Re: (meteorobs) definition of terms
Ive been using for some time the following 2 terms that I learned
formally from Bob L:
1) Wake - the short-lived (approx < 1 sec) trail/tail of a meteor
2) Persistant Train - the longer lived (approx > 1 sec)glow/trail of a
meteor
The only related entry on the IMO page Malcolm notes is the following:
--------------------
Persistent train
Remaining glow due to ionization in the upper atmosphere after the passage
of a meteoroid. The intensity and duration depend on the meteoroid's
atmospheric entry velocity, its size, and its composition. Bright fireballs
occasionally caused trains visible for several minutes.
-----------------------------
Hopwever, there are no def's for train, trail, or wake
