 As almost all re-entries are of objects that circularise their orbits
 before entry, I would have thought that even faint re-entries of dust
 would last some considerable time and have a very slow onset.  However
 I've seen nothing specific on this.  It would not surprise me that the
 small dust re-entries disintegrate at higher altitudes without a visual
 meteor?  Personally, I'd discount anything shorter in duration than about
 20 seconds as a re-entry, especially if it was bright.

I agree.
