    I estimate the following orbital elements, assuming launch on 2006 Feb 10, at
    21:00 UTC - the start of a 6 h launch window:
    
    Falconsat 2 r    3.4  1.7  0.0  6.6 d
    1 72050U          06041.87777778  .00000000  00000-0  00000-0 0    06
    2 72050  39.0000 253.2748 0073000  70.0000 305.0000 15.39500000    07
    
    The orbit crosses the U.S. west coast about 22 min after launch, near 39 N. It
    crosses the east coast 9 min later, near 33 N. A launch delay of several hours
    would result in a pass during evening twilight for parts of the U.S.A.
    
    According to this document, the 2nd stage will perform a second burn at T+1576
    s, about 26m16s after launch:

    Based on the above elements, it will occur over approximately 38 N, 105 W.
    
    I estimate the 2nd stage will reach about magnitude 4 on a good pass. Its tiny
    Falconsat 2 payload (a 35.6 cm cube) will be difficult to observe even with
    large binoculars.
