This series of images demonstrates the changing appearance of the Earth's shadow on the Moon, called the umbra. The images are arranged in sequence chronologically from right to left and descending. The first two images at top were taken before the start of totality and show the right limb of the Moon being illuminated by sunlight with the rest of the disk in the umbra. The third image, at middle right, was taken at the start of totality at 7:01 PM, while the fourth image, at middle left, was taken about nine minutes before mid-eclipse. The fifth image at bottom right was taken at the end of totality, while the final image was taken two minutes later and shows the bottom limb of the Moon being illuminated by sunlight. While the umbra is mostly reddish in color due to the reddening of sunlight as it passes through Earth's atmosphere, the edge of the umbra appears bluish in the top two and bottom two images. This is due to the absorption of red light by ozone in the Earth's upper atmosphere.
