SUPERNOVA 2001ex IN UGC 3595 (Q2001/263)
On the morning of 2001 October 16, Tom Boles advised us that he was
investigating a possible supernova in UGC 3595 on multiple frames
but of a single night. Astrometry was obtained on this and follow-
up images as follows:

Oct 16.19481UT RA 06h 55m 59.85s DEC +55 24' 02.90" (2000) mag 17.2
    17.09559UT RA 06h 55m 59.93s DEC +55 24' 03.10" (2000) mag 17.1

The following IAUC appeared:
  
Guy M. Hurst, Basingstoke, England, reports the discovery of an
apparent supernova (mag 17.2) by Tom Boles, Coddenham, England, on
a 60-s unfiltered CCD frame (limiting mag 18.5) taken with a 0.36-m
telescope on Oct. 16.195 UT in the course of the U.K.Nova/Supernova
Patrol.  Boles obtained a confirming image on Oct.17.096, which
shows SN 2001ex at mag 17.1.  The new object is located at R.A. =
6h55m59s.89, Decl. = +55o24'03".0 (equinox 2000.0; average from
measures of the two images), which is 5" west of the nucleus of its
host galaxy.  A frame taken by Boles on Sept. 16.075 shows nothing
at this position (limiting mag 18.5).  Palomar Schmidt blue and red
images from 1993 and 1989 also show nothing at this location.
IAUC 7735

Subsequently spectral confirmation was obtained almost immediately
by T.Matheson:

SUPERNOVA 2001ex IN UGC 3595
Matheson et al. Harvard-Smithsonian Center for Astrohpysics, report
that a spectrum of SN 2001ex, obtained by M. Calkins as above on
Oct. 18.50 UT, shows it to be a type-Ia supernova near maximum
light.  Adopting the NED recession velocity of 7908 km/s for the
host galaxy, the supernova expansion velocity is about 9800 km/s
for Si II (rest 635.5 nm).
IAUC 7736

Our congratulations again to Tom Boles for this addition to his
discovery list: editor.

SUPERNOVA 2001ey IN MCG -1-57-10
T. Puckett and M. Marcus, Mountain Town, GA, report the discovery
of an apparent supernova (mag 17.6) on an unfiltered CCD frame
(limiting mag 19.0) taken with the Puckett Observatory 0.35-m
automated patrol telescope on Oct. 16.17 UT.  SN 2001ey is located
at R.A. = 22h26m30s.77, Decl. = -6 23'28".6 (equinox 2000.0), which
is 5".7 east and 10".4 north of the center of MCG -1-57-10.  The
new object was confirmed on CCD frames taken on Oct. 17.14.  SN
2001ey is not present on images taken by Puckett on 1999 Aug. 8 and
18 (limiting mag about 20.0) or on Palomar Sky Survey images taken  
on 1987 Sept. 15 (limiting mag about 21.0) and 1983 July 16
(limiting mag about 19.7).
