Annular Solar Eclipse Crosses Russia
- An annular solar eclipse on 2030 Jun 01, its antumbral shadow path computed by Fred Espenak for NASA's Goddard Space Flight Center[1][2]
- Greatest eclipse falls at 06:27:55.6 UT at 56°31.5'N, 080°04.5'E in Russia, with the Sun 55.5° up, a path 249.6 km wide and a central-line duration of 05m20.8s[1]
- Greatest duration is only 43 seconds later and barely east of it, at 06:28:38 UT at 56°33'N, 080°31'E, with the same 249.6 km width and the same 05m20.8s[1]; the Google map page repeats the figure, "In this case, the Greatest Duration is 05m20.8s"[2]
- The saros catalogue lists the same eclipse as 2030 Jun 01 at 06:29:13 TD (Terrestrial Dynamical Time, against the path table's Universal Time) at 56.5°N 80.1°E, path width 250 km and central duration 05m21s[3]
- The path table gives 98 timed rows at 120-second intervals from 04:50 UT to 08:04 UT, plus opening and closing "Limits" rows, in WGS 84 coordinates[1]
- The central line enters at 04:50 UT near 29°42.6'N, 004°23.2'E in Algeria and leaves at 08:04 UT near 37°52.6'N, 154°07.2'E in the north-west Pacific beyond Japan; the outer limit rows run from 29°26.4'N, 003°44.7'E to 33°41.6'N, 163°41.5'E[1]
- At the ends of the track the path is much wider and annularity shorter - about 344-345 km and 04m12-04m13s at the limit rows - against 249.6 km and 05m20.8s at greatest eclipse[1]
- The eclipse is member 16 of Saros 128 (sequence number 09575), with gamma 0.5626 and eclipse magnitude 0.9443[3]
- Saros 128 runs 1298.17 years from a partial eclipse on 0984 Aug 29 to a partial eclipse on 2282 Nov 01, occurs at the Moon's descending node and holds 73 eclipses in the sequence 24P 4T 4H 32A 9P; its longest annular was 1832 Feb 01 at 08m35s, so this one is well short of the series maximum[3]
- Predictions use the VSOP87/ELP2000-85 solar and lunar ephemerides with ΔT = 76.9 seconds[1][2]; the catalogue row carries ΔT = 78 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 06:27:55 UT on 2030-06-01 (06:29:13 TD, the two separated by delta-T), from Saros series 128. 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.
