Mars 2020-10-18 (UT)
Humidity is high on a clear night after a long absence.
After midnight, seeing improved a little and we could see around 0 degrees longitude on the surface of Mars.
The SPC is small. Infrared images have higher resolutions and fine structures can be seen. Mist and clouds can be seen in the UV image at dawn (right) and in the evening.
A meandering pale cloud can be seen in the center.
