     Y. L. Qiu and J. Y. Hu, on behalf of the Beijing Astronomical
Observatory (BAO) Supernova Survey, report the discovery of an
apparent supernova (mag about 17.0) on unfiltered images taken on
Jan. 15.9 UT.  SN 2001K is located R.A. = 11h13m56s.06, Decl. =
+12o18'07".8 (equinox 2000.0), which is 6".7 west and 3".0 north of
the nucleus of IC 677.  W. D. Li, University of California at
Berkeley, reports that SN 2001K appears at mag about 16.5 on an
unfiltered image taken with the Katzman Automatic Imaging Telescope
(KAIT) on Jan. 17.4, from which Li measured the object's position
end figures to be 56s.09, 06".6.  Nothing appears at this position
on a BAO image of the same field taken on 2000 Dec. 20 (limiting
mag 18.3) or on a KAIT image taken on Dec. 30.5.

     W. Liller, Vina del Mar, Chile, reports that inspection of 54
films taken from 1982 Oct. 7 to 1985 Nov. 25 (limiting red-orange
mag 10-11) reveals no outburst of V445 Pup.  He adds that,
observing with a CCD and broadband V filter over a period of 6.5 hr
(exposures every 5 min) beginning Jan. 14.115 UT, no detectable
variation (rms +/- 0.07 mag) was found in the brightness of V445
Pup (comparison star GSC 6543.2917, located 2'.7 to the south);
neither did a period-search program reveal any significant result.
G. Masi, Ceccano, Italy, also reports that V445 Pup remained around
mag about 8.7 (unfiltered CCD) between Dec. 31.7 and Jan. 7.0, and
that short-term fluctuations appeared to be absent.

COMETS C/1998 U6, C/1998 V5, C/1998 V6, C/1998 X11 (SOHO)
     Further to IAUC 7562, D. Hammer reports his measurements for
additional Kreutz sungrazing comets found by M. Oates (Dec. comet)
and X. Leprette (remaining comets) in C2 data on SOHO website
images.  The reduced observations and orbital elements by B. G.
Marsden are given on the MPECs cited below.
