NASA's^[1][2][3] eclipse catalogue gives the instant of greatest eclipse as 20:23:11 UT on 2044-02-28 (20:24:39 TD, the two separated by delta-T), from Saros series 121. Eclipse circumstances are computed from orbital mechanics, so the date and time are exact centuries ahead.

Annular Solar Eclipse Crosses the South Atlantic

The Moon's shadow touches down at 20:23:11 UT on 2044-02-28, and the annular phase lasts up to 2 minutes 27 seconds along a path 2250.6 km wide crossing the South Atlantic. A partial eclipse is visible from Antarctica and South America.

An annular solar eclipse on 2044 Feb 28, catalogued by NASA/GSFC as sequence 09605, relative number 25, of Saros series 121^[1][2][3]
Greatest Eclipse falls at 20:23:11.9 UT at 62°10.7'S 025°34.4'W, with the Sun only 3.7° above the horizon, a path 2250.6 km wide and a central duration of 02m27.2s^[1]
Greatest Duration is a separate, earlier point at 20:16:21 UT at 64°41'S 014°00'W, where the Sun is on the horizon (altitude 0.0°), the path is 2594.5 km wide and annularity lasts 02m27.4s; the Google-map page states the same figure, ‘In this case, the Greatest Duration is 02m27.4s’^[1][2]
The antumbral path is tabulated at 120-second intervals from 20:06 to 20:40 UT with ‘Limits’ rows at each end, lying entirely in southern latitudes of roughly 52°S to 70°S; central-line rows appear only between 20:18 and 20:30, where path width ranges from 2172 km to 2559 km and the Moon/Sun diameter ratio is 0.959-0.960^[1]
The Saros 121 catalog gives the same instant in Terrestrial Dynamical Time as 2044 Feb 28 20:24:39 TD with ΔT = 88 s, classifies it ‘As’, and lists gamma -0.9954, magnitude 0.9600, Sun altitude 4°, no path width and a central duration of 02m27s — its blank width column against the path page’s 2250.6 km at greatest eclipse^[1][3]
This is the longest annular eclipse of the whole of Saros 121, at 02m27s^[3]
Annularity can only be seen between the blue northern and southern path limits and is longest on the red central line; yellow lines mark maximum eclipse at 10-minute intervals^[2]
Predictions use the VSOP87/ELP2000-85 solar and lunar ephemerides with ΔT = 87.1 seconds, and exclude the lunar limb profile, which ‘may shift the limits of the eclipse path north or south by ~1-3 kilometers, and change the eclipse duration by ~1-3 seconds’ and move Greatest Duration by ~10-20 km^[1][2]
Saros 121 runs 1262.11 years over 71 solar eclipses, from a partial on 0944 Apr 25 to a partial on 2206 Jun 07; only 11 are annular, and this one is followed by the series’ first closing partial on 2062 Mar 11^[3]
All calculations are by Fred Espenak, NASA’s GSFC, who ‘assumes full responsibility for their accuracy’^[1][2][3]
