Visibility II / V
It was a dim but (again) wide performance. At first, it seemed to be content with the belts of the northwest at low (Fig. 3), but around the reddish standard cloud patches, wide areas of gauze stood out and also brought out the clusters of waves. The rattlesnake group in the first image, which was 15 degrees above the zenith in the south, has finer structures. Rotating the polarizer, the gauze and ripple could be inferred as night clouds. Together, gauze was present almost everywhere except low in the north and east. When the canola was made from the window, individual pieces of belt were seen in the northwest and north for another two years.
