FOR THE 5TH STRAIGHT DAY, ARCTIC AURORAS: Arctic skies aren't blue anymore. They're blue-green. With the fading of the summer sun, auroras are showing themselves in the midnight sky. Eva Kristiansen photographed these last night in Tromsø, Norway:

We've had some potential activity in the northern hemisphere for a few days but i'm pretty sure it's where our sun spots were the other week. You can see the the danger areas even if small though.

Will be interesting to see how it pans out

Note how the difference is dropping due to the variable distance from the sun.

FALL COLOURS IN THE ARCTIC: It's still summer in Scandinavia. Nevertheless... "Last night, I saw Fall colours," reports Rayann Elzein of Utsjoki, Finland. "The sky filled with green and purple during a two hour display of aurora borealis."
