SUPERNOVA 2003ma
     A. Rest, Physics Department, Harvard University, on behalf of
the SuperMACHO collaboration, reports the discovery of a supernova
(at "VR" magnitude 20.5) at z = 0.289 behind the Large Magellanic
Cloud on images obtained on 2003 Dec. 13 with the Cerro Tololo 4-m
Blanco telescope in the course of the SuperMACHO microlensing
survey (Rest et al. 2005, Ap.J. 634, 1103).  The object, designated
SN 2003ma, faded by only 2.9 mag in I over the first 4.7 years
following peak brightness (I = 19.7).  It is located at R.A. =
5h31m01s.878, Decl. = -70o04'15".89 (equinox 2000.0), which is 0".1
south of its host galaxy.  Spectroscopy obtained with the Gemini
South telescope (+ GMOS) on 2003 Dec. 22.3 and with the Magellan Clay
telescope (+ MagE) on 2008 Dec. 28.3 shows 2003ma to be a very
luminous type-IIn supernova, similar to SN 1988Z (Turatto et al.
1993, MNRAS 262, 128).  The 2008 spectrum shows an intermediate-
width H_alpha line with a FWHM of 5800 km/s.  Details will be
given in a paper by Rest et al. (2009, Ap.J., submitted).


COMET P/2009 U6 (LINEAR)
     K. Kadota, Ageo, Saitama-ken, Japan, reports pre-discovery CCD
images of this comet (cf. IAUC 9090), obtained with a 0.25-m f/5
reflector on Oct. 19.80-19.81 UT, showing the object at total mag
16.8 with a 0'.4 coma and a tail 0'.7 long in p.a. 285 deg.  The
following elliptical orbital elements (from 29 observations, Oct.
19-30) appear on MPC 67414:

     T = 2009 Aug. 11.839 TT          Peri. = 311.110
     e = 0.59878                      Node  = 112.915   2000.0
     q = 1.51357 AU                   Incl. =  14.680
       a =  3.77239 AU     n = 0.134518     P =   7.33 years


COMETS C/2009 K13 AND C/2009 K14 (SOHO)
     Further to IAUC 9091, additional Kreutz sungrazers have been
found on SOHO website images.  C/2009 K13 was slightly diffuse and
small (mag about 8).  C/2009 K14 was very diffuse and very faint
(mag about 8-8.5).
