Unusual Configuration of Jupiter's Satellites

Jupiter's satellites are normally pretty much in a straight line, but occasionally the outer satellite - Callisto - can appear well to the north or south of the planet. The illustration below shows an interesting "triangular" satellite configuration which occurred at about 03:25 UT on November 5th, 1998:

At this time, Io was alone to the east of the planet, while Europa, Ganymede, and Callisto formed a small "triangle" to the west of the planet. This only lasted a few minutes, as can be seen by setting the time palette to an interval of 5 minutes and moving the time backward or forward.
