I spent the past week up in the Northwest Territories. A colleague and I were back to our Wood Buffalo National Park site to install satellite communications and modify some of our equipment. We lucked out with the weather, although the Tuesday was about -24° Celsius, on the Wednesday it got up to -6° C. There was about 30cm of snow on the ground. This was the sunrise from the airport taken on the Friday. Sunrise was around 9:00am and sunset at 4:15pm.
