Using recent astrometry from iTelescope Siding Spring (obtained by myself and Martin Mobberley) the orbit is starting to settle down a bit although it is still very uncertain. The 1 sigma position errors at closest approach in mid February are still around 10 degrees. I don’t think this comet will be particularly bright.
