PS:Re: (meteorobs) The Aurigids in 2007: Jenniskens expects a, ZHR of 400+

Hi,

I forgot to mention that I have seen the manuscript of Peter's new book.

I think that this is very FINE and USEFULL and COMPLETE with coverage, 
and with INTERESTING descriptions of his personal observations etc, book !

(okay, that's a bit of  self-propagation, i'm one of the editors:) and in
the 6th issue down there look on the first page - there is an article from
Dr. Jenniskens and Dr. Vaubaillon, approximately equal to Dr. Jenniskens'
yesterday's annoucement.  He also speaks there about his coming book about
meteor showers which shall be available somewhere in september, I think, 
and
which can probably provide more information on the topic.   >>

Jan --

A very interesting article, with very exciting prospects!
I would, however, like to point out a correction, followed by a question,
which perhaps Dr. Jenniskens, Jeremie Vaubaillon or Esko Lyytinen might 
be able
to answer.
First . . . the correction.  The article states that next year's Aurigid
shower will take place three days before a Full Moon occuring @ 02:32 UT on
September 4.  In reality, the shower will peak nearly four days AFTER a 
Full Moon
occurring @10:35 UT on August 28.

As for the question . . . the orbital period being quoted for Comet 
Kiess is
given as ~2,000-years.  However, most reference books (such as Gary Kronk's
Comets -- A Descriptive Catalog) indicate that the period is closer to 
2,500
years.  I plugged the orbital elements for comet Kiess into an orbital 
simulator
on my hard drive (with e = 0.996296) and my computer spit out an orbital
period of 2508.55 years.

Then again . . . what's ~500 years among friends?
:)
