Total Solar Eclipse Crosses Russia
- A total solar eclipse on 2043 Apr 09, catalogued by NASA/GSFC as sequence 09603, relative number -16, of Saros series 149[1][2][3]
- It is a non-central eclipse: though the path page is titled ‘Total Solar Eclipse of 2043 Apr 09’, its table is marked ‘Non-Central Eclipse’ and carries no central-line, ratio, altitude, azimuth, width or duration values — so the source gives no central-line duration or path width[1]
- The Saros 149 catalog agrees, typing it ‘T+’ with gamma 1.0031, magnitude 1.0095 and blank path-width and central-duration columns, at 2043 Apr 09 18:57:49 TD with ΔT = 87 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]
- The path table holds only three rows: limits at 62°16.0'N 166°38.9E (northern and southern limits identical), a single 18:56 UT row with a northern limit at 61°15.8'N 152°00.8'E and the remaining columns blank, and closing limits at 63°54.9'N 165°55.0'E[1]
- Predictions use the VSOP87/ELP2000-85 solar and lunar ephemerides with ΔT = 86.4 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 149 runs 1262.11 years over 71 solar eclipses, from a partial on 1664 Aug 21 to a partial on 2926 Sep 28, with 17 total; this eclipse is the series’ first umbral one, following the partial of 2025 Mar 29 and preceding the total of 2061 Apr 20 (02m37s, 559 km)[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 18:56:22 UT on 2043-04-09 (18:57:49 TD, the two separated by delta-T), from Saros series 149. 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.
