This was on a mid-October night when the Big Dipper rides low in the northern sky from this latitude of 53° N.13898633 - A panorama of an arc of noctilucent clouds over a ripening field of yellow canola, on July 14, 2022 from southern Alberta near Hussar. This was about 11:20 pm MDT with the NLCs near their peak. They reached a little higher when they first appeared a few minutes earlier in the brighter sky, but capturing them is always a balance between getting them at their maximum height vs. the darkness of the sky background to make the fainter structures stand out. The foreground is illuminated mostly by twilight, and I have brightened it to bring out the canola colours and the colour contrast between earth13898071 - Mars, Venus and Jupiter (in that order from top to bottom) in a triangle, in conjunction, at an old farmstead near Vulcan, Alberta, in the morning twilight, October 28, 2015. Illumination is from the nearly Full Hunter’s Moon in the west. The trio of planets were in Leo in a fine conjunction not to be repeated until November 21, 2111.

The blue band on the horizon is the shadow of the Earth cast onto the atmosphere opposite the sunset point. The pink Belt of Venus above the shadow is from red sunlight still illuminating the upper atmosphere, an effect that lasts only a few minutes at sunset or sunrise, and requires a very clear sky to show up, as it was this night.13898781 - Mars (bottom) and Saturn in conjunction at right, and the Milky Way at left, in deep blue twilight before the sky got filly dark, over the old corral of the 76 Ranch, in Grasslands National Park, Saskatchewan, August 27/28, 2014.
