Jupiter Central Meridian Longitudes

Script written by Brian Sherrod - ASO
Based on formula and information from
Jean Meeus

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")


Enter the Date and Time to compute Jovian CM longitudes

Enter Date of Observation formated MMDDYYYY: e.g. 01012005
Enter Time (UT) of Observation formatted HHMM e.g. 0341
