Star Window
Once every hour*, a star moves from left to right across the star window at
6 o’clock. The star takes about four seconds to complete its trip across the
window. Once every six hours*, the star moves across the window at a faster
speed, taking only about two seconds to complete the trip.
* The timing of star movement is based on when you press A to start it.
Example: When A is pressed at 0:25 to start star movement
The star will move across the window at normal speed at 1:25, 2:25, etc. It will
move at high speed at 6:25, 12:25, etc.
You can disable star movement, if you like. 
Certain conditions can cause misalignment of the stationary position of the star, 
making it visible in the window when it is not moving. In this case, you can adjust
the stationary position of the star so it is not visible.
