The lander trajectory is being significantly affected by the propellant leak. My astrometry of it tonight (Jan 10) is around 2 arcmins from where it should be assuming a ballistic trajectory. The spacecraft is around mag 18 tonight. The Centaur is much better behaved and quite bright (mag 14). We should be able to follow that for quite some time as it goes off in a heliocentric orbit. I’ve attached an ephemeris for the Centaur in case you want to have a go.
