| 21時54分 8月16日 (月) | Rising | Moonrise Rising, but the combination of a very low moon and the total eclipse phase will make the moon so dim that it will be extremely difficult to view until moon gets higher in the sky or the total phase ends. | 110° | -0.2° |
| 22時13分 8月16日 (月) | Maximum Eclipse Moon is closest to the center of the shadow. Moon close to horizon, so make sure you have free sight to East-southeast. Additionally, the eclipsed moon combined with dimming near horizon might make the Moon very hard or impossible to see. | 114° | 2.2° | |

How to use altitude & direction to find in the sky
The curvature of the shadow's path and the apparent rotation of the Moon's disk is due to the Earth's rotation.
During this penumbral lunar eclipse, the Earth's main shadow does not cover the Moon. As the Earth's shadow (umbra) misses the Moon during a penumbral lunar eclipse, there are no other locations on Earth where the Moon appears partially or totally eclipsed during this event. A penumbral lunar eclipse can be a bit hard to see as the shadowed part is only a little bit fainter than the rest of the Moon.
Cloud Coverage (8月16–17日 (火))
