Alexandra K. Scammell

COPY joined Eos as the associate editor in 2021 after more than 5 years working at the American Association for the Advancement of Science (AAAS) as a writer and associate editor. She has a M.A. in science writing from Johns Hopkins University and a B.A. in communications from the College of Agriculture and Life Sciences at Cornell University.

Side-by-side images show fish-eye-style photographs of a starry evening sky illuminated by different subauroral events. The left image shows a SAR arc, a reddish arc that spans the sky. Beneath the arc the sky transitions from bright green at the horizon to purple and is partially obscured by clouds. The right image shows a STEVE phenomenon. Part of the red SAR arc is still visible but is much fainter and more of a pink color than its original red. The green and purple sky is more muted in color, and more stars and the band of the Milky Way are now visible. In both images, the silhouette of some shrubs is visible.
