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. 2008 UT R.A. (2000) Decl. Mag. May 13.73380 22 28 50.70 -42 14 48.1 16.7 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).
