    Dear all,
    
    Here is something to look forward to:
    ESA's comet chaser ROSETTA is going to make a earth flyby on march 4th.
    Perigee is at 22:09:28 UTC, about 2000 km above the southern tip of 
    Baja California. Best visibility should occur an hour earlier from
    Africa and Europe, where the probe will be high above the horizon at
    a at least 10th mag. 
    In order to enable amateur astronomers to observe the flyby, ESA provided
    up to date orbit information to the people of the JPL Horizons system, 
    
    http://ssd.jpl.nasa.gov/cgi-bin/eph   
    
    In the nights before, visibilty is favourable almost anywhere on the 
    planet since Rosetta will be approaching from the opposite side of 
    the sun. Since the spacecraft will be quite faint during the approach,
    a CCD equipped telescope should be necessary to observe it. 
    Please find attached links to a groundtrack plot and tabular data 
    describing the flyby. Both files were kindly provided by Trevor Morley 
    of ESA/ESOC.
