Hybrid Solar Eclipse Crosses the Pacific
- A hybrid solar eclipse on 2031 Nov 14, its umbral shadow path computed by Fred Espenak for NASA's Goddard Space Flight Center[1][2]
- Greatest eclipse falls at 21:06:12.3 UT at 00°38.0'S, 137°37.8'W in the equatorial Pacific, with the Sun 72.1° up, a path 38.3 km wide and a central-line duration of 01m08.3s[1]
- Greatest duration comes four minutes later and just east of it, at 21:10:26 UT at 00°58'S, 136°27'W, where the path is 38.4 km wide and the central phase lasts 01m08.4s[1]; the Google map page repeats the figure, "In this case, the Greatest Duration is 01m08.4s"[2]
- The saros catalogue lists the same eclipse as 2031 Nov 14 at 21:07:31 TD (Terrestrial Dynamical Time, against the path table's Universal Time) at 0.6°S 137.6°W, path width 38 km and central duration 01m08s[3]
- The path table gives 103 timed rows at 120-second intervals from 19:24 UT to 22:48 UT, plus opening and closing "Limits" rows, in WGS 84 coordinates[1]
- The central line starts at 19:24 UT near 25°29.6'N, 165°10.8'E in the north-west Pacific and ends at 22:48 UT near 06°43.4'N, 083°43.9'W off Panama; the outer limit rows run from 25°47.3'N, 164°18.9'E to 08°21.8'N, 078°48.5'W[1]
- The track is very narrow at its ends - 12 to 23 km wide, with the central phase lasting only 00m13s to 00m24s - and the Moon/Sun diameter ratio stays just below 1 there (0.994-0.996), the annular side of the hybrid geometry[1]
- The eclipse is member -15 of Saros 143 (sequence number 09578), with gamma 0.3078 and eclipse magnitude 1.0106[3]
- Saros 143 runs 1280.14 years from a partial eclipse on 1617 Mar 07 to a partial eclipse on 2897 Apr 23, occurs at the Moon's ascending node and holds 72 eclipses in the sequence 10P 12T 4H 26A 20P, only four of them hybrid; its longest hybrid was 2013 Nov 03 at 01m40s[3]
- Predictions use the VSOP87/ELP2000-85 solar and lunar ephemerides with ΔT = 77.9 seconds[1][2]; the catalogue row carries ΔT = 79 s[3]
- The central phase is visible only inside the path between the blue limit lines on the map and is longest on the central line, with a green GE marker at greatest eclipse and a magenta GD marker at greatest duration[2]
- The predictions "DO NOT include the effects of mountains and valleys along the edge of the Moon"; limb corrections may shift the path limits north or south by ~1-3 km and change durations by ~1-3 seconds, and more detailed predictions "are normally posted 12-18 months before each eclipse"[1][2]

NASA's[2][3] eclipse catalogue gives the instant of greatest eclipse as 21:06:12 UT on 2031-11-14 (21:07:30 TD, the two separated by delta-T), from Saros series 143. 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.
