The Usenet reports I saw of this event implied a steep descending
trajectory in the WNW as viewed from Cambridge, MA, and a very quick
motion - hardly promising characteristics for a re-entry.

In fact, I can identify no known unclassified objects with decays within
a few hours of this time. The closest significant decay was #24749, the
Centaur 2nd stage of the Atlas 2a from the Tempo-2 launch (not "Tempo-1"
as stated incorrectly in my current SatEvo decay list), which decayed on
the 18th at around 18h UTC. Decaying on the 17th UT (well before the
fireball) were #24999 (Pegasus debris) and #25015 (Foton N11 debris),
while #23902 (Mir debris) re-entered on the 18th, I think shortly after
the Centaur.
