Just after 9pm on Thursday evening, an explosion occurred at a power plant in Astoria resulting in a glowing blue sky, which some have now dubbed the Astoria Borealis. According to NYPD, the flash of blue light was a result of an apparent transformer explosion at a Con Edison substation facility.

No injuries or damage have been reported. The utility company reported the explosion caused a transmission dip in the area after the fire involving some electrical transformers. The power outage closed La Guardia airport, temporarily grounding planes.
