COMETS C/2006 S12, C/2006 S13, C/2006 T2-T9 (SOHO)
Additional apparent comets have been found on SOHO website
images (cf. IAUC 8774), all being Kreutz sungrazers except C/2006
T6 (Meyer group). K. Battams notes that C/2006 S12 was small,
stellar in appearance, and around mag 6 in C3 coronagraph images,
while it appeared slightly diffuse with no tail in C2 images.
C/2006 S13 was very small and around mag 7 in C3 frames, and it
appeared small, quite diffuse, and extremely faint in C2 exposures.
C/2006 T2 was small, stellar in appearance, and around mag 6 in C3
images, and quite diffuse and faint in C2 frames. C/2006 T3 was
tiny, stellar in appearance, and of mag about 7.5 in C3 exposures,
but it appeared very diffuse and faint in C2 images. C/2006 T4
(which was also found by T. Chen) was diffuse and extremely faint
(mag 7.5-8.0) in C3 images, and extremely diffuse and faint in C2
frames. C/2006 T5 was slightly diffuse, extremely small, and faint
(mag about 8). C/2006 T6 was tiny and stellar in appearance in all
exposures, being very faint (mag 7.5-8) in C3 frames and fading
rapidly in C2 images. C/2006 T7 and C/2006 T9 were extremely faint
(mag about 8.5) and diffuse with no tail. C/2006 T8 was tiny,
stellar in appearance, and of mag about 7.5 in C3 images, while C2
frames showed it to be faint and diffuse with a hint of tail.
