM-hungry mode, limited to 3 hours per orbit = 85% of EID-A allocation (if both telescopes are used), if all resulting TM gets downlinked!
