Based on formula and information from
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|
|I||877.8169147 (877° 49' 00.00")|
|II||870.1869147 (870° 09' 24.89")|
|III||870.4529147 (870° 27' 10.49")|
In addition, other factors are accounted for to compensate for "light time", synodic period, speed of orbit variations during and between perihelion and aphelion.
