Noise, in the cracks of the normal clouds, there are light streaks.

Edit. And there were little streaks and waves everywhere. Abundant mixed normal clouds caused uncertainty, but the clearly bright bands of the weaving pattern confirmed the observation. At two, the skies opened up to reveal a vast spectacle, with broad belts rising to 20 degrees in the northwest at 2:42. The first picture shows the northwest-north lane at 2:01.
