SUPERNOVAE 1999dc, 1999dd, 1999de
A. Gal-Yam and D. Maoz, Tel Aviv University, report for the Wise
Observatory Optical Transients Search, report their discovery of
apparent supernovae on unfiltered CCD images taken by Gal-Yam (with
A. Daniel on July 11) using the Wise Observatory 1-m telescope:
SN       1999 UT      R.A.  (2000.0)  Decl.    R     Offset
1999dc   July 10   14 44 08.80  +58 53 31.6   19.3     --
1999dd   July 10    0 27 31.06  +21 42 47.0   21.1     --
1999de   July 11    0 22 28.20  +23 23 56.2   21.2   4".0 W, 4".8 N

Editor: SN 1999db although announced on IAUC 7227 as found by this
same group, has now been rejected by T.Matheson as its CCD spectrum
suggests it is a QSO. (IAUC 7228)

SUPERNOVA 1999df IN CGCG 274-026
T. Puckett and I. Siegert, Mountain Town, GA, report the discovery
of an apparent supernova (mag 18.2) on an unfiltered CCD frame
(limiting mag 20.0) taken with a 0.60-m automated supernova patrol
telescope on July 20.16 UT.  SN 1999df is located at R.A. =
15h08m56s.52, Decl. = +52o26'53".1 (2000), which is 5".9 north of
CGCG 274-026.  The new object was also present on an unfiltered
CCD frame taken on July 21.09, but it was not present on an
unfiltered CCD frame taken on June 8.17 (limiting mag about 20.5),
nor does it appear on a second-generation Palomar Sky survey image
(limiting mag 20.7) taken on 1991 April 19.

SUPERNOVA 1999dg IN UGC 9758
M. Modjaz and W. D. Li, University of California at Berkeley,
on behalf of the Lick Observatory Supernova Search, report the
discovery with the 0.8-m Katzman Automatic Imaging Telescope (KAIT)
of an apparent supernova in UGC 9758 (= MCG +02-39-007). SN 1999dg
was discovered on unfiltered images taken on July 23.2 UT (mag
about 16.7) and confirmed on images taken on July 24.2 (mag about
16.5).  The new object is located at R.A. = 15h11m28s.41,
Decl. = +13o29'05".7 (2000), which is 4".8 east and 5".2 north of
the nucleus of UGC 9758.  A KAIT image of  the same field on July
15.2 (limiting mag about 19.0) showed nothing at the position of
SN 1999df.

SUPERNOVA 1999dh IN IC 211
Modjaz and Li also report the discovery (as above) of an apparent
supernova in IC 211.  SN 1999dh was discovered on unfiltered images
taken on July 23.5 UT (mag about 15.4) and confirmed on images
taken on July 24.5 (mag about 15.6).  The new object is located at
R.A. = 2h11m06s.07, Decl. = +3 51'06".9 (2000), which is 29".0 west
and 1".7 south of the nucleus of IC 211. A KAIT image of the same
field on Feb. 4.2 (limiting mag about 19.0) showed nothing at the
position of SN 1999dh.
