Annular Solar Eclipse Crosses the South Atlantic
- An annular solar eclipse on 2032 May 09, catalogued by NASA/GSFC as sequence 09579, relative number -14, of Saros series 148[1][2][3]
- Greatest Eclipse falls at 13:25:23.8 UT at 51°15.5'S 007°03.5'W, with the Sun 19.9° up, a path only 43.7 km wide and a central duration of 00m21.9s[1]
- Greatest Duration is elsewhere and much longer: 14:03:01 UT at 55°41'S 030°39'E, with the Sun on the horizon, a path 91.0 km wide and annularity lasting 00m43.1s — twice the duration at greatest eclipse; the Google-map page gives the same 00m43.1s[1][2]
- The antumbral path is tabulated at 120-second intervals from 12:48 to 14:02 UT, the central line running from 69°57.6'S 042°31.2'W (87 km wide, 00m40.8s) to 55°41.0'S 030°39.2'E (91 km, 00m43.1s), entirely in southern latitudes of about 69°S to 49°S; the Moon/Sun diameter ratio runs 0.990 at the limits to 0.996 near mid-eclipse[1]
- The Saros 148 catalog gives the same instant in Terrestrial Dynamical Time as 2032 May 09 13:26:42 TD with ΔT = 79 s, gamma -0.9375, magnitude 0.9957, path width 44 km and central duration 00m22s — the greatest-eclipse figures rounded, not the 00m43.1s maximum[1][3]
- This is the longest annular eclipse of the whole of Saros 148, at 00m22s, one of only two annulars in the series[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 = 78.2 seconds, and exclude the lunar limb profile, whose corrections ‘may shift the limits of the eclipse path north or south by ~1-3 kilometers, and change the eclipse duration by ~1-3 seconds’[1][2]
- Saros 148 runs 1334.23 years over 75 solar eclipses, from a partial on 1653 Sep 21 to a partial on 2987 Dec 12; this one follows the non-central annular of 2014 Apr 29 and precedes the hybrid of 2050 May 20 as the series turns total[3]
- All calculations are by Fred Espenak, NASA’s GSFC, who ‘assumes full responsibility for their accuracy’[1][2][3]

NASA's[2][3] eclipse catalogue gives the instant of greatest eclipse as 13:25:23 UT on 2032-05-09 (13:26:42 TD, the two separated by delta-T), from Saros series 148. Eclipse circumstances are computed from orbital mechanics, so the date and time are exact centuries ahead.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
