The second night was also cleared and very cold night. Being experience last night, we awaited appearance of aurora with single-lens reflex camera with tripod. As our expectations, aurora appeared and started dance above us. Very feeble light extending almost the whole sky changes very frequently in terms of second, and its color tint is too delicate to observe through the widow glass. This is why all the observers are enduring outside in the coldness with naked eyes, and recording actual movement is very difficult.
Camera is enforced to function in a refrigerator temperature.
I could not find proper words how to describe this phenomenon. The second night distinguished so-called 'power observers group' and 'beginners group', just like PC users. When I felt insensitive due to coldness, I escaped to the cottage with degree zero, while much younger daughter aiming an astronomer still continued to watch in the outside. The third night we observed from the top of the skiing crest at the suburb of Fairbanks. It is ideal place to look 360 degree panoramic view, though cold wind blew.
