Do the Northern Lights or Aurora Make a Sound?

One interesting science mystery involves the aurora borealis or Northern Lights. Some people report hearing a sound when the auroral display is visible in the sky. Scientists have not detected a sound emanating from the aurora, at least within the range of human hearing, and any sound coming directly from the aurora would be delayed, yet the reports are too frequent and credible to be discounted. Right now, the thinking is the best way to determine the mechanism for the sound is to collect more reports of experiences. So, if you have heard the aurora, take a moment to share your story.
