EDITORIAL NOTICE
     A new edition--the seventeenth--of the MPC/CBAT "Catalogue of Cometary
Orbits", complete through the entries in the June 2008 batch of the Minor
Planet Circulars, will shortly be available.  Given that the catalogue includes
3815 orbits for 3708 cometary apparitions, it was decided to place the 1490
orbits of comets observed only from SOHO, STEREO, SMM and SOLWIND in a
separate section.  There is also a section giving the 1139 orbits for 1062
apparitions of the 200 numbered comets.  Except for the nine of these comets
that are considered "lost", there are tabulations of the osculating elements
for the standard epochs 2007 Oct. 27.0, 2008 May 14.0, 2008 Nov. 30.0, 2009
June 18.0, 2010 Jan. 4.0 and 2010 July 23.0.  "Original" and "future"
reciprocal semimajor axes are given for 499 high-quality long-period orbits.
The 195-page catalogue sells for $60.00 ($80.00 for airmail delivery outside
North America).  There is also an e-mail edition (with just the basic orbital
information) for $80.00.  Orders should be sent to Mail Stop 18,
Smithsonian Astrophysical Observatory, 60 Garden Street, Cambridge, MA 02138,
U.S.A., iausubs@cfa.harvard.edu or FAX +1-617-495-7231.
