Once you've seen one (I've been fortunate enough to see four) it's a
sight you won't forget. While observing the Quadrantids about four years
ago, I saw two within the space of an hour, traveling in opposite
directions. I've seen other meteors that seemed to be "partially" nebulous.
Norm's description of nebulous meteors is absolutely dead-on, based on
what I saw. Sure would be nice if someone could put forth a good
explanation for them.
