A panorama of NLCs – noctilucent clouds – aka PMCs or polar mesospheric clouds, taken on June 20, 2022 about 11:40 pm MDT, from home in southern Alberta. After many cloudy nights and some clear nights with no NLCs, this was my first sighting since June 1. The bright luminous mesospheric clouds lit by sunlight at high altitude contrast with the dark tropospheric clouds to the left at low altitude.

The bright star Capella in Auriga, low in the north and circumpolar from my latitude of 51° N, is left of centre. The stars of Perseus are at upper right.

This is a panorama cropped from 9 segments of 5-second exposures, with the RF24-105mm lens at f/4 and 80mm, and with the Canon R5 at ISO 400. Stitched with Adobe Camera Raw.
