Would-be astronomers, clear your afternoon schedule: A total solar eclipse will occur across South America later today, starting in Chile at 4:38 p.m. Eastern time and moving eastward across the continent, ending outside of Buenos Aires, Argentina at 4:44 p.m. EDT, CNN reports. Depending on where the eclipse is viewed from, it could last up to about four minutes.
The path of totality, where the moon completely blocks the sun (like in the photo above), will follow a 90-mile-wide band through the southern Pacific Ocean and then across Chile and Argentina—NASA has a handy map outlining the exact path of totality. Outside of that area, a partial solar eclipse will be visible through a much wider swath of South America.
According to Paul Cox, chief astronomical officer at the Slooh Community Observatory, this particular event should be especially dramatic: Since it comes late in the day during the South American winter, the total eclipse will occur while the sun is hanging low in the sky in Chile and Argentina.
If you’re lucky enough to be in the path of totality, it should be an awe-inspiring sight (just make sure you don’t look directly at the sun while it’s partially blocked, since that can cause serious eye damage). But you don’t have to be in South America to see it—for the rest of the world, there are several live streams available to view the eclipse.
NASA will air a live feed of the eclipse starting at 3 p.m. EST today, and there will be live commentary in English and Spanish from 4 to 5 p.m. Check it out below:
Can’t tune in for this eclipse? Don’t worry, there are others coming up. According to NASA, another eclipse will pass through the South Pacific, Chile, Argentina, and the South Atlantic in 2020, and there will be an eclipse in North America in 2024.
