August 17, 2027 — Penumbral Lunar Eclipse — Alcobaça
The animation shows what the eclipse approximately looks like in Alcobaça. Stages and times of the eclipse are outlined below. All times are local time (WEST) for Alcobaça.
| Time | Phase | Event | Direction | Altitude |
|---|---|---|---|---|
| 6:24 am Tue, Aug 17 | Penumbral Eclipse begins The Earth's penumbra start touching the Moon's face. Moon close to horizon, so make sure you have free sight to West-southwest. |  248° | 4.3° | |
| 6:46 am Tue, Aug 17 | Maximum in Alcobaça This is the moment when the eclipse reaches its greatest magnitude while the entire Moon is above the horizon in Alcobaça. The true maximum point of this eclipse cannot be seen in Alcobaça because the Moon is below the horizon at that time. Moon close to horizon, recommend going to a high point. | 252° | 0.8° | |
| 6:52 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. | 253° | -0.2° |
| 8:13 am Tue, Aug 17 | Not directly visible | Maximum Eclipse Below horizon | 265° | -15.6° |
| 10:03 am Tue, Aug 17 | Not directly visible | Penumbral Eclipse ends Below horizon | 284° | -35.5° |
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.
