MAJIS GCO-500 limb observations
Mapping of selected areas on the dayside limb at resolutions of about 300 m at different latitudes (~30° in lat/lon from the nadir) to study variability of the exospheric processes (sputtering, photodissociation, sublimation). MAJIS scanning at different latitudes of the diurnal limb; a minimum of 3 (north,equat,south) x 2 (dawn, dusk) positions.
Pointing: S/C limb tracking at locations where the slit is tangent to the limb
satellite orientation: Off-nadir orientation, Slit tangent to the limb
Duration: 600 sec per cube




A minimum of 3 (north,equat,south) x 2 (dawn, dusk) positions. Limb observation from the night side also possible with lesser conflicts with nadir surface observations with the main goal to monitor plume spatial structure (high solar phase angle). High phase angle constraints are the most meaningful for plume observations Synergy with JANUS.
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)
