In September, I took a photo of the Capitol during the blue hour (the period of twilight each morning and evening when there is neither full daylight nor complete darkness) with the dome reflected in one of the two giant skylights of the Capitol Visitor Center (which lies underground, just in front of the Capitol). Normally, a small amount of water surrounds each of the skylights. At the time, the water wasn't present, I assumed because of an ongoing drought. The water has since returned and I recently visited the Capitol again to see if I could improve on my previous photo with the water present.

Here are two photos. I took the first just before the start of civil twilight and the second right at the start of civil twilight (dusk). I took the photos only 11 minutes apart and as you can see, in that 11 minutes, the light changed considerably.
