Puerto Rico is set to experience a celestial phenomenon on the night of this Tuesday, September 17th, and during the early hours of Wednesday, the 18th, when a partial lunar eclipse will flood various cities in the Caribbean country, although it will be relatively small. This astronomical spectacle will be visible in North and South America (specifically Ecuador), Europe, most of Africa, western Asia, and parts of Antarctica. If you can’t see the eclipse in person, there will be several live webcasts that allow you to witness it live from the comfort of your home, such as the one hosted by NASA TV.

The map shows where the partial lunar eclipse will be visible on September 17-18. At that moment, the lunar eclipse is visible wherever the Moon is above the horizon. Because the geometry of a lunar eclipse requires the Moon to be directly opposite the Sun in the sky, the Moon can be seen above the horizon wherever the Sun is below the horizon. | Credit: in-the-sky.org
