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.
