Possible Close Approach of 2016 WM1

It's good that the MPC does that but the position would be only accurate for the epoch date (Jan 21). Any ephemeris that we produce using that epoch is only accurate for a short time if the software does a 2-body computation (common amateur astronomy packages). Using Horizons or software that uses gravitational perturbations of the solar system will give better positions. But until this rock is recovered, all bet are off!
