It stayed put for a very long time--long enough for me to grab the camera and snap several photos. We could see nearly the entire arc and the eastern third was a double, barely visible.
Rain drops were on the windows, but didn't hurt the images much. The colors on the northern portion were amazingly intense. Luckily, I had time to change the camera settings several times in an attempt to capture the show as close as possible to how it looked from our living room.
