From last week to this week, a precise orbit determination has been performed and the
closest distance was not improved much. The current closest distance to Earth is about
130 thousand kilometers.
The figure attached tells the outbound trajectory from Earth veers off showing the swingby
characteristics.
From now on, the ion engines are operated to target the prescribed point around the Earth,
and the decreasing speed for the closest distance will be decelerated.

Fig.1: Closest distance to Earth when Hayabusa flies ballistically from the moment designated.

Fig.2: The plane is normal to the approach velocity to Earth, and the horizontal axis corresponds to a crossing line with the equatorial plane. Sun is in the left hand side. Plots show the points where Hayabusa flies through this plane.

Fig.3: Trajectories relative to Earth in inertial frame. The plane corresponds to the ecliptic plane.

Notes: Dates designated in the left figure do not indicate the return dates.
