    Derek Breit, Russell Eberst, Kevin Fetter, Alberto Rango, Greg Roberts,
    Peter Wakelin, Mike Waterman and Brad Young, contributed observations used
    to determine one or more of the following element sets:
    
    Russell observed the elusive 80019A, 55 days after it was last observed,
    about 84 s late relative prediction; here are Mike McCants' elements:

    Russell has recovered 03009A, nearly six months after it was last observed;
    here are Mike McCants' elements:

    Kevin has observed two of the Essaim satellites. The following elements are
    approximate.
    
    Essaim 3                                                 651 X 665 km

    Russell reported the first observation of 05042A in 32 days; here are Mike
    McCants' elements:

    Russell has made the confirming observations of his discovery of 09066A. The
    orbit is a bit higher than I had guessed, and its ground track does not
    repeat daily.
    
    IGS 5A                                                   584 X 585 km

    Mike McCants observed WGS 3 several days ago, at its check-out location near
    121.85 W, and Brad observed it last night, near 121.87 W.
    
    WGS 3                                                35784 X 35792 km
