(meteorobs) Unusual Eta Taurid (ETT) Activity?

[Pierre Martin]

Hello all,

I am curious if the Autumn Arietids reported by George could be an early manifestation of North Taurids?  Especially with the possibility of a strong Taurid fireball swarm return or enhanced rates that may occur this year?

The velocity for the ETT's would be at least 15km/sec faster than what George reported so I believe these two radiants are different.
