Residents of the New York City borough of Queens were mystified as bright blue lights lit up the night sky on Thursday.
Thursday night, a spokesman for New York City Mayor Bill de Blasio's office tweeted that "scattered power outages were reported elsewhere".
In a statement on Twitter, Con Edison said there had been "a brief electrical fire" at one of its substations in Queens, "which involved some electrical transformers and caused a transmission dip in the area".
He says the flash subsided on its own. "Many flights are departing, some are not", the airport wrote on its Twitter account, later adding that power was back in "all terminals" and advising passengers to check with airlines for flight status information. Con Edison crews responded with FDNY.
Reports soon came in that La Guardia had lost power and that the airport had closed as a result. Air traffic control facilities continued operations because they went immediately to generator power, said FAA Eastern Region spokesman Gregory Martin. All power lines serving the area are in service and the system is stable. Footage of the scene showed the sky flickering a bright blue-green for several minutes.More news: Manmohan Singh's biopic riveting: BJP; Cong wants screening before release
"We're now investigating the cause of the incident", the agency said.
The MTA also reported issues on the No. 7 train because of the outages. 'Please avoid 20th Ave & 31 st'.
Judith Enck, the former Environmental Protection Agency regional administrator for NY, told the Huffington Post that the "very old and very polluting" Astoria plant "should have been shut down quite a while ago" and replaced with clean electricity sources.
"My daughter saw these insane blue lights in sky over Queens from the train!" one user tweeted.
