        Nice catch! But it's pretty dim for an comet that is supposedly
        magnitude 8! No wonder I couldn't find it.

            Hi all,

            I've made an animation of Comet Lulin here: http://comethunter.lamost.org/secchi/CK07N030_HI1a.gif
            Hope u could like it! I'll try to do astrometry with Astrometrica (always led to negative star-matches whenever I was attempting to do astrometry with SECCHI images, strangely) or PIXY System 2 (once successfully!) of it probably this weekend once I'm free.

            Cheers, Wentao

                         (40) Harmonia is long this line of y values so  I suspect this is it?
