SUPERNOVA 2001K IN IC 677 (Q2001/003)
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 (2000), 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.
IAUC 7565

Mark Armstrong has reported that he independently found this object
on a single exposure for the UK Nova/Supernova Patrol of
2001 Jan 16.20347UT using the 0.30-m LX200 telescope with the Hale
CCD. He sought a follow-up image on Jan 18.02947UT showing it at
magnitude 16.3 (0.40-m C14+ST 9eCCD). He noted it was absent from a
Palomar red image of 1993 Jan 28 to a limit of mag 20.8 and a blue
image of 1996 April 19 to a limit of about 22.5. It was also
missing from his master patrol image of 1999 Dec 2 with a limiting
magnitude of 18.5.

The above IAUC 7565 was issued just before Mark despatched his
his report to TA although he had not read this incoming alert and
the new object did not then feature on the CBAT WWW SNe pages.

This, again, is another useful discovery by Mark on which we offer
our congratulations.
