        Hi Alan,

        I can confirm this comet!
        It's unknown SOHO and it's a real Kreutz group comet
        found in STEREO SECCHI HI1A.
        Further confirmation will come from the
        20080217_000901 image.

            please let me also offer my congratulations to Alan! It really took some time, but
            finally...

            Let's hope for some more.

            Any reason why it was not seen with SOHO?

              Hi All, Possible, that it was typical Kreutz comet visible ONLY on C2 images (like as comets visible from april-june and october-december). What do you think?

                  Gidday All,
                  Thanks for the congrats.
                  This Kreutz is leaving HI1a at a pixel values of about 30, by my
                  processing. Values above 50 are detectable in C3. The recent bright
                  comet from John Sachs is detected at these levels.
                  I have seen previous Kreutz in HI1a that make it to C2 from these
                  levels, an early one Tony Hoffman called in C2 not seen in C3 due to
                  the noise bar being in the way.
                  I think this comet has interacted with the remnants of the CME and
                  perhaps perished early. The recent Kretuz do not seem to be able to
                  sustain a good presence in C3 and C2. See the recent attached file.

                  Oh and thanks to Rainer for the confirm, and Michal who confirmed it
                  in these secchi images also.

                    OK Alan, here's the deal -- if you can give me at least one position
                    of the object in HI1A data from Feb 17 then I'll _consider_ it. If
                    not, well I'm not sure what we'll do...

                    OK, I'm just teasing! :) It's obvisouly a real comet, it's certainly
                    not been reported in LASCO, and there are enough images on Feb 16 to
                    convince me. So it's with a great deal of pleasure that I can
                    officially confirm the following:
                    Object Name: SECCHI-1
                    Discoverer: Alan Watson

                    Many, many congratulations Alan! I know how hard you've worked for
                    this one, so you certainly deserve the discovery. Fantastic!

                    Of course, I have to add the standard disclaimer that the object will
                    need to be published by Brian Marsden before becoming "officially
                    official". I'll get it measured as soon as I can. (This week is a
                    bad week for me but I'll try and make the time.)

                      Object Name: SECCHI-1
                      Discoverer: Alan Watson

                      Many, many congratulations Alan! I know how hard you've worked for
                      this one, so you certainly deserve the discovery. Fantastic!

                      Of course, I have to add the standard disclaimer that the object will
                      need to be published by Brian Marsden before becoming "officially
                      official". I'll get it measured as soon as I can. (This week is a
                      bad week for me but I'll try and make the time.)

                      Cheers,
                      ~~Karl

                      Gidday Karl, OK Alan, here s the deal -- if you can give me at least one position of the object in HI1A data from Feb 17 then I ll _consider_ it. If not, well

                        Thanks, for the confirm Karl.  I would be very interested to find it in C3?

                            PS.
                            Karl. Maybe you should change name "SOHO Comets" website to "SOHO &
                            SECCHI Comets" ;)
