Annular Solar Eclipse Crosses the South Indian Ocean
- An annular solar eclipse on 2043 Oct 03, catalogued by NASA/GSFC as sequence 09604, relative number -27, of Saros series 154[1][2][3]
- It is a non-central eclipse: the path page is headed ‘Non-Central Eclipse’ and every central-line, diameter-ratio, Sun altitude and azimuth, path-width and duration column in its table is filled with ‘-’, so the source gives this eclipse no central-line duration or path width at all[1]
- The Saros 154 catalog agrees, typing it ‘A-’ with gamma -1.0102, magnitude 0.9497 and blank path-width and central-duration columns, at 2043 Oct 03 03:01:49 TD with ΔT = 88 s[3]
- The links disagree on duration: the Google-map page states ‘In this case, the Greatest Duration is 07m45.4s’, a figure neither the path table nor the Saros catalog supports for a non-central eclipse with no central line[1][2][3]
- What the path table does give are the northern and southern limits at 120-second intervals from 02:52 to 03:08 UT, opening at limits 56°07.5'S 038°56.5'E and closing at limits 65°48.1'S 031°07.4'E — the antumbra only grazing high southern latitudes[1]
- Predictions use the VSOP87/ELP2000-85 solar and lunar ephemerides with ΔT = 86.7 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’; fuller predictions are normally posted 12-18 months beforehand[1][2]
- Saros 154 is a young series, begun with a partial on 1917 Jul 19 and running 1262.11 years over 71 solar eclipses to a partial on 3179 Aug 25; this eclipse is its first umbral one, following the partial of 2025 Sep 21 and preceding the annular of 2061 Oct 13, which at 03m41s is the series’ longest annular[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 03:00:21 UT on 2043-10-03 (03:01:48 TD, the two separated by delta-T), from Saros series 154. Eclipse circumstances are computed from orbital mechanics, so the date and time are exact centuries ahead. This eclipse is non-central and has no published path table, so its place is the catalogue position, good to the whole degree.

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.
