Visibility III / V
After midnight, the illuminating night clouds began to stand out clearly in the far north. At its brightest, the show was around 00:15, after which the night clouds dimmed quickly. Sometimes at two o'clock the lower clouds came to the fore, so there is no observation in the morning. The interval between the first and second images may be about 20 min, but during this time, due to the location of the sun, the glow was already really down on the horizon.
