Total Lunar Eclipse on Sunday: Approximately 85% of the World Can Observe It. In Japan, the "Red Full Moon" Will Be Visible in the Early Hours of Monday, September 8th.

A total lunar eclipse, the second one this year, will occur from September 7th (Sunday) to September 8th (Monday). During the totality, the moon will be completely immersed in Earth's shadow (umbra), and only the red component of sunlight scattered by Earth's atmosphere will reach it, turning it into a "Blood Moon" (red full moon). This eclipse is exceptionally widespread, with approximately 85% of the world's population able to observe at least some stages of it, primarily in Asia, Africa, Europe, and Australia. In Japan, the penumbral eclipse is expected to begin around 0:28 on September 8th (Monday), with the partial eclipse starting around 1:27, totality from 2:30 to 3:52, the maximum eclipse at 3:11, and the partial eclipse ending at 4:56 (all times JST, Tokyo standard). Meanwhile, most of North America will not be able to observe it (Canada is generally excluded). No special protective equipment is needed for observation, but be mindful of obstructions like buildings and terrain when the moon is low. This time, the moon will appear slightly larger as it is relatively close to its perigee, making it a "slightly supermoon-like" red full moon, which is also a highlight. We provide a comprehensive guide for observers in Japan, covering observation strategies, photography settings, regional visibility, and future lunar eclipse schedules.
