Aurora borealis north of Calgary photographed by John Andersen. Courtesy of John Andersen
Colours jump out at John Andersen when he points his camera skyward at night, and he sees the strong hues displayed in his aurora photos as a sign of a large, looming geomagnetic event that could soon hit Earth.
While aurora borealis are normally green and hard to spot within Calgary’s city limits, where Andersen lives and works as a geologist in the oil industry, he seeks darker rural views north of town. His photography displays pinks, purples, and yellows, indicating powerful magnetic disturbances.
