SUPERNOVA 2001ex IN UGC 3595
     G. M. Hurst, Basingstoke, England, reports the discovery of an
apparent supernova (mag 17.2) by T. 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.


SUPERNOVA 2001ey IN MCG -01-57-10
     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 -01-57-10.  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).


2001 OE_84
     P. Pravec and P. Kusnirak, Ondrejov Observatory, write:  "Our
photometric observations of this Amor-type minor planet (cf. MPEC
2001-P09, 2001-T04) on Oct. 15.1 and 16.0 UT reveal a rotation
period of 29.190 +/- 0.002 min, indicating that it is a body with
non-zero tensile strength (monolithic), the first known minor
planet of this kind in the km-size range (H = 17.7, diameter about
0.9 km).  Its lightcurve and further information are posted at
http://sunkl.asu.cas.cz/~ppravec/2001oe84.htm.  Observations with
other techniques (e.g., spectral, infrared) are desirable."
