Circumpolar Year Lecture: Sounds of the Aurora and Other Persistent MysteriesNovember 8, 2011 at 7:30–9 p.m.

Dirk Lummerzheim, Research Professor Emeritus, Geophysical Institute at the University of Alaska, will present Sounds of the Aurora and Other Persistent Mysteries.

This presentation will give an overview of what aurora is, how the aurora works, where and when it can be seen, and how we came to this understanding. There are, however, a number of unexplained phenomena in
the aurora. Foremost is the question of whether the aurora produces any sound, and what it is that people report hearing during intense aurora. Although nobody can answer these questions, we can speculate about the possible explanations.
