I was standing in the back yard of my parents house when I noticed, coming from the north a triangular set of seven lights all white in color, moving very slowly on a direct straight line due south in the general direction of New York City.

The triangular formation of lights seemed to be fixed in relation to each other as if the lights were part of one solid object that I would estimate to have been over one football field in diameter.  
The lights from this huge, dark object seemed to be "floating" no more than maybe 1000 feet above the ground.  
At no time did I hear any sound coming from this object at all and as it passed over me the seven white lights all turned to a deep red color all at once.  
I continued to follow this object with my eyes until it was lost by me still heading south.
