    Harro, i beg to differ , and I am sure you were writing with tongue in cheek
    The first elset is in the transfer orbit. Because of the rules imposed on 
    the majority of TLE's that the epoch be at the ascending node, the time
    sequence of epochs isnt in the chronological order. this tends to
    happen with any launch to a high or eccentric orbit. It certainly happened
    with the Chandra X-ray telescope. Here are elsets from OIG. The elset number
    is the second to last digit on 2nd line of each elset( counting lines 1,2,3)
