Numerous reports on astronomy websites and even mainstream media
have claimed in recent days that the number of Taurids seen this
year is higher than "usual". While www.imo.net has ZHR profiles
for both Taurid streams and all the individual observers' reports,
I haven't seen an "obvious" graphical representation of the
average brightness distribution, esp. compared to other years.
Or an analysis concluding by how much the distribution is different.
Thus the level of confirmation of the "swarm year" hypothesis is
not clear to me.

I don't think the enhancement is necessarily in the ZHR numbers . . . rather
the fact that
this is a "swarm year" suggests that there would be a greater preponderance
of
brighter Taurids and fireball meteors making up the normal 5-15/hr. for the
two streams (Northern and Southern). In a non-swarm year, the rates would
still be in the 5-15 range, but with fewer bright meteors. That's at least
how
I have interpreted it.
