Pretty sunset clouds

The weather on Friday was rainy and cloudy, but it partially cleared around sunset with these spectacular clouds to the north of the UofA campus.  The white building at center is the National Optical Astronomy Observatories headquarters and this area is the center of the Astronomical capital of the world with the Lunar and Planetary Lab where I work on the right edge of this fisheye view and Steward Observatory on the left edge.  Behind me is the Flandrau Science Center and planetarium. This image was taken with my 10mm fisheye lens on my 70D with an exposure of 1/1000 seconds at f/5, ISO 400.
