      Gidday Michael, this looks good, confirm comet. There is a report in SOHO around 20090717, not confirmed, also not likely given timing. Attached a small GIF

        Hi Alan,
        I saw this report. Typical Kreutz comet when entering in LASCO C3 FOW (el. ~7.5 deg) should be visible in July ~30-35 hours in LASCO C3. As we see Masanori's report "do not reply" for this comet.

        Hopefully that I'm lucky :)

              Hi All,

              I also couldn't find it in COR2-B, but my sharp-eyed summer student Shannon Hicks (who's name you may have spotted on some recent MPECs) was able to find it. It actually looks quite different in COR2-B than COR2-A -- I was very surprised. Here are a few of the positions Shannon found:
              COR2-B, 1024x1024, (0,0) lower-left

              2009-07-18T22:52:49 566 303

              So we (actually, Shannon again) can confirm this comet as STEREO-21 -- congrats, Michal! She has made the measurements and we sent them off to Brian a while ago along with the remaining unmeasured SECCHI/STEREO comets (#8,#18 and #19).

              You'll see that we've very close to being up-to-date with SOHO again. I now need to update the website...

                Comet was quite right (perhaps ~6 mag). So, I think there is a chance to find that.

                        Hi Dimitry,

                        thanks for the COR2 PNGs.

                        A better orbit is

                        TP 2009 June 30.594

                        Incl. 89.52

                        From 21 observations 2009 June 29-30 (9.2 hr); RMS 12.1"

                        I don't think that this will change the path in COR2 very much.
