JupSat Pro is a utility for Win 98/NT/2000/XP which provides a range of information on the Jupiter and graphically displays the planet (including its Great Red Spot) and the positions of its four main satellites, Io, Europa, Ganymede and Callisto (in real time).

It uses the user's geographic location, Timezone and Daylight Savings Time for its calculations, so these must be set up correctly. All times displayed are in local time.

JupSat Pro Main Features:

---

NASA TV screen displays a live video feed direct from NASA (needs a high-speed internet connection)

Jupiter In The News screen displays the latest web-linked news items about Jupiter

General Astronomy News screen displays the latest web-linked news items from the world of astronomy

Links to online resources about Jupiter, its satellites and missions and various radio astronomy resources relating to Jupiter

Calculates times of satellite eclipses by Jupiter's shadow

The Satellite Tracks diagram now matches what would be seen through the selected optics (previously, the diagram showed the tracks as seen through a Newtonian relector)

The Satellite Tracks diagrams can now be printed out

The Great Red Spot Transit times can now be printed out

Calculates and displays the positions of Jupiter's four main (Galilean) moons - Io, Europa, Ganymede and Callisto for any date and time

Displays side-on and plan views of Jovian system

The display can be changed to support the view as seen through different optical configurations

The position of the Great Red Spot is shown for the selected time and date

Shadows of the satellites are displayed crossing Jupiter's disk

The displays can be animated to show the movement of the satellites, their shadows and the Great Red Spot

The displays can be zoomed so as to see satellite phenomena in greater detail

Times of Great Red Spot transits are calculated for the selected month

A diagram of the satellite tracks for the selected month can be viewed

Times of satellite phenomena (Transits, occultations, etc.) are calculted for the selected date

Compass directions show the orientation of Jupiter and its satellites depending on what hemisphere you live in and what optical configuration you have selected

View rotating maps of each of the four satellites

Displays the Rise, Transit and Set times of Jupiter for your location so you can make the most of your observing opportunities

Displays the position of Jupiter (in RA/Dec and Alt/Az) along with its magnitude and distance amongst other data

Numeric distances (in Jupiter radii) for each of the satellites are displayed

Data for satellites that are transiting or being occulted by Jupiter are displayed in different colours for easy identification
