Jupiter Sequences Fts Images

The Rooftop Telescope at Yerkes was put to work on January 18th, 2002 for six hours, 2:00 to 8:00 UT.  Print out this page, cut out each frame, and make a flip book movie!   Download these .fts images here, then use the HOU-IP software to analyze and combine images. 

• Which moon is which?  In order of brightness, the moons are Ganymede, Io, Europa, Callisto.  In order of distance from Jupiter, the moons are Io, Europa, Ganymede, Callisto. 

• However, because we are looking at their positions from the side rather than from above, a moon's position could appear to be close when it is really far in front of or behind Jupiter.

• Where are the moons in their orbits?  Which direction is each moving?

• Using the HOU image processing software, add the images all together.  Or add, subtract images in a pattern.
  (Manipulation, Add, Choose Image File...)

• Predict the position of the moons for the following nights!  Sketch your predictions.
