Discussion:

The circle above is plotted at the expected 101 km diameter of Andromache. With only one chord it is not possible to determine whether John was north or south of the central line of the event. However, assuming the updated prediction was approximately correct the close to maximum expected chord of about 99 km would suggest that the chord might lie close to the central portion of the asteroid.
