Large pulsating triangular object seen hovering over town for at least an hour.Two mornings in a row now I have seen a large craft/ unidentified flying object hovering above Hagerstown in the north eastern sky at approximately 4-4:30am. From my vantage point it appears to be somewhere above the fairgrounds or perhaps farther out of town. I have ruled out plane due to the fact that while observing it for an hour it barely moved. Most fascinating is the spectacular light show this thing is giving off and is what first caught my attention. It pulsates with just about every color of the spectrum around the edges of the craft and the bottom portion looks as though it's erupting with fire. Last night the object was much closer and I was able to vaguely make out a shape that I can only describe as something out of battlestar galactica it appeared to be triangular, but not perfectly triangle. It's edges were rounded appearing almost like a boomer-ring! I was also able to hear a loud hum like noise emanating from the object even at a distance. I awoke my Fiance the second night to verify what i was seeing and she was just as baffled and amazed as I. When trying to capture the object on video and picture the quality was very blurred so i quickly drew a quick concept of what I seen on a small white board I keep in my kitchen while it was fresh in my mind.
