After yesterday’s meeting at Burlington House Peter Carson has obtained some more astrometry of this object. I’ve added that to the collection and the output from findorb is attached. As I said at the meeting yesterday the period and perihelion date are very poorly constrained at the moment and the residuals aren’t much different if you force the orbit to be parabolic. Astrometry over the next couple of weeks should start to resolve that so we should at least have a good idea of the orbit. It will be a few years before we can even guess how bright it is likely to be when it comes to perihelion in 2023.
