| MAJ_JUP_STELLAR_OCC | MAJIS will acquire several “subcubes” (number depends upon planet's speed over the sky) around the (fixed) star position, at different angular distances between the star and the planet's limb during the ingress/egress.
Each sub-cube spans over several lines (around 6, less if S/C capability allows it) to compensate for possible pointing inaccuracies.
Bright far moons can be used instead of stars as sources to decrease the repetition integration (and therefore spatial sampling) as the orbital velocity ranges from ~ 5 km/s at apojove to ~ 13 km/s at perijove
satellite orientation: LIMB TANGENT (preferred, otherwise VERTICAL), to minimize straylight

About 10min

| UVS_JUP_SP_SOL_OCC | The large solar disc and the substantial distance from Jupiter mean that this will not provide the same vertical resolution as stellar occultations, but are useful for measurements of minor/trace constituents due to high S/N. This uses a fixed scan through the Solar Port (SP) at a selected RA and DEC, holding the pointing for an extended amount of time. Note: Here histograms, but pixellist mode possible. | UVS |

| MAJ_JUP_LIMB_SCAN | The MAJIS pointing mirror is used to scan the atmosphere of Jupiter over the limb up to 1500km. Exposure times are optimized for weak limb emissions.
The scan mirror step of 1/10 MAJIS IFOV shall constrain the spatial sampling provides a spatial supersampling adequate to reconstruct, by deconvolution, the signal vertical profile at sub-pixel scale.
Observations consists in sets of max. 8 cubes at different latitudes, around the limb of the planet.
Duration: Typically 20 min for each cube (110 lines), assuming 11 s per line | MAJIS |
|---|
| MAJ_JUP_HIGHFREQ_MONITORING | The observing type is designed to study the evolution of atmospheric features at high temporal frequency as well as to map specific atmospheric features at regional scale.
Scanning of features on the Jovian disc, on dayside as well as on nightside, with limited latitudinal coverage.
MAJIS will acquire one or more several “subcubes” with a limited number of lines (about between 64 and 160)
Duration: between 84 and 315 s for each cube, assuming 2.1 s per line | MAJIS |
