Expectations

Midnight on the Taiga

Last evening began with very high expectations : the forecast was for clear skies, and the aurora predictions were for another busy night. And when the first lights appeared early – about 8 pm – we settled in for what we thought would be a long, busy night.

Then began what can only be called the “dressing ritual”, the donning of multiple layers of clothing: hats, scarves boots, gloves, over-gloves and over-mittens. (At -35 C., you need to be pretty well-padded to spend the evening standing around outside.)

For an hour or so, there was a lot of activity, with waving bands of green filling the sky. Loops formed and then untied themselves, and fleeting curtains of dancing light appeared and then, just as abruptly, vanished.

Green is the most common color in the aurora, the result of the excitation of oxygen molecules high in the atmosphere caused by incoming charged solar particles. Other colors – red, purple, violet – are possible, but are more commonly associated with stronger solar events. Some of these are not visible to the human eye, but are recorded by film and sensors. So it was not until I had a chance to open images on the laptop that it became clear that tonight’s lights did not have some of the red tinges of previous nights.

Whether or not that itself was a kind of indicator of diminishing activity, the lights faded quickly before midnight, and never really re-formed for the rest of the night. What was supposed to be a Big Night, became a quiet evening, and a chance to catch up on some much-needed sleep.

Today, meanwhile, the skies are clear again, and expectations are as high as ever for tonight.  In about 12 hours, we’ll see what happens.

p.s. I have been told that this is not really a “live-blog” since I’m not giving minute-by-minute reports on the aurora activity. True enough – but frankly I’d rather be out shooting!
