photo of the week 50Last December (2012) I was snow shoeing in Pallas-Yllästunturi National Park in Finnish Lapland after nine in the evening. It was a new moon and the stars were visible. Suddenly, I saw some aurora borealis on the night sky for some minutes before the clouds covered the whole sky. I had a couple of minutes time to take photographs before the stars disappeared quickly. I felt I was in a hurry and there was not much time to figure out what would be the perfect composition. The clouds arrived so quickly! I had to forget my plan to hike further up the slope to higher elevations. There is a parking lot and a Visitor's Center of this national park behind my back a couple of hundred of meters away from me. That gives the light, which illuminates the trees. This past and the next winter are supposed to be the peak winters for aurora borealis (and the peak for the activity of the sunspots) on this 11-year cycle.I was hoping to return to this same place during the winter but I never saw aurora borealis, the northern lights again on this national park. As important as the aurora borealis colors in an image are for me, I am also looking to have something interesting in front of them, for example, the snow covered trees. The beautiful starry night sky is also a bonus to be seen together with the northern lights. Another try next winter again!My ISO is 2500, shutter speed 20 seconds and aperture 3.5.
