      Hi Folks,

      Comet P/2008 X4 Christensen is now visible in SOHO LASCO C3 images.

      http://sohowww.nascom.nasa.gov/cgi-bin/realtime_query

      Using 1024x1024 resolution.

      Positions at 20081221
      UT
      0018 39,627
      0042 46,625
      0142 54,624
      0218 59,623
      0242 63,623
      0318 67,622
      0342 71,622

      The orbit needs slight refinement, as it is about 25' west from prediction.
      It appears to be about magnitude 9 and will pass south of M28 in a few hours
      time.

      Cheers,
      Michael Mattiazzo

      ... few hours ... Please note that LASCO lim. magnitude is about 8.0. I estimated this comet as 7th magnitude using MaxIm DL. Regards, Dimitry
