        Your probably aware that Michael Mattiazzo picked up P/2008 X4 in
        SOHO images on the 21st (UT). the comet is easily visible on images
        from 22-12-2008 and 23-12-2008 where it disappears behind the
        occulting disk between 01:42 and 06:18 UT.
        http://sohodata.nascom.nasa.gov/cgi-bin/data_query

        As of writing the comet has not exited from behind the disk. I have a
        small animation here
        http://home.mira.net/~reynella1/astronomy/20081222_registered_c3.avi (0.5 Mb)

        It is also visible on this 7mb animation

          Hi All,

          I have created a short video clip that shows P/2003 K2 = P/2008 X4
          (Christensen)
          as well as the bright Kreutz comet in C3 approaching each other and the
          sun
          in C3. This sequence has higher dynamic range making the two comets
          much
          easier to see (as well as hundreds of stars). I will try to post it to
          the StereoHunter group if there is room. The file is 2 megabytes.

            It's a beautiful sight, and it's rare to see so nicely developed a comet in SOHO--it almost looks like a telescopic view of a night-sky comet--if it weren't for the blue and orange backgrounds.

            Happy Holidays,

              Gidday All,
              This comet looks so spectacular in SOHO C2, I have used imagej to
              register and scale up the C2 images around the nucleus. Highly
              interpolated, lots of fun.

              All the best of the season to All.

              Kind regards, Alan.
