Animation: How the Partial Lunar Eclipse Looked

The total phase of this lunar eclipse was not visible in Ulaanbaatar, but it could be observed there as a partial lunar eclipse. The Earth's shadow covered a large portion of the Moon, so this was still a nice sight.

The maximum part of the eclipse occurs when the Moon is close under the horizon. The best time to view the eclipse in Ulaanbaatar would be around this 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.
