May 26, 2021 — Total Lunar Eclipse — San Juan
The animation shows what the eclipse approximately looked like in San Juan. Stages and times of the eclipse are outlined below. All times were local time (AST) for San Juan.
| Time | Phase | Event | Direction | Altitude |
|---|---|---|---|---|
| 4:47 am Wed, May 26 | Penumbral Eclipse begins The Earth's penumbra start touching the Moon's face. |  243° | 12.0° | |
| 5:45 am Wed, May 26 | Partial Eclipse begins Partial moon eclipse starts - moon is getting red. 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 West-southwest for the best view of the eclipse. | 247° | 0.5° | |
| 5:46 am Wed, May 26 | Maximum in San Juan This is the moment when the eclipse reaches its greatest magnitude while the entire Moon is above the horizon in San Juan. The true maximum point of this eclipse cannot be seen in San Juan 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 West-southwest for the best view of the eclipse. | 248° | 0.2° | |
| 5:48 am Wed, May 26 | 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. | 248° | -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.
The total phase of this lunar eclipse was not visible in San Juan, but it could be observed there as a partial lunar eclipse. The Earth's shadow covered only a small portion of the Moon.
