These images were taken in my garden on the 28th February 2014 at sunset. It was reported on my local news broadcast that the Aurora Borealis maybe visible so I kept watch that evening and this is what the eye was to behold. I can not be certain that this was nothing more that a February sunset and I do not claim that is anything more that just that. But to me it is a beautiful atmospheric sky over the roof tops.
A local newpaper reported sightings of the Northern Lights in the county on the previous evening.
