COMET C/2008 P1 (GARRADD)
     G. J. Garradd reports his discovery of a comet on CCD images
obtained in poor seeing with the 0.5-m Uppsala Schmidt telescope
(discovery observation tabulated below), the object described as
being about 10" in size with a faint, broad feature extending about
15" to the west.  Following posting on the 'NEOCP' webpage, C.
Jacques and E. Pimentel (Belo Horizonte, Minas Gerais, Brazil,
0.30-m reflector) report that thirty stacked 60-s CCD exposures
show a condensed coma of diameter 20" on Aug. 14.2 UT.

     2008 UT             R.A. (2000) Decl.       Mag.
     Aug. 13.72362    0 25 59.88   -46 56 35.8   16.7

The available astrometry, the following preliminary parabolic
orbital elements, and an ephemeris appear on MPEC 2008-P66.

     T = 2009 July  2.633 TT          Peri. =  12.615
                                      Node  =   0.118   2000.0
     q = 3.64014 AU                   Incl. =  61.227


COMET P/2008 O2 (McNAUGHT)
     Additional astrometry have permitted orbital calculations to
show that this comet (cf. IAUC 8963) is of short period, the
elements below taken from MPEC 2008-P54.

     T = 2009 Aug.  5.204 TT          Peri. =  42.253
     e = 0.15655                      Node  = 325.529   2000.0
     q = 3.78077 AU                   Incl. =   9.967
       a =  4.48252 AU     n = 0.103853     P =   9.5 years


COMET P/2008 O3 (BOATTINI)
     Additional astrometry have permitted orbital calculations to
show that this comet (cf. IAUC 8964) is of short period, the
elements below taken from MPEC 2008-P65.

     T = 2008 June  4.806 TT          Peri. = 341.527
     e = 0.72567                      Node  =  47.685   2000.0
     q = 2.51228 AU                   Incl. =  32.218
       a =  9.15770 AU     n = 0.035565     P =  27.7 years
