This arrow points to the site where the Galileo probe entered the atmosphere of Jupiter, on 12/7/95. At this latitude, the eastward winds have speeds of about 250 mph. The right side shows the 4 enlarged Hubble images of Jupiter's equatorial region, with clouds sweeping across the predicted probe entry sight, which is the exact center of the frame.
