Roberto,
Thanks for the reply. No need to apologise, your English is excellent.

That's correct I was thinking about the events of one year ago. I found
Jan and Pavel's posts most interesting.
If you and I were fortunate enough to witness another fireball tonight -
both at the same time, so we are sure it is the same event. You plot it
on a star chart between points A and B and I plot it between points C
and D. Neither of us know the radiant, but because we are in different
locations points A and B, C and D will be different. If we exchange
information, our two lines will cross at one point. Is that the radiant?
That seems too simple - no orbital information required, so I guess I'm
missing something. But I can't figure out what...
