I looked in the bright blue sky and saw a large formation of white discs.

It was a beautiful spring day and the bright blue sky was clear with no clouds with had a light breeze. I was on the corner of the location waiting for a friend when I looked up in the sky and saw a formation of at least 12 white objects hovering in a pattern. I immediately thought it might be drones, but they were white and in a formation which I believe would be difficult for someone to navigate. Additionally, flying drones in NYC is illegal- though people do fly solo drones in certain places. The objects were hovering above the surrounding apartment buildings, but lower than any airplanes. The formation would shift but stay in a group. It was the strangest thing I've seen, so I stopped a couple of guys walking by and asked them what they thought it was? First, they also thought it could be drones but agreed it was different and unlike anything they've seen either. The objects hovered in the pattern for another few minutes then moved west out of my site range.
