Bob was looking through his photos from April 24, 2021 and realized that he captured a moonbow in this photo. He was trying to capture a moonbow from this perspective, but thought that clouds from a passing storm wouldn't allow enough moonlight through to create a moonbow or that the angle from this perspective was wrong for seeing one. See our other postings on moonbows for a description of what they are.
In this photo, which he shot from the Yosemite Falls Trail, is Upper Yosemite Falls, the moonbow hovering over the Middle Cascade, and Half Dome.
