COMET C/2008 J5 (GARRADD)
G. J. Garradd reports his discovery of a comet with a 40" coma
and a broad 20" tail toward the southwest on CCD survey images
obtained with the 0.5-m Uppsala Schmidt telescope (discovery
observation tabulated below). Following posting on the Minor
Planet Center's 'NEOCP' webpage, C. Jacques and E. Pimentel (Belo
Horizonte, Minas Gerais, Brazil, 0.30-m f/3 reflector) write that
their CCD images from May 4.3 UT show a condensed coma 30" in
diameter. J. C. Pelle found a diffuse coma of diameter 20" with a
bright central condensation and a faint tail 20" long in p.a. 220
deg on images taken on May 14.54-14.57 by N. Teamo with a 0.41-m
f/8 reflector at Punaauia, French Polynesia. R. Ligustri
(Talmassons, Udine, Italy) found a 24" coma on stacked CCD
exposures obtained remotely with a 0.25-m f/6 reflector at Moorook,
South Australia, on May 14.74-14.76.

The available astrometry, the following preliminary parabolic
orbital elements, and an ephemeris appear on MPEC 2008-J76.
COMET P/2008 J2 (BESHORE)
Additional observations have shown this comet (cf. IAUC 8941)
to be of short period; the following orbital elements are from MPEC
2008-J68:
T = 2008 Apr. 24.018 TT Peri. = 143.165
e = 0.27988 Node = 97.432 2000.0
q = 2.45485 AU Incl. = 10.622
a = 3.40895 AU n = 0.156593 P = 6.29 years
Visual total-magnitude and coma-diameter estimates: May 7.43
UT, 14.1, 0'.3 (A. Hale, Cloudcroft, NM, 0.41-m reflector); 9.97,
13.0, about 1' (M. L. Paradowski, Dabrowa, Poland, 0.20-m reflector);
12.07, 12.7, 1'.2 (J. J. Gonzalez, Leon, Spain, 0.20-m reflector).
