S. Noll, Space Telescope Science Institute (STSI) et. al., report on IAUC 9046 that images taken during 2008 Nov. 8.9381-8.9700 UT with the Wide Field Planetary Camera 2 on the Hubble Space Telescope reveal a binary companion to 2002 XH_91. The two components, detected in each of four exposures made through the F606W (wide-V) filter, were separated by 0".582 +/- 0".009. The secondary, fainter by 1.04 magnitude, was located at 0".538 +/- 0".004 in R.A. and 0".222 +/- 0".008 in Decl. relative to the primary.
