MAJIS Jupiter Monitoring of unusual phenomena
Study of the evolution of unusual phenomena in Jupiter atmosphere, especially in their zonal evolution MAJIS will acquire several “subcubes” with limited number of lines (about 80) as follows:
1. a series of sub-cubes (from 1 to 4) is acquired with the scan mirror to get the coverage of a limited latitude region at all longitudes on the visible side of the planet. Satellite is re-pointed before acquiring each sub-cube
2. the series at previous point is repeated at fixed time intervals (in the order of 1 h, TBC) to monitor the temporal evolution.
Pointing type: YS, Series of OFF-NADIR pointings (‘off-nadir scan mode’)
satellite orientation: HORIZONTAL
160 sec for each sub-cube.
Time between series defines actual temporal sampling and is variable (zero data rate here).
Total duration about 5 h (1/2 of rotation period)


nadir offset


These observations can not be planned in large advance since are intended for unexpected phenomena (plumes, impacts). Planning system must retain the capability to accommodate such requests from SWT within few days. Tranquilization effect to be known.
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)
