- The magnetic storm that lit up the night sky gave millions around the world quite a show. Some saw greens and purples while others saw pinks and reds. So how are the Northern Lights' different colors created? Good Question. Here's Jeff Wagner.

Always thought these were more prevalent in the winter months too.
Nope. Just longer nights, so there's more opportunities to see them.
It’s strange how blue is the rarest color while nitrogen is the most abundant gas in the atmosphere 🤔
The northern lights happen in the thermosphere. The upper thermosphere contains more oxygen than nitrogen.
So if the storm isn't strong enough, the charged particles don't reach the lower thermosphere, where there is more nitrogen.
I would say don't be surprised if we see them more often for at least the next year. The sun has an approximately 11 year cycle. The middle few years of that cycle is called solar maximum, when the sun has more flares. We're in solar maximum until at least 2025, potentially into 2026.
Wreaks havoc with radio signals too, used to be a Ham Op.

@laurabartoletti6412 Right on!, and as far as the northern lights it was Kristian Birkeland who first discovered the Sun Earth northern light connection in 1903 see the book "Northern Lights" about Kristian Birkeland by Lucy Jago!
You folks in Minnesota are pretty liberal, I'm sure you will support his handlers. I personally do not want another 4 years of what we have had. Open borders, poor economy, high crime, unaffordable housing, & inflation.

Everyone repent and prepare and follow up the FATIMA order by HOLY MOTHER MARY in 1917 pray for peace and clear the way to welcome HOLY LORD JESUS coming back
