365Caws is now in its 14th year of publication, and was originally intended to end after 365 days. It has sometimes been difficult for me to find new material, particularly during the winter months, but now as I enter my own twilight years, I cannot guarantee that I will be able to provide daily posts. It is my hope that along the way I may have inspired someone to a greater curiosity about the natural world. If so, I can rest, content in the knowledge that my work here has been done.

Aurorae
Day 211: The camera registered colours my eyes could barely perceive, but even what was visually apparent was the most spectacular aurora borealis I've experienced in my entire lifetime. The entire sky was filled with curtains and streamers, east to west, north to south, green and red and white. They changed gradually, almost imperceptibly, fading from view in one minute, returning over the next five, sometimes blocking stars and sometimes studded with them. I'd been getting up every hour to check, but it was not until 1:15 AM that the show started. I could not pull myself away despite the nip in the early morning air, and spent almost an hour and a half observing the phenomenon. It was only when the last streamers had paled that I went inside and crawled under the electric blanket to take the chill out of my legs and hands. Worth losing sleep over? Absolutely! And if there's a second act tonight, I'll be out there.
Addendum: You get a bonus today. Sunspot AR3664 (the culprit) can be seen in the lower left quadrant.
