The blood-red night brown colored the creeping mist from the river as the mosquitoes looked for a suitable injection site. There were only a few reddish gauze strips in the sky, but with the naked eye the clues could not be distinguished from the illuminating night clouds. The observation site had good visibility from northwest to northeast and in that respect the result was negative. Figure 1 at 0:11, processed Figure 2 at 2:01. From northeast to southeast, the forest blocked visibility below ten degrees. There could have been something in principle there.
Edit. It makes sense or not, but I rassed the picture at 1:42 as an editing exercise. The driver and the pieces of the Big Bear stand out well. The right forepaw is in the north and there is something lighter behind the gauze at a height of about 10 degrees, but the nega does not turn positive from such a vague simmer. The color treatments bring out how the turbulent sky was, even though visually the conditions seemed satisfactory.
