    Hi,
    
    The candidates are Iridium 7, 8, 11, 20, 47, 57 depending on the exact time.
    Because of the orbital inclination many satellites are at those northern
    latitudes at the same time.
    
    Is there someone with the program COLA that could find which are the
    satellites involved ?

    Two satellites collide in orbit

    In an unprecedented space collision, a commercial Iridium communications
    satellite and a presumably defunct Russian Cosmos satellite ran into each
    other Tuesday above northern Siberia, creating a cloud of wreckage,
    officials said today.
    
    The international space station does not appear to be threatened by the
    debris, they said, but it's not yet clear whether it poses a risk to any
    other military or civilian satellites.
    
    "They collided at an altitude of 790 kilometers (491 miles) over northern
    Siberia Tuesday about noon Washington time," said Nicholas Johnson, NASA's
    chief scientist for orbital debris at the Johnson Space Center in Houston.
    "The U.S. space surveillance network detected a large number of debris from
    both objects."
