COMET P/2005 V1 (BERNARDI)
     D. Tholen, University of Hawaii, reports the discovery of a
comet by Fabrizio Bernardi on images taken with the Canada-France-
Hawaii Telescope (discovery observation below; the observing was
assisted by A. Boattini, T. Burdullis, and M. Laychak, with Tholen
as principal investigator of the University of Hawaii Asteroid
Search project).  The comet shows a very faint tail extending as
much as 12" in p.a. about 290 deg on the discovery images, and the
magnitude was made in a 3".7 photometric aperture.  Images obtained
by H. Hsieh on Nov. 4.6 UT with the 2.24-m telescope at Mauna Kea
also show the tail.  The point-spread function of the comet's head
was consistently about 0".3 larger than stars of similar brightness.

(1862) APOLLO
     S. J. Ostro, L. A. M. Benner, J. D. Giorgini, Jet Propulsion
Laboratory; M. C. Nolan, A. A. Hine, E. S. Howell, Arecibo
Observatory; J. L. Margot, Cornell University; C. Magri, University
of Maine, Farmington; and M. K. Shepard, Bloomsburg University of
Pennsylvania, report that Arecibo delay-Doppler radar observations
of (1862) on Oct. 30 and Nov. 1-2 show that this minor planet has a
satellite whose average diameter is within a factor of two of 75 m
and whose maximum orbital distance exceeds 3 km.


SUPERNOVAE 2005hk-2005in
     CBETs 268 and 272 contain information on 30 supernovae found
by the Sloan Digital Sky Survey II collaboration during Sept. 3-Oct.
23 (communicated by J. Frieman), all in the magnitude range g =
19-23 at discovery.  All are either confirmed or suspected type-Ia
supernovae except 2005hl and 2005hm, which are of type Ib.  SN
2005hk (cf. IAUC 8625) was independently discovered by the SDSS II
group.
