Double rainbow at sunset

Richard Hasbrouck in Truchas, New Mexico caught this double rainbow on June 7, 2014. He wrote:

Near sunset, to the east the 13,000-ft Truchas peaks were obscured by rain clouds. However, there was a narrow band of clear sky just above the western horizon. The setting sun was still up in the storm clouds but I anticipated that when it entered the clear area there might be a brief rainbow. For a change I was ready—had the camera ready to go. Bingo, the sun made its brief appearance and produced the attached double rainbow.

Canon EOS5D Mk III, Canon 16-35 mm, f/2.8 lens with a circular polarizer. Lens at 16 mm,; ISO 400, f/2.8, 1/30 sec handheld (auto-stabilizer ON).

Processed the Camera RAW image in Lightroom and CS6 and straightened the tilted buildings (caused by the wide-angle lens) on the right and left edges.?

Thank you, Richard!
