COMET P/2007 H3 (GARRADD)
     G. J. Garradd reports his discovery of a comet on CCD images
obtained with the 0.5-m Uppsala Schmidt at Siding Spring (discovery
observation tabulated below), the object showing a faint tail 15"
long in p.a. 10 deg on the 30-s survey exposure.  Following posting
on the Minor Planet Center's 'NEOCP' webpage, N. Teamo and S.
Hoenig report that their CCD frames taken with a 0.41-m f/8
reflector at Punaauia, Tahiti, on Apr. 23.3 UT show a 4" coma and
an 8" tail in p.a. approximately 35 deg.

The available astrometry (including prediscovery Siding Spring
observations from Mar. 28), the following preliminary elliptical
orbital elements, and an ephemeris appear on MPEC 2007-H55.

SUPERNOVA 2006jc IN UGC 4904
     T. Minezaki, Y. Yoshii, and K. Nomoto, University of Tokyo,
report the following near-infrared photometric magnitudes of SN
2006jc (cf. IAUC 8762; http://www.astronomerstelegram.org/?read=961)
using the multicolor imaging photometer mounted on the MAGNUM 2-m
telescope:  Apr. 9.43 UT, K = 16.2 +/- 0.1; 10.40, H = 17.8 +/- 0.1;
10.43, J = 19.5 +/- 0.3.  Limiting optical magnitudes 3-sigma upper
limit:  Apr. 9.43, V = [22.5; 10.40, R = [22.5; 10.43, I = [21.7.
     K. S. Kawabata, Hiroshima University; K. Maeda, Max Planck
Institute for Astrophysics; M. Tanaka, N. Tominaga, and K. Nomoto,
University of Tokyo; and T. Hattori, National Astronomical
Observatory of Japan, report that optical imaging and PSF
photometry of the peculiar type-Ib supernova 2006jc was performed
with the Subaru 8.2-m telescope (+ FOCAS) on Apr. 10.3 UT, yielding
magnitudes B = 24.0 +/- 0.1, V = 23.4 +/- 0.2, and R = 23.3 +/- 0.2.
