Pulsating Northern Lights were captured during a sailing aboard the Trollfjord over northern Norway in a rarely witnessed event, Hurtigruten said in a press release. 

The footage was captured by the company’s Chief Aurora Chaser, Tom Kerss, on February 22, 2026, but was discovered in April when he was reviewing video content at the end of the aurora season.

According to the cruise line, the unusually powerful display of pulsating Northern Lights is one of the longest on record.

“I’ve been chasing the Northern Lights for more than 18 years, and this occurrence is one of the most profound sightings of my career and the most memorable night of aurora-chasing I’ve experienced. Even to the naked eye, it was clear something exceptional was happening, with visible pulses and shifting color,” said Kerss.

“The display lasted for hours, flashing pink and green long after midnight. Seeing it from the open deck in Arctic Norway, far from light pollution, made it even more remarkable. The footage captures not just the beauty, but rare detail that offers real scientific insight.”

Having lead Astronomy Voyages on Hurtigruten since 2023, Kerss became the world’s first Chief Aurora Chaser in 2024.

He captured the pulsating Northern Lights during a sailing near Narvik, following a strong auroral substorm.

Unlike typical pulsating auroras, which last just 10–20 minutes, this display continued for hours, the cruise line explained.

A video of the phenomenon is available on YouTube.
