Dear George and Pierre,

I don't think so.  I think it is important that some of these fireball
belong to (N)Taurids.  Observers know that (S)Taurids is more active
than (N)Taurids at this time of the year in general, though observers
decided it (N)Taurids.  Therefore, it is probable that these fireball
are (N)Taurids.  But I wonder why (N)Taurids fireball appeared actively.
Would 7:2 mean motion resonance with Jupiter affects (N)Taurid swarm
rather than (S)taurid swarm?
