Mare's Tails At Dusk

Mare's Tail (cirrus incinus) clouds streak the horizon around 9:30 PM, Sunday, July 8, 2012 looking WNW from just west of Christ Community United Methodist Church in Marion, Iowa. Sunset was about 45 minutes earlier. The street visible at lower right is Forest Lane, just south of East Robins Road in Marion, and just east of the Marion/Cedar Rapids city border. This image is a 1.5-second exposure at f/13, 640 ISO and 200mm focal length.
