Three dull orange spheres flying silently in succession.I was looking up in the night sky with my binoculars at Jupiter and then the constellation of Orion when I noticed three orange spherical objects coming from the east. First I assumed that they were airliners or local aircraft, but when I saw that they were flying at the same altitude, at approximately a couple thousand feet, and in relatively close proximity to one another (maybe couple thousand feet apart) and one right behind the other, I didn't think it was airliners. when there are multiple airliners flying at one time, they are required to maintain a certain distance apart, vertically and horizontally. These craft were flying one right behind another and all at the same height. There were no navigation or strobe lights typical with any type of airplanes, nor was there any sound associated with the craft (they were absolutely silent) neither jet nor props. The craft weren't moving fast, so I was able to view them with my binoculars and I didn't see any! detail in the craft except a dull orange color. The craft, still in the same linear formation, made a relatively sharp curve to the south and rapidly faded from view. These were neither meteors, ballons, fireworks,birds, nor satellites as the craft's movements did not correspond to any type of those objects.
