You can filter a selection:

vis.selectAll('circle.prospect')
.on("mouseover", function(d) { 
     console.log(d);
    var circleUnderMouse = this;
    d3.selectAll('circle.prospect').filter(function(d,i) {
      return (this !== circleUnderMouse);
    }).transition().style('opacity','0.5');
    d3.select(this).attr('opacity','1.0');
  });
