SUPERNOVA 2004br IN NGC 4493
     Further to IAUC 8336, J. Graham and R. J. Foley report the
LOSS discovery, on KAIT images taken on May 15.3 and 16.3 UT, of an
apparent supernova (mag about 16.3) located at R.A. = 12h31m07s.80,
Decl. = +0o36'47".6 (equinox 2000.0), which is 9".0 west and 0".6
south of the nucleus of NGC 4493.  A KAIT image taken on Apr. 29.3
showed nothing at this position (limiting mag about 19.0).


COMETS C/2003 Q7-Q9, R2-R5, S5-S9, T8, U4 (SOHO)
     Further to IAUC 8339, K. Battams reports measurements for
additional near-sun comets found on SOHO website images by M.
Boschat (C/2003 Q7, Q8, S6), J. Sachs (C/2003 Q9, R3, S7, S8),
X.-m. Zhou (C/2003 R2), R. Kracht (C/2003 R4, S9), K. Cernis
(C/2003 R5), X. Leprette (C/2003 S5), and R. Matson (C/2003 T8,
U4).  C/2003 Q8, Q9, R2, R3, S5, S6, and S7 were observed only in
C3 images, while C/2003 R4, S9, T8, and U4 were observed only in C2
images; the remaining comets were observed in both coronagraphs.
The reduced astrometry by B. G. Marsden and R. Kisala, and orbital
elements by Marsden, appear on the MPECs cited below.  C/2003 U4
belongs to the Meyer group, and C/2003 R4 and S9 belong to no known
group.  C/2003 R5 belongs to a new group that certainly includes
C/1999 R1 and probably includes C/2002 R5.  The remaining objects
are Kreutz sungrazers.
