EXPLOSION OF #PINK #AURORAS: If you spend 10 years inside the Arctic Circle, you're going to see a lot of auroras. "I have been guiding aurora tours full time for the past 10 years," says Markus Varik of Tromsø, Norway. "And I thought I I had seen it all." Think again:

"We headed out early last night (Nov. 2nd) to chase the lights--and what a surprise!" he says. "These were the most intense pink auroras I have ever seen. The pink color was bright and obvious to the naked eye. My entire group was stunned."

Pink auroras are a sign of nitrogen. Most auroras are green--the color of #oxygen atoms being struck by energetic particles 100 km to 300 km above #Earth's surface. Pink appears when energetic particles from space descend lower than usual, striking nitrogen molecules at the 100 km level and below.

What happened? Just before Varik went out aurora hunting, a crack formed in Earth's magnetic field. Energetic particles rushed through the gap, penetrating deeply enough for pink.

It has mostly dull and #cloudy today with only short periods of #sunshine. Even just a few minutes ago, it was rather overcast but suddenly, a #clouds broke and #sunight filtered through the layers and there was even some blue #sky during the #sunset.

Then, when I was about to post the above image, I noticed some #pink light in the drawing room and so went and took another set of #photographs. As I've said before, every moment is different and this has much deeper #reds. Take your pick as to which you prefer.
