Visibility II / V
It wasn’t until five years earlier that I first managed to see and photograph the illuminating night clouds in the same spot. At the beginning of this year’s night cloud season, I had only received backup images of the negative observation, but now the clouds had returned. The air was moist, with a temperature of 16 degrees and a relative humidity of 79%. Only a couple of mosquitoes sought a suitable injection site. The night clouds were dim, but the performance first extended from northwest to northeast as the northeast group slid by three to the east and in the northwest the clouds reached 40 degrees. First image northeast 2.20, panorama 2.07 and third image east 2.35.
