12 or more dim lights in a perfect chevron or boomerang shape

I was observing the night sky for only a few moments, when I noticed motion in my peripheral, to the north and about 80 degrees up from my location in my back yard. It was 12 or more very faint points of light forming a perfect chevron or boomerang. I watched the shape move in a linear constant speed from East to West with no sound. At first I thought it could be birds migrating, given its apparent size and silence from my perspective. But its shape was perfect and its path was perfectly straight. I could detect a shape that was greater than just the points of light as it passed over the stars, again like that of a boomerang or plane wings with no fuselage.
From my perspective, if the form were a known aircraft, it would be most similar to a B2 Bomber. However, if it were a conventional aircraft, it would have been no more than 1000 ft above the ground. Which would have produced immense sound.
Lastly, the appearance of the shape was mildly streaking or fluid in its motion. Almost like it was passing just below the surface of water.
I observed it for 10-15 seconds, starting at approximately due north of my location, until I lost sight of it over the West horizon.
