Black Triangle Sighting in Fitchburg, Massachusetts on 2013-06-08 00:00:00 - Dark triangle object with green lights on corner stationary two bottom lights almost "absorbed" by top light and then disappeared entirely

Standing on my porch one evening and looked up, saw a dark triangle shaped object with three bright lights, one at each corner, hovering over my house at quite a distance but still distinguishable. object did not move except when the two lower lights were drawn up or absorbed by the top light at a unnatural speed which then disappeared just as quickly. it has taken me years to come to terms with what i saw, i do not know what it was, but i know it's been unexplainable thusfar.
