SUPERNOVA 2001cx IN UGC 12266
C. Yu, M. Modjaz, and W. D. Li, University of California at
Berkeley, report the discovery by LOTOSS of an apparent supernova
(mag about 18.1) in an unfiltered image taken with the Katzman
Automatic Imaging Telescope (KAIT) on June 25.5 UT (confirmed on
an earlier image taken on June 9.5 at mag about 17.9 under partly
cloudy conditions).  The new object is located at:
R.A. = 22h58m00s.28, Decl. = +6 03'48".4 (2000.0), 2".9 west and
23".3 south of the nucleus of UGC 12266.

SUPERNOVA 2001cy IN UGC 11927
M. Ganeshalingam, M. Modjaz, and W. D. Li, University of
California at Berkeley, report the discovery by LOTOSS of an
apparent supernova in unfiltered images taken with the Katzman
Automatic Imaging Telescope (KAIT) on June 30.5 (mag about 16.3)
and July 1.4 UT (mag about 16.2).  The new object is located
at R.A. = 22h09m27s.76, Decl. = +40o59'16".5 (equinox 2000.0),
which is 3".6 east and 6".1 south of the nucleus of UGC 11927.

CCD images taken on July 4.64 and 5.61 UT with a 0.30-m reflector.
SN 2001cz is located at R.A. = 12h47m30s.17, Decl. = -39o34'48".1
(2000), which is 0".6 west and 31".4 south of the nucleus of
NGC 4679.

SUPERNOVA 2001da IN NGC 7780
C. Yu and W. D. Li, University of California at Berkeley, report
the discovery by LOTOSS of an apparent supernova in unfiltered
images taken with the Katzman Automatic Imaging Telescope (KAIT)
on July 9.5 (mag about 16.5) and 10.5 UT (mag about 16.3).
SN 2001da is located at R.A. = 23h53m32s.78, Decl. = +8 07'02".6
(2000), which is 8".7 east and 2".7 south of the nucleus of
NGC 7780.

SUPERNOVA 2001db IN NGC 3256
R. Maiolino and M. Della Valle, Osservatorio Astrofisico di
Arcetri, Florence; L. Vanzi, European Southern Observatory (ESO);
and F. Mannucci, Consiglio Nazionale delle Ricerce, Florence,
report the discovery of a supernova during a campaign of near-
infrared monitoring of luminous infrared galaxies:  "SN 2001db was
discovered at mag 16.27 in a K_s-band image obtained on 2001 Jan.
9.3 UT with the ESO New Technology Telescope (+ SOFI), when
compared with a previous archival K_s image from Nov. 1999.  To our
knowledge, this is the first supernova ever discovered in the
infrared.  SN 2001db is located at R.A. = 10h27m50s.4, Decl. =
-43o54'21" (2000), which is 6" west and 6" south of the K_s
nucleus of NGC 3256 (uncertainty on relative position about
0".4).
