An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Annularity was visible from the islands of Pulo Anna and Merir in South Pacific Mandate in Japan (now in Palau) and Wake Island on July 10, and Midway Atoll on July 9.
