    Kevin Fetter's NOSS like unknown from July 4th was observed by me
    yesterday. Multiple orbits can be fitted to his and my data; the orbits
    provided here differ by the number of revolutions that have occured during
    the 12.8 days between the observations. They range from 170 revolutions for
    an orbit with 13.26 revs/day, to 182 revolutions for an orbit with a mean
    motion of 14.20 revs/day. Orbital solutions are possible beyond this range,
    but the residuals of the fit are less good and NOSS like objects typically
    do not have mean motions beyond that.
    
    >From the estimates below the 79174 elset fits best so is a good starting
    point, though ideally a planar search would be the best approach to find
    the object.
