| 4:08 pm Thu, Dec 20 | Maximum in Sidney This is the moment when the eclipse reaches its greatest magnitude while the entire Moon is above the horizon in Sidney. The true maximum point of this eclipse cannot be seen in Sidney because the Moon is below the horizon at that time. Since the Moon is near the horizon at this time, we recommend going to a high point or finding an unobstructed area with free sight to Northeast for the best view of the eclipse. | 55° | 0.2° | |

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.
