A transformer fire in Queens sent an eerie blue light which flooded the nighttime sky over New York City on Thursday night as electricity flickered in homes and LaGuardia Airport was plunged into darkness, NBC News reports.

Con Edison said a brief electrical fire involving transformers broke out at the substation on 20th Avenue and 32nd Street in Astoria, causing a transmission dip in the area.

The fire lit the sky so brightly that it briefly appeared to be daytime in neighborhoods like Astoria and Woodside. Smoke arose from the source of the blue light, which was visible from as far as Manhattan.

Con Edison said it was investigating the cause of the transformer fire. There were no injuries.
