Annular Solar Eclipse Crosses Mongolia
- An annular solar eclipse on 2041 Oct 25, its antumbral shadow path computed by Fred Espenak for NASA's Goddard Space Flight Center[1][2]
- Greatest eclipse falls at 01:34:55.9 UT at 09°56.1'N, 162°51.5'E in the western Pacific - well beyond the Mongolian start of the track - with the Sun 65.5° up, a path 213.1 km wide and a central-line duration of 06m07.1s[1]
- Greatest duration comes about sixteen minutes later, at 01:50:30 UT at 06°43'N, 166°03'E, where the path is wider at 218.3 km and annularity lasts 06m08.4s[1]; the Google map page repeats the figure, "In this case, the Greatest Duration is 06m08.4s"[2]
- The saros catalogue lists the same eclipse as 2041 Oct 25 at 01:36:22 TD (Terrestrial Dynamical Time, against the path table's Universal Time) at 9.9°N 162.9°E, path width 213 km and central duration 06m07s[3]
- The path table gives 106 timed rows at 120-second intervals from 23:50 UT to 03:20 UT, plus opening and closing "Limits" rows, in WGS 84 coordinates[1]
- The central line enters at 23:50 UT near 47°06.6'N, 110°40.2'E in Mongolia and leaves at 03:20 UT near 02°36.1'S, 149°33.1'W in the central Pacific; the outer limit rows run from 49°02.9'N, 103°02.2'E to 01°28.7'S, 143°50.4'W[1]
- At the ends of the track the path is wider (257-267 km) and annularity shorter (about 04m43-04m53s) than at greatest eclipse[1]
- The eclipse is member 07 of Saros 134 (sequence number 09600), with gamma 0.4133 and eclipse magnitude 0.9467[3]
- Saros 134 runs 1262.11 years from a partial eclipse on 1248 Jun 22 to a partial eclipse on 2510 Aug 06, occurs at the Moon's descending node and holds 71 eclipses in the sequence 10P 8T 16H 30A 7P; its longest annular is 2168 Jan 10 at 10m55s[3]
- Predictions use the VSOP87/ELP2000-85 solar and lunar ephemerides with ΔT = 85.2 seconds[1][2]; the catalogue row carries ΔT = 86 s[3]
- Annularity is visible only inside the central 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 01:34:55 UT on 2041-10-25 (01:36:21 TD, the two separated by delta-T), from Saros series 134. 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.
