Maximum in Rapid CityThis is the moment when the eclipse reaches its greatest magnitude while the entire Moon is above the horizon in Rapid City. The true maximum point of this eclipse cannot be seen in Rapid City 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 East-northeast for the best view of the eclipse.
The curvature of the shadow's path and the apparent rotation of the Moon's disk is due to the Earth's rotation.
The total phase of this lunar eclipse is not visible in Rapid City, but it can be observed there as a partial lunar eclipse. The Earth's shadow covers a large portion of the Moon, so this is still a nice sight.
