Optical and X-ray pulsations from Hercules X-1 were observed during the 1977 July/August high state of the source. Some of the optical pulastions apparently originated near the line of sight from the neutron star to the Earth. The X-ray pulse timing observations were sufficiently accurate and adjacent in time to the optical observations that a direct comparison of the optical and X-ray pulse arrival times is possible. If these optical pulsations originate within approx.10/sup 9/ cm of the neutron star, then they are emitted in phase with the X-ray pulsations, to within th measurement errors. However, it seems more likely that the optical pulsations originate in a region of enhanced density near the interaction of the accretion disk with an accretion stream from the companion star, HZ Herculis; this region should have been approximately along the line of sight from the neutron star to the Earth at the time of the observations. We use the X-ray timing data to refine the measured spin-up rate of the neutron star and the orbital parameters of the binary system.
