Speckle Imaging of Jupiter, 20 July, 1994

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 ( < 0.5 arcseconds).

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.
