Lew, as I understand it (which may not necessarily be right), they would be
brighter due to the fact that they penetrate to a lower level in the
atmosphere. Note on the height chart of the IMO handbook (Chapter 1 I
think), that bolide type objects are shown at 10-20 km final elevation.
This makes sense to me , since they would be less likely to be disrupted by
dynamic pressure at altitude, due to slower speed, and stronger structure.
Of course that -7 Leonid I saw the light from must have been a decent sized
fluffy chunk. Of course, it did leave a 7 1/2 minute train, so it had
plenty of material.
