COMETS C/2009 L3-L17, C/2009 M1, AND C/2009 M2 (SOHO)
     Further to IAUC 9059, additional presumed comets have been
found on SOHO website images, all being Kreutz sungrazers except
for C/2009 L8 and C/2009 L13 (Kracht group).  C/2009 L3 was very
diffuse and slightly elongated (mag about 7.5).  C/2009 L4 was
stellar in appearance (mag about 6.5) in C3 images but quite large
and very condensed with no visible tail in C2 images; COR2-A STEREO
images show a bright starlike head and a very faint, thin tail.
C/2009 L5, C/2009 L7, C/2009 L11 (also described as small), and
C/2009 L15 were slightly diffuse (peak magnitudes about 7.5, 7.5-8,
8, and 8, respectively).  C/2009 L6 was stellar in appearance (mag
about 6.5-7) in C3 images, and condensed with no tail in C2 images.
C/2009 L8 (mag about 7-7.5) and C/2009 L13 (mag about 7.5-8) were
small and stellar in appearance.  C/2009 L9 and C/2009 L12 were
very diffuse (mag about 8).  C/2009 L10 (slightly diffuse), C/2009
L14 (quite diffuse), and C/2009 M1 (quite diffuse) were very faint
(mag about 8.5).  C/2009 L16 was quite diffuse (mag about 7.5).
C/2009 L17 was stellar in appearance (mag about 6.5) in C3 images,
but quite diffuse with a short, faint tail in C2 images.  C/2009
M2 was small and stellar in appearance (mag about 7) in C3 images,
and showed a hint of a very faint tail in C2 images.
