Brian Luenser witnessed something Tuesday night he had never seen before: blue, purple, orange and red fireballs lighting up the Fort Worth, Texas sky.

“€œI was really scared,” Luenser, an amateur photographer with a passion for taking pictures of lightning, told The Huffington Post. “€œThe whole sky was lighting up. I didn’t know if it was nuclear explosions or what.”

But he wasn’€™t too scared to shoot a video of the spectacle from the balcony of his 34th-floor condominium.

The explosions were the result of lightning striking “feeders,” the lines that transmit electricity to neighborhoods, according to Jeamy Molina, a spokesperson for Oncor, the electrical company that serves the area.

The storm left about 4,000 people without power, and Luenser said that the explosions lasted for about 25 minutes. Molina said that power has been restored to those who lost it on Tuesday night.

Matt Mosier, a meteorologist with the National Weather Service, told the Fort Worth Star-Telegram that there were more than 120 lightning strikes from 9:00 to 10:00 p.m. Luenser said that he captured the video between 9:30 and 10 p.m.
