06_NLC_1.jpg Canon 60Da 17-40mm @ 39mm f/4 4s ISO 800br/ 20150623 07:46 UT. North of Barrhead, Alberta. Another simple camera on a tripod setup, singl image. Here in central Alberta the downside to our perpetual summer twilight is sitting in a sweetspot for viewing noctilucent clouds. This shot is only a few minutes after local midnight (01:34) a couple of days after the solstice. We got really lucky because we had gone to a dark site for an anticipated auroral storm (which arrived as we were packing up) and were rewarded with this splendid display, the quot;silver foxquot;.
