The right third of the MODIS mosaic shows the eastern United States at about 12:10 p.m. Eastern Time (16:10 Universal Time), before the eclipse had begun. The middle part was captured at about 12:50 p.m. Central Time (17:50 Universal Time), when the eclipse was in progress in the center of the country. The left third of the image was collected at about 12:30 p.m. Pacific Time (19:30 Universal Time), after the eclipse had ended. The VIIRS mosaic is similar, but it shows the shadow at 2:30 p.m. Eastern Time (18:30 Universal Time), when it had reached the eastern United States. Note that VIIRS has a different orbital geometry and a slightly wider swath than MODIS.
