        this is very interesting indeed. Now there are some more observations but the
        astrometry seems very bad: The residuals are quite large and I can't receive a
        good solution. Forcing a i=144 and e=1 solution does not help. The object is at
        only 40° elongation and inbound.

        If it survives it may be detected soon on SOHO images.

        Cheers, Maik

              The angular elements nicely fit that of the Kreutz group, but the perihelion distance is too small and would be inside the Sun! Clearly more astrometry is needed.

              If this would really be a Kreutz comet (and there are outliers with i around 100 known) then it would be the first one discovered and observed from the ground since 1970!

              This is going to be an exciting weekend!

                I have excluded all observations of November 29.

                I dare to bet that this is a Kreutz comet.

                I assume that the inconsistent astrometry is due to a very diffuse morphology of the object. I hope this does not mean that it is already in a state of disintegration.

                    New orbit upadte at the NEOCP (including I39,I36 observations) shows the Kreutz solution!
                    Let's wait for additional observation, but I think that this comet may be similar to comet 1945 du Toit.
