6 February 2027: The Path of the Ring

The annular path enters Argentina from Chile near Esquel, where the ring lasts 7 minutes 31 seconds, and runs north-east across Río Negro to the coast. Viedma has 7 minutes 10 seconds at 12:13 p.m. and Bahía Blanca, near the northern edge, 4 minutes 4 seconds. In the south of Buenos Aires province Tandil has 5 minutes, Necochea 7 minutes 42 seconds and Mar del Plata 7 minutes 37 seconds at 12:28 p.m., with the Sun 66 degrees high. From there the ring continues over the sea to Uruguay, where Punta del Este has 5 minutes 34 seconds. It is a summer Saturday on the Atlantic coast, in the middle of the holiday season, and the eclipse happens close to midday.

Buenos Aires and the Rest of the Country

Bariloche misses the ring narrowly: the path passes just to the south and the city sees 85%. In Buenos Aires the eclipse begins at 10:46 a.m., reaches 82% at 12:31 p.m. and ends at 2:15 p.m., a crescent Sun high over the Río de la Plata. Rosario has 74%, Córdoba 64%, Mendoza 62% and Ushuaia 53%. Inside or outside the path the rule is the same. In an annular eclipse the Moon never covers more than about 86% of the Sun's area, the sky does not go dark, and looking at the ring without a certified filter damages the eye exactly as looking at the uneclipsed Sun does. Eclipse glasses stay on for the whole of it.

2026 and August 2027: Not Visible Here

The annular eclipse of 17 February 2026 over Antarctica was seen from Argentina only at the southern tip, where 3% of the Sun was covered in Ushuaia. The total eclipses of 12 August 2026 and 2 August 2027 both cross Spain and are invisible from the whole of South America. After February 2027 there is little for several years: on 26 January 2028 an annular eclipse over Brazil is partial in the north and centre of the country, 8% in Córdoba and under 2% in Buenos Aires, and on 11 July 2029 a small partial eclipse reaches Patagonia, with 9% in Ushuaia.

Total Eclipses in Argentina: 2019, 2020 and 2064

Argentina shared two total eclipses with Chile. On 2 July 2019 the shadow reached San Juan province just before sunset, and Buenos Aires saw the Sun go down 99.7% covered. On 14 December 2020 totality crossed northern Patagonia, with 2 minutes 6 seconds at Las Grutas on the coast of Río Negro, while Bariloche had 96%. The next total eclipse at any of the places on this page is on 12 August 2064, when Bahía Blanca has 1 minute 58 seconds of totality and Buenos Aires sees 81%. Later still, the annular eclipse of 4 November 2078 brings a ring of 7 minutes 50 seconds to the same city. The 2027 eclipse is the one that this generation can actually plan for.
