Comet NEOWISE had its closest approach to the Sun back on July 3. Since then it has been heading back to the outer solar system but not before making a pass by Earth. On Thursday it reached it closest distance to Earth and I happened to have clear skies.

The sunsets on Lake Michigan often end with a green flash caused by the atmosphere's layers acting like a prism to make the Sun's image slightly split into the separate spectral colors. This effect causes blue and green, which have the shortest visible wavelengths, to be the last to disappear over the horizon.
