    The rate of decay of my previous two 96072A elsets proved too low, as evidenced
    by the object's 0.6 s early arrival when I observed it last night. The two-day
    observational arc upon which they were based, was too short to determine a
    reliable rate of decay. With last night's observations, the arc now exceeds
    three days, and the rate of decay has returned to realistic values.

    Lacrosse 5 was more than 0.3 s late on the two passes I observed last night,
    probably the result of a small manoeuvre. I will wait for more observations over
    a longer arc before updating the orbit.
