SUPERNOVA 1999dk IN UGC 1087
     M. Modjaz and W. D. Li, University of California at Berkeley, on behalf
of the Lick Observatory Supernova Search (cf. IAUC 6627, 7126), report the
discovery with the 0.8-m Katzman Automatic Imaging Telescope (KAIT) of an
apparent supernova in UGC 1087.  The supernova was discovered and confirmed
on unfiltered CCD images taken on Aug. 12.5 UT (mag about 16.7) and Aug.
13.5 UT (mag about 16.4).  The new object is located at R.A. = 01h31m26s.92,
Decl. = +14o17'05".7 (equinox 2000.0), which is 4".1 east and 26".2 north of
the nucleus.  A KAIT image of the same field on Aug. 7.5 UT (limiting mag
about 18.0) showed nothing at the position of the supernova.

     T. Puckett and M. Marcus, Mountain Town, GA, report their discovery of
an apparent supernova (mag 19.1) on an unfiltered CCD image (limiting mag
20.6) taken with the Puckett Observatory 0.60-m automated supernova patrol
telescope on Aug. 11.32 UT.  The candidate is located at R.A. = 23h04m11s.70,
Decl. = +27o07'07".3 (equinox 2000.0), which is 2".8 east and 8".9 south of
the nucleus.  The candidate was also present on an unfiltered CCD image taken
on Aug. 13.24 UT and does not appear on Palomar Sky Survey plates taken on
1954 Aug. 9 (limiting mag 20.5) and 1991 Oct. 4 (limiting mag. 21.5).

     M. G. Lee, on behalf of the Seoul National University, Department of
Astronomy, supernova search team (Lee, C. Park, J. Lee, S. Lee, C. G. Park),
reports the discovery of an apparent supernova (R mag 18.8) in four R-band
CCD images (limiting R mag 21) taken with the 1.8-m reflector of the
Bohyunsan Optical Astronomical Observatory (BOA) on 1999 June 18.64 UT.  The
object is located at R.A. = 15h22m28s.95, Decl. = +27o42'44".9 (equinox
2000.0), which is 0".8 west and 13".1 south of the nucleus of Abell 2065-164
(Postman, Geller and Huchra, 1998, AJ, 95, 267), and was not visible in CCD
images taken with the same instrument on 1999 Jan. 17.  The supernova was
confirmed on CCD images obtained on Aug. 12.49 UT (R mag 21.2) by Y.-B. Jeon
with the 1.8-m BAO reflector and on Aug. 12.19 UT (V mag 21.6) by M. Bolte
with the 3-m Lick Observatory reflector.  The limiting magnitudes of the
confirmation observations were R = 22.6 and V = 23.1, respectively.
