A world map showing where the eclipse is visible at different phases. Contours mark the boundary around the part of Earth where each phase is visible. The start of the partial phase, for example, is visible everywhere within the orange contour. The map is centered on 63°8'W, the sublunar point at greatest eclipse (the longitude where the Moon is highest in the sky). The eclipse can't be seen in the gray areas outside the contours.
