Night has returned to the far north, and with it comes the possibility of viewing the northern lights once again. Earth is constantly being bombarded with material from the sun, igniting huge displays of aurora near the poles during episodes of peak solar activity. Such displays are possible year-round, however, they can only be seen after the sun goes down. Something that doesn't happen during the summer months at or near the arctic circle. Late last night, several hours after sunset, Casey and I were treated to a brilliant fall aurora; the first showing of the 2016/17 season. Bright green bands swirled above our cabin, lighting up our driveway like a giant nightlight. Nature's fireworks are much more pleasant to watch when temperatures remain above freezing.
