COMETS C/2008 L9-L15 AND C/2008 M1-M7 (SOHO)
     Further to IAUC 8983, additional near-sun presumed comets have
been found on SOHO website images -- all Kreutz sungrazers except
for C/2008 L11 and C/2008 L15 (members of the Meyer group).  K.
Battams writes that C/2008 L9 (which was also found by B. Zhou) was
small and stellar in appearance (mag about 7) in C3 images, and
quite diffuse with a short, diffuse tail in C2 images.  C/2008 L10
and C/2008 L15 were stellar in appearance (mag about 7-7.5).
C/2008 L11 was stellar in appearance, reaching mag about 5.5-6 in
C2 images.  C/2008 L12 was quite diffuse (mag about 7.5-8).  C/2008
L13, C/2008 M2, and C/2008 M5 were slightly diffuse (mag about 8).
C/2008 L14 was teardrop-shaped (mag about 3-4) in C3 images, and
showed a diffuse tail about 0.25 deg long in C2 images (the tail
also similarly visible in SECCHI COR2-A images, and as somewhat
fainter and shorter in COR2-B images).  C/2008 M1 was tiny and
stellar in appearance (mag about 8).  C/2008 M3 was slightly
diffuse (mag about 7.5-8).  C/2008 M4 was extremely faint (mag
about 8.5) and very diffuse.  C/2008 M6 was very small, faint (mag
about 8), and somewhat stellar in appearance.  C/2008 M7 (which
was also found by H. Su) was very diffuse (mag about 8).
