UFO Sighting in Bristol, New Hampshire on September 11th 2010 – light in sky would dim and blink off then blink on and get brighter repeatedlyou

I WAS OUT ON FRONT PORCH (FORGET WHY) LOOKED TO MY RIGHT NOTICING A LIGHT IN THE SKY WHICH WAS BRIGHTER THAN A STAR. I LOOKED AT IT WONDERING WHAT IT WAS. I THOUGHT IT WAS A PLANE GOING AWAY FORM ME, BUT WHEN IT BLINKED OFF THEN ON AGAIN I KNEW IT WAS NOT A PLANE. IT WAS JUST A LIGHT FROM MY POINT OF VIEW.IT DID NOT MOVE, IT JUST DIMMED OFF AND ON. AM I REALLY SEEING A UFO ? I STOOD AND WATCHED FOR A SHORT TIME. I DID NOT THINK OF MY CAMERA. AFTER I WAS KIND OF SHOCKED TO HAVE SEEN THIS. I LOST SIGHT OF IT BECAUSE I GAVE UP WATHING IT. HAVE NOT SEEN IT SINCH EVEN THOUGH I HAD HOPED TO SEE IT THE NEXT NIGHT.
