Who provides probably the very best planetarium software available.
This program will calculate the longitudes for each of the three Jovian systems (I, II, & III) based on the following:
|System||Rotational degrees (in decimal degrees) per day|
In addition, other factors are accounted for to compensate for "light time", synodic period, speed of orbit variations during and between perihelion and aphelion.
