Aurora Borealis in the Fens

Less than a month after seeing the Aurora Borealis for the first time during a holiday in Iceland, we saw them from our own back garden in the Fens. This time the lights were more of a blurry glow without any defining shapes, but they were quite bright at times, with a strong red hue easily visible to the naked eye. As best I can tell, the Kp-index was about 7 or 8 out of 9.

The photos were taken by shooting manually, with the following settings:

• ISO 3200
• Aperture f/3.5
• Exposure 4 seconds
• Manually adjusted focus so that the lights in the distance were clear
