SUPERNOVA 2001dp IN NGC 3953
     M. Migliardi and E. Dal Farra, Tourtour, Haute-Provence,
France, report their discovery of an apparent supernova (mag 14.5)
on CCD images obtained on Aug. 12.9 (limiting mag about 17) and
13.9 UT with a 0.2-m Schmidt-Cassegrain telescope in the course of
the CROSS program (cf. IAUC 7373).  The new object is located at
R.A. = 11h53m45s.1, Decl. = +52o20'57" (equinox 2000.0), which is
24" west and 81" north of the nucleus of NGC 3953.  A CROSS image
taken on Apr. 13 showed nothing at this position (limiting mag
about 18.5), and it does not appear on Palomar Sky Survey images.
Migliardi adds that another image obtained on Aug. 14.83 shows SN
2001dp at mag 14.4.  T. Kato, Kyoto University, forwards the
following position end figures from an unfiltered CCD image
obtained with a 0.28-m reflector by Y. Sano, Nayoro, Hokkaido,
Japan, on Aug. 15.491 (supernova at mag 14.6, from USNO-A2.0 red
comparison-star magnitudes):  45s.22, 56".8 (which is 34".8 west
and 80".2 north of the galaxy nucleus).
     K. Ayani, Bisei Astronomical Observatory (BAO), reports that
spectra (range 400-800 nm) of SN 2001dp were obtained with the BAO
1.01-m telescope on Aug. 15.5 UT by himself with T. Kawabata, M.
Ioroi, O. Ohshima, and participants of the BAO Summer School 2001.
The spectra resemble that of the type-Ia SN 1994D, one month after

SUPERNOVA 2001dq IN IC 1222
     M. Modjaz and W. D. Li, University of California at Berkeley,
report the discovery by LOTOSS (cf. IAUC 7514) of an apparent
supernova (mag about 18.8) in unfiltered images taken with the
Katzman Automatic Imaging Telescope (KAIT) on Aug. 14.2 and 15.2 UT
(limiting mag about 20.0).  SN 2001dq is also present on earlier
images taken on July 28.2, Aug. 1.2, and Aug. 9.2, all with mag
about 18.8.  The new object is located at R.A. = 16h35m10s.95, Decl.
= +46o12'50".5 (equinox 2000.0), which is 18".5 east and 0".2 north
of the nucleus of IC 1222.  KAIT images taken on 2001 July 23.2
(limiting mag about 19.0) and 1998 Sept. 13.2 (limiting mag about
19.5) showed nothing at this position.

SUPERNOVA 2001do IN UGC 11459
     M. Armstrong, Rolvenden, Kent, England, reports that he
obtained an unfiltered CCD image of SN 2001do (cf. IAUC 7682) at
mag 16.2 during his search program on Aug. 14.9 UT.  He provides
the following precise position:  R.A. = 19h37m22s.76, Decl. =
+40o42'22".8 (equinox 2000.0)
