    Radio observations show that the orbit was adjusted on April 10 after 18
    days. There seems to have been a minor adjustment two days before.
    
    It put the Mean Motion back to the level normally seen after a major
    correction, but it occurred about 60 percent of the way through a cycle and
    was proportionately smaller in magnitude than a major correction.
    
    Latest plot is here:

    The newest calculated values for Mean Motion are provisional.
