As the moon passes between the Sun and the Earth, the Solar Eclipse begins over the Southern Pacific Ocean mid-afternoon as it moves the lunar shadow will touch the western coast of South America, near La Serena, Chile, at 3:22 p.m. local time. Totality begins in La Serena at 4:38 p.m local time. The total eclipse moves to the southeast, ending near Chascomús in eastern Buenos Aires province of Argentina, at 4:44 p.m. local time. Weather permitting people in those countries will experience the midday darkness of a total eclipse.
Depending on where someone is watching Nasa stated the totality (when the sun is completely dark) will last up to 4 minutes and 3 seconds and that a partial eclipse will be visible to people in Bolivia, Peru, Ecuador, Paraguay, and Uruguay, and parts of Brazil, Colombia, Panama and Venezuela.
Astrologically the Sun and Moon will be in the sign of Cancer July 2, 2019 and forms a wide trine to Neptune Pisces while opposing Saturn Capricorn. The rulership, at the beginning of the eclipse, falls under the sign of Scorpio and the planets Mars and Pluto. Scorpio and Cancer are water signs, so it proves interesting this eclipse begins in the Pacific Ocean and ends in the Atlantic Ocean.
At this time, Mars is in Leo right next to Mercury and both are forming a square to Uranus Taurus in the heavens. Pluto Capricorn has Saturn slowly coming close to it by December 2019 then January 2020 even closer.
In attempting to forecast how the eclipse will effect South America, I would say the fault lines of Mother Earth will activate and some of the volcanoes in South America will act up over the next six months. That said, I know faults and volcanoes act up on a regular basis, however the eclipse will have an effect on earth immediately and continues over the next six months. Therefore, people living in South America close to volcanoes may want to pay attention to any hints of rumbling or sudden activity. As for earthquakes, especially Chile be more aware of your vulnerability, as you do experience quakes fairly often, even tsunamis, so practice preparedness.
