I don’t know what this is, but my first move would not be to call 911. Not sure what a terrestrial phone operator is going to do for you (unless that was all part of the alien plan…) Stephen Stirling writes in the Star-Ledger:
Police said they were swamped with phone calls after a flurry of callers reported to radio station NJ 101.5 that a UFO was flying above the area. Residents then began calling the Somerville Police Department to report the object.
“I first noticed when all our mechanics started looking up at the sky,” said Terry Weil, a sales associate at Honda Autosport in Bridgewater. “It looked like a big black strip fluttering in the air. Maybe a cylinder.”
Somerville Police Lt. Donna Young said authorities were not sure what the object was, but said it caused no problems other than tying up police phone lines shortly before noon.
