The Final Show


A daily six minute gain in sunlight means night time here in the far north is rapidly sinking southward as the months progress into summer. With the departure of darkness comes the fading of the northern lights. Yes, auroras happen all year-round, but they of course are not visible when the sun is out. Last night, I stayed up past civil twilight to wish the aurora a fond farewell. Earth has just received a glancing blow by a coronal mass ejection (CME) from an unstable region of the Sun, igniting what was likely the final solar storm of the 2015-16 auroral season for the Northern Hemisphere. The northern lights will soon be overwhelmed by the midnight sun, until darkness once again returns in August. Now it's the Southern Hemisphere's turn to experience the green lights.

  1. Ooooo - very nice!

    Is that the mailbox tree? I feel so well informed now that I've visited.

    Looking forward to more photos of the upcoming 'light' changes.

    xo,

    1. If we had a mailbox, I bet it would go nearby. It's the dead tree at the entrance of our driveway we nailed our house address to.
