July 29, 2018. We had a thunderstorm pass over just at sunset, producing this rainbow that got fainter as the sun actually set. This was captured with my wide angle lens; I'm not sure what the black is on the left; it's not a smudge, maybe some reverse lens flare? There was also lightning framed by the rainbow but I wasn't able to capture that (it was pretty spectacular though). Today was a rest day, especially for my glutes, and I spent it working on the analysis engine for gRSShopper.
