Colorful Corona (Explored) - a photo on Flickriver

Thanks Explore (#94). Position (#134)

The original northern lights film image taken in the late 1990's (www.flickr.com/photos/79387036@N07/30171286613) is considerably enhanced in this post-processed revision to bring out the colors by increasing contrast. The original image is from a negative (Etkapress with iso=640) that was scanned at 7200 dpi without modification.

Green aurora is common at high latitudes (Fairbanks, Alaska is 64N). So when other colors appeared, I often took a roll of exposures in a matter of minutes. In the age of film, the spectrum of color was not always captured or developed accurately. In this revision which occurred at the ending of twilight, I managed to record the top of the aurora lit by the last rays of the sun. That blue-purple is this resulting phenomena. Very occasionally, you can see yellow and pink in an Auroral display which are associated with only high solar activity as they are simply a mixture of red with green or blue.
