About the cover

Weather observer Nick Roden took this photograph of the aurora australis, intersected by the LIDAR laser beam at Davis station, on a cold July night this year. The aurora australis results from the interaction of the solar wind with the Earth’s magnetic field. ‘Excited’ oxygen atoms hit by charged particles from the sun emit river-like ribbons of neon-green light as they return to their lowest energy state. Nick says it took only 30 seconds to take the photograph but planning for it and waiting for the right conditions took many months. Another of Nick’s aurora photos features in this issue’s Freeze Frame section on page 37.
