This image show visible-wavelength speckle image reconstructions of Jupiter taken on July 18 1994 at 04:52 UT.
Dark spots are clearly visible at the impact locations of comet fragments C, A, and E (or, possibly, F), These spots can be seen in the top portion of the image (C on the left, E on the right). As shown, the images are in the same orientation as they were acquired, with the south pole up and east on the left. The spots are approximately 1 arc second in diameter, and impact sites A and E appear to have ring structures surrounding them.
The image was taken with the following parameters:
Wavelength: 550 nm Bandwidth: 40 nm Plate scale: 0.063 arc-sec/pixel Size: 750 x 750 pixels (appx 47 arc-sec x 47 arc-sec) Exposure time: 250 ms No. of frames: 40
The images were processed using a speckle bispectral reconstruction algorithm. Each image shown combines the information from 40 short exposure frames taken over a total time of 2 minutes.
