I was excited to see an article in my news feed describing a comet passing close enough to the sun to fit in a telescopic field of view. Called SOHO-5008, it was a sungrazer, a comet passing so close to the Sun it would appear in coronagraph images by the SOHO solar satellite. This one had been identified in SOHO images the morning of the eclipse and several people found that they had captured it in their eclipse images. Later that day, it had burned up in the Sun.

I pulled up my own images from totality and found that I had captured it, too! It took bumping up the exposure far more than I usually would but, once I did that and made a few other adjustments to bring out more detail, there it was. Here is an edit with labels, noting some of the brighter stars visible from constellation Pisces and adding an enlarged inset for the comet.
