SUPERNOVA 2002hz IN UGC 12044
     M. Ganeshalingam and W. Li, University of California at
Berkeley, report the LOTOSS (cf. IAUC 7906) discovery of an
apparent supernova on an unfiltered KAIT image taken on Nov. 16.2
UT (mag about 17.8).  The new object was confirmed on an earlier
image taken on Nov. 12.2 (mag about 18.4).  SN 2002hz is located at
R.A. = 22h27m49s.54, Decl. = +38o35'09".5 (equinox 2000.0), which
is 13".9 east and 2".6 south of the nucleus of UGC 12044.  A KAIT
image taken on Nov. 2.2 showed nothing at this position (limiting
mag about 19.0).

     Further to IAUC 8006, W. M. Wood-Vasey, G. Aldering, P.
Nugent, and R. Rudas report the discovery of an apparent supernova
(mag 19.2) on unfiltered NEAT images taken at Haleakala on Oct.
30.52, 30.53, and 30.54 UT.  The new object was confirmed on NEAT
images taken at Palomar on Nov. 13 (at mag 18.6) and 14 (mag 18.5).
SN 2002ia is located at R.A. = 1h45m38s.52, Decl. = +24o08'07".9
(equinox 2000.0), which is 4" west and 4" north of the center of
the apparent host galaxy.  No point source is visible at this
location in previous NEAT images taken on 2001 Nov. 11 (limiting
mag 20.0 at S/N = 5).

2002 TD_60
     P. Pravec and L. Sarounova, Ondrejov Observatory; C.
Hergenrother, Lunar and Planetary Laboratory; P. Brown and G.
Esquerdo, University of Western Ontario; G. Masi, C. Belmonte, and
F. Mallia, Campo Catino Observatory; and A. W. Harris, Space
Science Institute, La Canada, CA, communicate:  "Our lightcurve
observations of 2002 TD_60 (MPEC 2002-T33, 2002-V32) on seven
nights during Nov. 7.1-14.1 UT revealed a complex lightcurve that
shows two periods of 2.00746 and 2.8507 hr (formal errors 0.00005
and 0.0002 hr, respectively), indicating that the object is in a
non-principal axis-rotation state.  The large amplitude of the
lightcurve (2.0 mag) indicates that the body is quite elongated,
with the maximum-to-minimum axis ratio about 3.  The fast-tumbling,
elongated body cannot be held together by self-gravitation only and
must be a coherent body with non-zero tensile strength for a
plausible asteroidal bulk density of < 8 g/cm**3.  Further
observations, especially with different techniques, are very
desirable to describe the unique object."
