Subject: [IMO-News] Leonid Fluxes 1994-1998
Dear colleagues,
A new paper from researchers of the Spanish Fireball and Meteor Network
has been accepted to publish in a next issue of "Meteoritics & Planetary
Science".
The importance of our detailed 1994-1998 analysis of the Leonids activity
focuses in the reconstruction of the stream spatial structure during this
cometary return. We have combined 40 independent ZHR determinations obtained
in the last two centuries with their corresponding orbital geometry.
Initially we placed all ZHR points and the software apply a precise
numerical contorning technique to define the averaged density of the Leonid
stream. We use historical observations obtained after the 1800 return and
the ZHR determinations revised by several authors (see for more details
historical ZHRs revisions Jenniskens 1996; Brown, 1999). The result is one
figure that shows an averaged contour plot with the corresponding Log (ZHR)
isolines.
We inclose below the abstract. For more details please contact us.

ABSTRACT: The Leonid shower was observed in November 1998 worldwide in an
intensive campaign without precedent. During this international effort near
35,500 meteors were reported by members and collaborators of the
International Meteor Organization (IMO) using a standard methodology.
Despite the absence of a meteor storm in 1998, the rich observational data
allows to obtain a detailed unprecedented knowledge of the stream structure
between 1994-1998.
