How To Watch Online Tuesday As The First Total Solar Eclipse Since 2017 Strikes South America


Tomorrow’s total solar eclipse will be livestreamed from South America. This artist’s impression shows how the total solar eclipse of 2 July 2019 could appear from ESO’s La Silla Observatory in Chile if there are no clouds. The Sun will be quite low in the western sky and, if the skies are clear, several planets and bright stars should be also visible.

It’s finally time for another total solar eclipse. For North Americans, it’s not as easy to see as the last when the “Great American Eclipse” brought totality to a narrow strip across the USA from Oregon to South Carolina. Tomorrow’s total solar eclipse is mostly over the South Pacific Ocean, but it does make land in central Chile and western Argentina, where the eclipse will occur late in the day around an hour before sunset.

Unlike the Great American Eclipse, which occurred high in the sky, this one will be visible close to the mountains, so could make for an even more awesome a spectacle. Here’s how to follow it from afar.

What time is the eclipse?

Here are the times when you should tune in where you are. During the “Great American Eclipse” of August 21, 2017, it was possible to watch a webcast for most of the 90 minutes or so that the moon’s shadow was crossing land. Although the shape of the path of totality isn’t that much different tomorrow, most of it is at sea. In fact, only the last seven minutes of a two hour+ event is over South America. So make sure you tune in sometime before these times to watch the last few minutes of a partial solar eclipse transform into a dramatic total solar eclipse.

Totality will come to Chile at 20:38 Universal Time (UT) on 2 July 2019, and to Argentina a few minutes later. That translates as these times in North America and Europe (for the exact time where you are, visit and enter your nearest town or city):

London, UK – 21:38 BST on 2 July 2019

Paris, France – 22:38 CEST

New York, USA – 16:38 EDT

Chicago, USA – 15:38 CDT

Denver, USA – 14:38 MDT

Phoenix, USA – 13:38 MST

Los Angeles, USA – 13:38 PDT
