C/2004 J5 was also found by Hoffman. Marsden performed the reductions for C/2004 F6, which was a bright comet showing a short tail in both C3 and C2 images. All are Kreutz comets except for the following Krachtgroup members: C/2004 J4, J12, J13, J15, and J16. C/2004 J4 and J12 were also fairly bright, fading gradually as they neared the sun.
