This web page shows the moon's terminator movement during a 1.9-hour interval. The images were made on the evening of 2007.05.23 when the moon was almost first quarter.

Figure 1. Overview showing area of next image. (This image was taken in 7 years earlier, when the phase was ~1  day later than the phase for the rest of the images.)

Figure 2. Image of 11x17 'arc region on first quarter moon. Greatly reduced in size to fit on one web page view (the last image on this web page is a full-scale version of this one).
