Annular Solar Eclipse Crosses Peru
- An annular solar eclipse on 2034 Sep 12, its antumbral shadow path computed by Fred Espenak for NASA's Goddard Space Flight Center[1][2]
- Greatest eclipse falls at 16:18:07.5 UT at 18°14.5'S, 072°36.4'W on the Peru-Chile coast, with the Sun 66.7° up, a path 102.1 km wide and a central-line duration of 02m57.7s[1]
- Greatest duration comes eleven minutes later and further south-east, at 16:29:24 UT at 20°04'S, 069°44'W, where the path is 101.7 km wide and annularity lasts 02m57.8s[1]; the Google map page gives the same figure, "In this case, the Greatest Duration is 02m57.8s"[2]
- The saros catalogue lists the same eclipse as 2034 Sep 12 at 16:19:28 TD (Terrestrial Dynamical Time, against the path table's Universal Time) at 18.2°S 72.6°W, path width 102 km and central duration 02m58s[3]
- The path table gives 105 timed rows at 120-second intervals from 14:34 UT to 18:02 UT, plus opening and closing "Limits" rows, in WGS 84 coordinates[1]
- The central line enters at 14:34 UT near 05°29.3'S, 123°42.0'W in the eastern Pacific and leaves at 18:02 UT near 40°03.9'S, 012°20.5'W in the South Atlantic; the outer limit rows run from 05°46.8'S, 128°54.2'W to 40°42.4'S, 005°00.7'W[1]
- The path is narrowest near greatest eclipse (about 102 km) and widens to 156-162 km at the limit rows, where annularity shortens to about 02m38-02m43s[1]
- The eclipse is member 05 of Saros 135 (sequence number 09584), with gamma -0.3936 and eclipse magnitude 0.9736[3]
- Saros 135 runs 1262.11 years from a partial eclipse on 1331 Jul 05 to a partial eclipse on 2593 Aug 17, occurs at the Moon's ascending node and holds 71 eclipses in the sequence 10P 45A 2H 6T 8P - 45 of them annular; its longest annular was 1601 Dec 24 at 10m14s[3]
- Predictions use the VSOP87/ELP2000-85 solar and lunar ephemerides with ΔT = 79.9 seconds[1][2]; the catalogue row carries ΔT = 81 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 16:18:07 UT on 2034-09-12 (16:19:27 TD, the two separated by delta-T), from Saros series 135. 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.
