Looking for the Northern Lights, finding airglow and a colorful sky

The new moon occurred on the morning of Sunday 04 Aug.  Milky Way viewing will get progressively harder as the moon waxes in the evening sky.  There are reports of auroras visible from some locations in Colorado.  In spite of substantial variable cloud cover, it seemed worth the effort to take some images Sunday evening to see what turned up .  The sky was noticeably brighter than average, with sqml=21.2 mpsas. 

All images taken with a Sony A7iii + FE 20mm f/1.8G lens, ISO 1600, 30 s.

 The constellation Corona Borealis is in the center of the above image.  Astronomers world-wide are watching this constellation for the expected outburst of the recurrent nova T CrB.
