Re: (meteorobs) Nov 9/10 Meteor Observations From California
There was a mysterious object in the sky after sunrise (Wednesday), see:

Could this be a meteor train? It made the local news. I was up 24 hrs
ago, & saw it on TV. (they do a sunrise shot on the weather program).
Last year's Leonids, the activity really was heavy near the horizon
3am-5am. Here is one near morning twilight,

Could the above be *.jpg's be a Leonid?
A while back, there was mention of that rocket-burnup seen in Florida.
I finally got the video scan:
