MAJIS_MainRING _LowPhase
MAJIS Observations of the main rings under backscattered illumination
Observations of the main rings (2 ansa), no tracking of azimuthal structure, 20 vertical lines

pointing: OFF-NADIR, S/C pointing centered on the extremity of main rings, S/C depointing required for the two ansa

Satellite orientation: Maintaining the MAJIS slit parallel to radial axis of main rings, MAJIS scan mode activated for vertical sampling centered on the rings (20 vertical lines)

Duration:400 sec (excluding the S/C repointing to the other ansae)


nadir offset


Low elevation (<0.2 deg), low phase (<10°), 2 ansa Acquisition at far distance (>8.105 km at closest approach) to mitigate the spikes issue (<1 e- impacts/s) constraining the resolution (IFOV>=120 km before binning) 100 kHz readout mode (lowest RON < 30 e-)
any rule that is used to schedule the observation: repetition rules, continuous (plasma instruments), one-off, every orbit, every day, etc
conditions that make the observation not possible (e.g. thruster firing)
