  DESCRIPTION         = "Animated sequence of Medium Resolution Instrument    
    visible CCD (MRI) images showing the upper limb of comet Tempel 1         
    during the final approach of the Deep Impact spacecraft on 4 July 2005.   
    At least four jets can be seen extending from the surface, highlighted    
    against the sky background.  As the horizon shifts with time, the jets    
    approach and (some) pass through the plane of the sky, where they appear  
    brightest.  The sequence runs forward, with the surface seeming to        
    disappear over the horizon, and then backward again, so that looping it   
    makes the nucleus seem to rock back and forth.                            
                                                                              
    The coma and nucleus are displayed at different contrast levels so that   
    the nucleus does not saturate the display.  The images were obtained      
    after the DI impact event (the date and time of each image is given in    
    the upper right corner), so ejecta in the foreground causes the ''sky''   
    to brighten throughout the sequence.  Each image has been rescaled to     
    the same spatial scale and registered to produce a smooth sequence.       
    The section of the nucleus shown is about 3.5 km across.  The white       
    gap at the top of many of the frames is caused by the image of the        
    nucleus getting close to the edge of the CCD.  For more information,      
    see ''Dust coma morphology in the Deep Impact images of Comet             
    9P/Tempel 1'' by Farnham, et. al (2007)."
