| MAG_DL_LIGHT_ONLY | This observation is introduced to characterise JMAG operations during downlink times where power resources from the SC may be more limited, and where SC attitude is driven by operational constraints.
In this particular observation FIB & FOB fluxgates powered on with FSC as light-only. | JMAG |

| MAG_DL_FOB | This observation is introduced to characterise JMAG operations during downlink times where power resources from the SC may be more limited, and where SC attitude is driven by operational constraints Only MAGOBS is operating. | JMAG |

| MAG_DL_FOB_LIGHT_ONLY | This observation is introduced to characterise JMAG operations during downlink times where power resources from the SC may be more limited, and where SC attitude is driven by operational constraints In this particular observation FOB fluxgate is powered on with FSC as light-only. | JMAG |

| MAG_BURST | Operation of J-MAG in burst mode (measurement at rate of 128 vectors/s) starting 10 minutes before and ending 10 minutes after a predicted crossing of a thin current sheet in Ganymedes magnetosphere (magnetopause/magnetotail current sheet). | JMAG |
|---|
| MAG_CONTINOP | measure the magnetic field in normal mode (at a rate of 32 vectors/s) continuously | JMAG |
|---|
| MAG_CONTINOP_FIB_FOB_LIGHT_ONLY | JMAG mode (FIB FOB Light Only), this mode ensures that while FIB and FOB are collecting science the Scalar sensor also has power to its laser but is not collecting science data. This helps to protect the fibres from radiation damage, necessary for the Europa phase due to its radiation environment. | JMAG |
|---|
| MAG_CONTINOP_FIB_FOB | J-MAG will measure the magnetic field in normal mode (at a rate of 32 vectors/s) continuously with SCA not operating | JMAG |
|---|
| MAG_CALROLL | Campaign of spacecraft rolls to allow calibration of J-MAG magnetic field measurements. J-MAG will take data in gradiometer mode continuously while the spacecraft rolls about two principal axes, in regions where the Jovian magnetic field is >100 nT. Spacecraft rolls about two principal axes. 3 rolls of 360° about first axis at 0.5 rev/hr, then 3 rolls about the second axis (also at 0.5 rev/hr). The spacecraft rotation axes must always make an angle with the ambient magnetic field between 20° and 160°. | JMAG |

| MAG_BURST_FIB_FOB | Burst observation mode without scalar sensor | JMAG |
