A panorama of the solstice twilight and twilit clouds at Crawling Lake Reservoir, Alberta, on June 22, 2019. I was on site to capture noctilucent clouds which did not materialize this night. However, high clouds in the twilight mimicked NLCs – I shot this to record those “fake” NLCs. But these clouds moved quickly from NW to SE like nornal weather clouds. Jupiter is bright at left to the southeast. Vega and Altair are in the darkest part of the sky at left of centre. My RAV4 poses at left. Stitched with ACR.
A very bright and structured display of noctilucent clouds (NLCs) on June 19, 2019, taken from southern Alberta in the solstice twilight at 11:31 pm MDT, before they began to fade as the sun angle decreased. This was from the grand old barn site near home. Earlier in the evening – just 30 minutes earlier — there were wisps of NLCs much higher and even overhead, but they soon faded leaving this bright horizon display which lasted another hour. This display was in the northwest, centered at about 30° west of due north. This is a single exposure with a 50mm Sigma lens on the Sony a7III, for 1 second at f/2.8 and ISO 400.
