The "advancing screen", as represented by the gray screen, moves across the binary orbit of Star B (blue circle) and Star A (red circle) in the direction of the arrows at a speed of 15 m/s. In the top left image, both of the stars are unobscured by the circumbinary ring. In the top right image, the screen fully occults the orbit of Star B, and part of star A's orbit. This allows Star A to "rise" and "set", or appear to be "winking". The bottom left shows the screen block both orbits, which occurred in 2010 until 2012. The bottom right shows the current state of the system, the orbit of Star A is occulted while Star B "rises" and "sets", as Star A previously did.
