Explanation: It appeared, momentarily, like a 50-km tall banded flag. In mid-March of 2015, 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. Now past Solar Minimum, colorful nights of auroras over Earth are likely to increase.

So the LGBTXYZ types can now claim that the aurora borealis has gay pride? LOL.

Oh no! Not THAT flag!!!
If I was a carnivorous space alien, I’d probably consume the swedes first too.

Photographs don't convey how BIG they are.
Gorgeous picture though.

I posted the pic of the spacecraft from Close Encounters because I thought the musical notes you posted were the ‘signal’ notes from that movie.........

Oh, sorry! Yes, those were the notes. :)
I was pinging RedwM because he claimed to have seen something like this in the sky the other night, on the other APOTD thread.

Even though I’m at work and don’t have access to a musical instrument and am practically deaf, I could ‘hear’ those notes in my mind, and suspected that was what they were..............................

Yep. Something none of us will ever forget, once heard! D@mn you, Spielberg, LOL!
‘Raiders of the Lost Ark’ theme song, too, or the ‘scary shark music’ when JAWS is about to strike!
Now THOSE tunes are in your head for the rest of the day, LOL!
