    Fig. 1Hubble Space Telescope image showing the close passage of the nearby white dwarf Stein 2051 B in front of a distant source star.

    This color image was made by combining the F814W (orange) and F606W (blue) frames, obtained at epoch E1. The path of Stein 2051 B across the field due to its proper motion toward southeast, combined with its parallax due to the motion of Earth around the Sun, is shown by the wavy cyan line. The small blue squares mark the position of Stein 2051 B at each of our eight observing epochs, E1 through E8. Its proper motion in 1 year is shown by an arrow. Labels give the observation date at each epoch. The source is also labeled; the motion of the source is too small to be visible on this scale. Linear features are diffraction spikes from Stein 2051 B and the red dwarf star Stein 2051 A, which falls outside the lower right of the image. Stein 2051 B passed 0.103 arcsec from the source star on 5 March 2014. Individual images taken at all the eight epochs, and an animated video showing the images at all epochs are shown in fig. S1 and movie S1 (24).
