Aurora borealis confirmed to be making 'strange sounds' (and perhaps getting LOUDER)!

Northern lights sound like a kind of clapping, or applause, just 230 feet above the ground. The study confirms reports
by wilderness travelers who say they've heard strange noises when the northern lights appear.

According to the Geophysical Institute of the University of Alaska-Fairbanks, the aurora borealis is a luminous glow of
the upper atmosphere which is caused by energetic particles that enter the atmosphere from above. The energetic
particles that make the aurora borealis come from the magnetosphere.

While FMI was taking measurements of geomagnetic disturbances, researchers used three microphones to capture
up to 8 hours of recordings. Analyzing these recordings in relation to the FMI measurements, researchers were able to
determine that the sounds formed about 70 meters above the ground level in the measured case.

“Our research proved that, during the occurrence of the northern lights, people can hear natural auroral sounds
related to what they see,” said Aalto University Professor Unto K. Laine. “In the past, researchers thought that the
aurora borealis was too far away for people to hear the sounds it made. This is true. However, our research proves
that the source of the sounds that are associated with the aurora borealis we see is likely caused by the same
energetic particles from the sun that create the northern lights far away in the sky. These particles or the
geomagnetic disturbance produced by them seem to create sound much closer to the ground.”
