    Brian, looking at Alan Pickup's satellite decay list #112,
    which lists actual decays in last half of january, the only
    re-entries near the date in question Jan 24.02 UT, are 
    1978 26GQ at jan 23.5 UT which is a small piece of debris
    Molniya   at jan 24.99 UT which decayed in Southern hemisphere
    showing that the noise you heard wasnt from man-made debris.
    Bolides are far more frequent than man-made re-entries

    This should have left a signal in the seismic record,
    probably not like an earthquake. Since you have a
    reasonably accurate time can you get the records
    of several stations checked?
