COMET C/2000 O3 (SOHO)
     Further to IAUC 7472, D. Hammer has provided measurements of a
comet detected by the SOHO C2 and C3 instruments and found by J. D.
Shanklin via the SOHO website.  The reduced measurements and orbits
by B. G. Marsden, together with a search ephemeris, are given on
MPEC 2000-Q09.  G. J. Garradd, Loomberah, N.S.W., reports that his
search for this object around Aug. 21.4 UT, out to about 0.5 deg
ahead of its predicted position, yielding nothing to mag about 18.

COMETS C/2000 P1 AND C/2000 P2 (SOHO)
     Hammer also reports the measurements of two more Kreutz
sungrazing comets found by M. Boschat in SOHO C3 website images,
with the discovery positions given below.  MPEC 2000-Q08 contains
the reductions and orbital elements by Marsden.

     Following the recoveries of the 1999 satellites of Uranus (cf.
IAUC 7447, 7450, 7473), permanent designations (and names) were
approved at the IAU General Assembly in Manchester, England:
Uranus XVIII = S/1999 U 3 (Prospero), Uranus XIX = S/1999 U 1
(Setebos), Uranus XX = S/1999 U 2 (Stephano).

     At the meeting of IAU Commission 6 in Manchester on Aug. 15,
Brian G. Marsden announced his retirement, effective the next day,
as Director of the Central Bureau.  His place was taken by the
undersigned.  Marsden had been in charge of the Bureau since Jan.
1968.  In recognition of his long service, he has been given the
honorary title of Director Emeritus, and it is anticipated that he
will still be actively involved in the Bureau's activities.  He has
also been elected President of Commission 6.
