Description

Mobile Jupiter is an application to plot in the screen of your mobile device the relative positions of the galilean moons of Jupiter (Io, Europa, Ganymede and Callisto). Mobile Jupiter is aimed to assist you while observing Jupiter with binoculars or telescopes. This way you will be able to know what are the moons you are seeing in that moment.

Mobile Jupiter is written in Java 2 Platform, Micro Edition (J2ME) and requires a device that support MIDP 2.0 standard.

The code used to compute the positions of the moons was initially based on a Qbasic script of the GALSAT written by Dan Bruton. GALSAT is a DOS program and you can download it here. After some time the code was changed and now it is based on the Java Script applet by Akkana Peck that can be found here.

Mobile Jupiter is an iniciative of Miguel Moreto.

Features

These are the main features of Mobile Jupiter:

• Graphical plot of Jupiter and the galilean moons at the current time;
• The user may specify the date and time of the plot;
• Auto refresh. The position of the moons are updated at time intervals defined by the user;
• Night mode. All the information are showed in red color in order to not compromise the user's vision in dark places.

Planned features

These are the planned features for future releases:

• Event table. The user enters a time interval and Mobile Jupiter returns an event table showing events of the galilean moons like eclipses and occultations;
• Event alarm. The user can set alarms for specific events of the table to alert him for incoming events;
• Plot the orbits and positions of the moons as seen from a top view.
