Astronomy Picture of the Day -- A Flag Shaped Aurora over Sweden
NASA ^ | March 30, 2015 | (see photo credit)

Explanation: It appeared, momentarily, like a 50-km tall banded flag. In mid-March, an energetic Coronal Mass Ejection directed toward a clear magnetic channel to Earth led to one of the more intense geomagnetic storms of recent years. A visual result was wide spread auroras being seen over many countries near Earth's magnetic poles. Captured over Kiruna, Sweden, the image features an unusually straight auroral curtain with the green color emitted low in the Earth's atmosphere, and red many kilometers higher up. It is unclear where the rare purple aurora originates, but it might involve an unusual blue aurora at an even lower altitude than the green, seen superposed with a much higher red. As the Sun continues near its top level of surface activity, colorful nights of auroras over Earth are likely to continue.

Jesus says there will be “signs in the heavens” before the end of the world. (Luke 21:25-28) Always be ready to welcome Him.

For those of you who have seen an aurora, what does it really look like in real time? I have seen untold numbers of movies that were sped up and altered in other ways. Auroras can’t move as fast as what I’ve seen.

A close examination has me guessing this is a stacked image, a processed joining of more than two exposures of varying speeds. Perhaps as a result it loses some of its granularity at full size, though the phenomena is still remarkable. A wider shot might have revealed more meandering. Framed as it was would have made the curtain “in a gentle breeze” effect less unlikely.
