      Dear colleagues,

      I observed 9 comets visually on Nov. 24 in Kita-karuizawa, Gunma,
      Japan.

      http://www.aerith.net/obs/diary.html

      Clear sky with almost no clouds continued all through the night. There
      was bright Moon in the evening. But the sky condition was excellent in
      the morning.

      I enjoyed the rendezvous of dwarf planet Ceres with open cluster M35.

      I also tried to observe C/2010 S1 ( LINEAR ). I found three faint
      stars of 14.0-14.5 mag around the position. But I could not find the
      comet, maybe because it located very near by these stars.

      * Comments:

      C/2009 P1 : I could see this comet again after almost 1-year
      blank. The comet became faint and diffuse, but it is
      visible visually still now.

      C/2011 UF305 : It looks diffuse as before. It became faint, but it is
      visible visually still now.

      C/2012 A2 : I could see only a very faint something near limit. Some
      observers reported it as a large bright comet of 10-11
      mag. However, I could not find such a large diffuse comet.

      C/2012 F6 : Unexpectedly, well condensed and easy to see.

      C/2012 J1 : Not visible due to the strong moon light.

      C/2012 K5 : Amazing! I was surprised that the comet got much brighter
      than expected. Strongly condensed and easy to see.

      168P : Bright Moon located very near, but the comet was visible. It
      really became a bright comet.

      260P : It keeps bright still now. I could see it well even with bright
      Moon in the evening.

      262P : Not visible due to the strong moon light.
