From a Galaxy.  The Circulate path of a
  Galaxy consists of 8 spots.  Move up to the next position in the Galaxy (Box
  dancers move forward into the next outside Diamond position,
  as Diamond dancers move forward into the next Center position).  Your new
  facing direction is determined by the dancer currently occupying the spot to
  which you will move.  You must either face the same direction as that dancer
  (i.e., you are following his or her back), or 180° in the opposite
  direction (facing Galaxy Circulate).  This means that sometimes your facing
  direction will change 90° and sometimes your facing direction will not
  change at all.  From a normal R-H or L-H Galaxy, the traffic pattern of 
Galaxy Circulate
  results in all dancers moving in either a clockwise or
  
counter-clockwise direction, respectively.  If no dancers come to the same
  spot, then 
Galaxy Circulate ends in a Galaxy.
