We report Hubble Space Telescope imaging obtained 155 days and 449 days after the 2006 outburst of RS Ophiuchi .
Both epochs show evidence of extended emission , consistent with that seen in earlier radio observations , and a maximum expansion rate of 3200 \pm 300 km s ^ { -1 } ( in the plane of the sky ) .
The extended structure is consistent with the remnant having a bipolar morphology with an inclination similar to that determined for the binary .
