Re: (meteorobs) Sporadic Flux Variations
Lew,
Well my intuitive guess would be that it consists of the flux of dust that
has settled near the plane of the solar system. The regular "ecliptic"
showers (Sagittarids, Taurids, etc) are what we plow into with our
revolutionary motion around the sun (mostly medium velocity as we perceive
them). The rest of the junk that hasn't settled into the plane yet (
retaining cyclical motion up and down or in and out still disapating it's
initial heliocentric motion) will have a location and velocity distribution
in a near Gaussian curve relative to this...And I believe it fits the
general profile of sporadics. Well that's what my brain came up with.
Anyone who knows what they are talking about care to give their opinion?

Thanks, Jim! Your summary of the currently available data was really
concise,
and helped clear up some of the questions which even the IMO Handbook
didn't
make entirely clear for me.
But I still have one question for the list: what are some of the hypotheses
which are being tested to explain the late-year peak in sporadic rates? And
how
are visual observers' data being used to test these theories?
A related question, I guess: where DO the various materials which make up
the
"sporadic background" originate from? Any takers on these questions?
