Speckle imagery of Jupiter taken at the Lick Observatory 
120 inch telescope. 

These images were taken at 04:12 UT (21:12 PDT) on July 20,
1994. Three sets of speckle frames were taken in rapid 
succession at different wavelengths: 

                              single
    filter            frame exposure
  550 +/- 40 nm     300 ms           20 frames
  700 +/- 40 nm     400 ms           20 frames
  850 +/- 40 nm     700 ms           20 frames
The total sequence was finished within about 4 minutes 
with the goal of keeping the motion blur due to planet 
rotation within the desired resolution element size of 
the reconstructed image ( Impact sites G and H are 
visible, with L just set over the limb. South is up, east 
is left, so that the planet is rotating from left to right. 

The three color bands are combined into a pseudo-color 
image with 550 nm = blue, 700 nm = green, and 850 nm = red.
