Photographing Payson Aurora on April 18, 2002

with the new All Sky Camera

Updated 4/18/02

Photographic Aurora are the most difficult yet most common type to phogaph. In Arizona, we have less than one visible display per year of the Aurora during solar maximum. But the photographic Aurora are 10 times more common, if you know when and how to shoot them. On April 17/18 the Kp value rose to a moderate 6.5 for a few hours, normally too low to see an active display. But we shoot the northern horizon even if we dont see anything, and most of the time we get rewarded with nothing. This time, it was a sucess story, the last few frames of the night had the telltale red glow in the north showing a auroral storm in progress deep to the north. The new All Sky Camera was put into play for this exact patrol work several months ago, and we hit paydirt last night! Because the Aurora are almost always red here in Arizona, Kodak E200 was used to capture its elusive glow. A 50mm f/2.8 camera lens was used to photograph the convex surface and obtain the 180 degree sky coverage.
