    Gidday,
    Backtracking of HI1A 20071101-20, I have a small object moving south across the Milky way.
    Please see attached chart and positions. I check Rainer's list but don't see a HI1A or HI2A report for around this time?

      this is impossible to say. The orbit of this comet is so badly determined, so many
      revolutions "away" and affected by many close approaches to Jupiter that its
      current orbit can be almost everyone that is possible.

      Of course it makes more sense to backward integrate P/2003 T12. I may have a look
      at it as time allows - have to get the kids to school and go to work. ;)

      Cheers, Maik
