    Description of 2-line elements: http://www.satobs.org/element.html
    
    The observational arcs are short, but there are a reasonable number of accurate
    observations, so I decided to allow all elements except for rate of decay to be
    adjusted in the differential correction. The results are likely to flop around a
    bit, as more observations are made. If the results can be trusted, then the
    initial orbital eccentricity is a bit less that that of the first two NOSS 3
    launches.
    
    If the NOSS 3-2 mission can be used as a guide, the NOSS 3-3 are likely to
    manoeuvre as soon as 5 days after launch, and are likely to complete most of
    their manoeuvres within four weeks of launch.
    
    Weather forecast here for Tuesday and Wednesday is overcast.
