    Hello Brad,
        This observation corresponds to NOSS 2-3(C) 1996-029C followed by
    NOSS 2-3(E) 1996-029E although with magnitudes of 8.2 and 8.7
    respectively it reveals how clear Walcha's skies are. I used CalSky to
    identify these satellites...your friend can confirm this if he wants.
        I am about 150km south of Walcha. You have my email address. If your
    friend wants direct contact or further assistance please feel free to
    pass it on.

    Subject: Please Help ID a Pair of Satellites
    From a friend I met in Australia, I'm just back from a week at a star
    party and no access yet to elements...
    I saw an interesting pairing of satellites the other night in Walcha
    whilst observing. I have no idea what it was, I had nothing showing on
    Heavens Above, maybe you could help??
    It happened around 10:10pm EST (12:10 UT) on the 17th Sept, I was
    looking South-West, if I drew a straight line from Delta Scorpii through
    Beta Lupus and continuing south to just between Beta Centaurus and Beta
    There were 2 brightish (mag 2) satellites, separated by 30 to 40”
    travelling from West to South along the line I mentioned.
    The satellite trailing the first brightened to about mag -1 for a period
    of about 30 seconds or so, this is what drew me to the satellites.
    I could only assume that they were chasing each other, one friend on the
    SCP forum suggested it might be a Japanese orbiter chasing the ISS, but
    I had no ISS predictions on Heavens-Above.
    My location was my regular observing site S 31 00’ 23.4” ; E 151 33’
