Occultation of Jupiter by the Moon - 4th October 1998

brought to you by the

Calwell Lunar Observatory


There will be an early evening occultation by the moon of Jupiter and three of its Galilean satellites (the four bright moons), on the evening of 4 October 1998 which will be visible from Canberra if we have cloudless skies. The moon will be near full (97 % illuminated by the sun) and at an altitude of 15 degrees to 26 degrees in the eastern sky. Moonrise is at 4h16m pm and sunset is around 6h10m pm.

Below are some images from the Maris Redshift program showing these events. You are encouraged to accurately time the dis-appearances and re-eppearances of the three satellites and of Jupiter. At the Calwell Lunar Observatory, I will attempt to capture video images of this event with an accurate short wave timing signal - if successful the captured images will be placed on my Home Page.


The satellite Europa will disappear behind the moon just after 5h34m (PM), followed by Jupiter at 5h40m, the satellite Io at 5h43m and the satellite Ganymede at 5h49m. Here are some of these events:

The disappearance of Europa at 5h34m PM


The dis-appearance of Jupiter at 5h40m PM


The re-appearance of Jupiter at 6h39m PM


The re-appearance of Io at 6h43m PM


The re-appearance of Ganymede at 6h49m PM
