Jupiter's Great Red Spot

Donald F. Collins
This is the first ever observation of Jupiter's Great Red Spot by the author.  It is also his first construction of an animated image.

Three images were photographed by the WebCam camera with the Arghiere 8 inch telescope, separated by about 20 minutes on Friday night, March 7, 2003.  Notice how rapidly the GRS and other features rotate.  Jupiter spins approximately twice as fast as the earth, which is amazing for a planet about 10 times the diameter as the earth.

The GRS was first observed by Giovanni Cassini in 1665.  It is a rotating storm system that has been in existence for more than 350 years of observations.  Compare that with the duration of a weather storm on the earth!
