Dozens of people were stopped in the middle of the sidewalks of the Chelsea neighborhood on Manhattan's West Side, looking up in the sky.
One speculated it was a balloon, another joked that it was Superman or Superwoman, and yet another wondered whether whatever it was was simply "looking for the mother ship!"
The city says its 311 help line got dozens of calls about the object.
And city officials haven't provided any answers about what it might have been - though they're said to be leaning toward the balloon camp.
