  A formal report of our work intended for a refereed publication is in preparation. This represents a departure from the usual application of the speckle camera at the USNO. A PostScript version of the abstract is available. Also available is an MPEG of the event. The MPEG is of fifty-three autocorrelations of the mutual event, taken about every five minutes. The image quality and scaling of the images varies due to changes in seeing and the number of exposures comprising each image (limited due to motion). The motion is of Europa relative to Io.
