August 17, 2027 — Penumbral Lunar Eclipse — Summit Camp
The animation shows what the eclipse approximately looks like in Summit Camp. Stages and times of the eclipse are outlined below. All times are local time (CGST) for Summit Camp.
| Time | Phase | Event | Direction | Altitude |
|---|---|---|---|---|
| 4:24 am Tue, Aug 17 | Penumbral Eclipse begins The Earth's penumbra start touching the Moon's face. 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 Southwest for the best view of the eclipse. |  221° | -0.1° | |
| 4:25 am Tue, Aug 17 | Maximum in Summit Camp This is the moment when the eclipse reaches its greatest magnitude while the entire Moon is above the horizon in Summit Camp. The true maximum point of this eclipse cannot be seen in Summit Camp 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 Southwest for the best view of the eclipse. | 221° | -0.2° | |
| 4:26 am Tue, Aug 17 | Setting | Moonset Setting, but the combination of a very low moon and the total eclipse phase makes the Moon so dim before it sets, that it might disappear from view some time before it sets. | 221° | -0.2° |
| 6:13 am Tue, Aug 17 | Not directly visible | Maximum Eclipse Below horizon | 246° | -6.8° |
| 8:03 am Tue, Aug 17 | Not directly visible | Penumbral Eclipse ends Below horizon | 272° | -14.1° |
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 (Aug 17)
In the past, this day was cloudy 54% of the time (since 2000).
