COMETS C/2007 J8-J12 AND C/2007 K7-K18 (SOHO)
     Additional near-sun comets (cf. IAUC 8853) have been found on
SOHO website images -- all being Kreutz sungrazers except for
C/2007 K12 (Meyer group).  K. Battams reports that C/2007 J8, K7,
K9, and K11 were slightly diffuse and very faint (mag 8) with no
tail.  C/2007 J9 was stellar (mag about 6.5) in C3 images, and very
slightly diffuse with a hint of tail in C2 images.  C/2007 J10, K13,
K15, and K16 were slightly diffuse and faint (mag about 7.5).
C/2007 J11 was stellar in C3 images, and was of mag about 6.5 with
a hint of tail in C2 images.  C/2007 J12 was extremely faint in C3
images and "very faint/diffuse" (mag 8) in C2 images.  C/2007 K8
was stellar in appearance in C3 images, and slightly diffuse (mag
about 7) with a hint of tail in C2 images.  C/2007 K10 was stellar
in appearance and faint in C3 images, and slightly diffuse and
elongated (mag about 7.5) in C2 images.  C/2007 K12 was stellar in
appearance, elongated (but not in the direction of motion), and of
mag about 6.5.  C/2007 K14 was extremely faint (mag about 8.5) and
fairly diffuse.  C/2007 K17 was very faint (mag about 8), elongated,
and diffuse.  C/2007 K18 was faint and stellar in appearance in C3
images, and slightly diffuse (mag about 7) with a hint of tail in
C2 images.
