He I ﹩\lambda 6678﹩ profiles obtained near ﹩\Psi =0﹩ and ﹩\phi =0﹩, plotted in a format similar to Fig. 6. The tick marks indicate the positions of a central absorption feature that moved redward in this sequence in the manner expected for the optical star. The absorption feature disappeared on the subsequent 3 nights when the optical star was behind the disk.
