SUPERNOVA 2000cz IN IC 1535 (Q2000/269)
On 2000 July 29, Mark Armstrong reported to TA that he had
recorded a probable supernova on four images of that date. The
object has been announced on an IAUC as follows:

Guy M. Hurst, Basingstoke, England, reports the discovery by M.
Armstrong, Rolvenden, Kent, of an apparent supernova (mag 18) on
four CCD patrol images (limiting mag 19-19.5) taken with a 0.30-m
reflector in the course of the U.K. Nova/Supernova Patrol on July
29.048-29.108 UT.  From a 60-s image obtained on July 29.981, in
which the new object still appears at mag 18 (limiting mag 19.5),
Armstrong reports the following precise position for SN 2000cz:
R.A. = 0h13m58s.19, Decl. = +48o09'14".4 (2000).  Nothing appears
at this position on four previous images of this galaxy taken by
Armstrong on 1999 Nov. 2 (limiting mag 19), and nothing appears on
second Palomar Sky Survey red (limiting mag 20.8) and blue
(limiting mag 22.5) plates.

W. D. Li, University of California at Berkeley, reports that
SN 2000cz also appeared in images taken by the Katzman Automatic
Imaging Telescope on July 8.5 (mag about 17.7), 17.5 (mag about
17.9), and 27.5 UT (mag about 18.0).  From the image on July 27.5,
Li also measured the following position end figures for SN 2000cz:
58s.23, 14".2, which is 8".4 east and 14".9 south of the nucleus
of IC 1535.
IAUC 7470

Subsequently Ron Arbour, who provided confirmation in response
to an appeal issued by TA, has advised us his confirming image
was obtained on 2000 July 29.89UT. His astrometry gave end
figures of RA 58.43s DEC 09.9".

Our congratulations on this further success by Mark which
is his 12th supernova discovery and the 25th SN found by members
of the UK Supernova/Nova Patrol.

SUPERNOVA 2000cy IN MCG +3-40-2
T. Puckett, Mountain Town, GA; and D. George, Ottawa, ON, report
the discovery of an apparent supernova (mag 19.5) on an unfiltered
CCD frame (limiting mag 20.5) taken with the Puckett Observatory
0.60-m automated supernova patrol telescope on July 26.11 UT.
SN 2000cy is located at:
R.A. = 15h32m14s.75, Decl. = +18o40'22".9 (2000), which is 29".4
west and 5".7 south of the centre of MCG +3-40-2.  The new object
was also present on an unfiltered CCD frame taken on July 28.09,
but does not appear on Palomar Sky Survey images taken on 1992 June
29 (limiting mag about 21.3) and on 1986 Apr. 12 (limiting mag
about 20.2).
