Annular Solar Eclipse Crosses Brazil
- Greatest eclipse of the Annular Solar Eclipse of 2028 Jan 26 falls at 15:07:46.5 UT at 02°57.5'N 051°33.7'W, with the Sun 67.0° high, a path 323.0 km wide and a central duration of 10m27.1s[1]
- Annularity is longest not at greatest eclipse but at the point of Greatest Duration, 14:53:08 UT at 00°48'N 054°39'W, where the path is 328.7 km wide and the central duration reaches 10m30.6s[1][3]
- The path of annularity crosses Ecuador, Peru, Brazil, Suriname, Spain and Portugal, while the partial eclipse is visible from eastern North America, Central and South America, western Europe and northwestern Africa[2]
- The eclipse belongs to Saros series 141, with an eclipse magnitude of 0.9208 (0.921 in the decade table), gamma 0.3901 and a path 323 km wide; both catalogues give greatest eclipse in Terrestrial Dynamical Time as 15:08:59[4] and 15:08:58[2], which is the same instant as the source's 15:07:46.5 UT given ΔT = 71.9 seconds[1][2][4]
- The source page tabulates the Moon's antumbral shadow at 120-second intervals in WGS 84 coordinates - 109 timed rows from 13:20 UT to 16:56 UT plus opening and closing "Limits" rows - giving northern and southern limits, the central line, the Moon/Sun diameter ratio, the Sun's altitude and azimuth, path width and central-line duration[1]
- Saros 141 runs 1244.08 years across 70 eclipses (41 annular, 29 partial, sequence "7P 41A 22P"), from a partial eclipse on 1613 May 19 to a partial eclipse on 2857 Jun 13, all at the Moon's ascending node; its longest annular eclipse is 1955 Dec 14 at 12m09s[4]
- Predictions were generated using the VSOP87/ELP2000-85 solar and lunar ephemerides with ΔT = 71.9 seconds and "DO NOT include the effects of mountains and valleys along the edge of the Moon"; lunar limb corrections may shift the path limits by ~1-3 kilometers and change the duration by ~1-3 seconds, and more detailed predictions "are normally posted 12-18 months before each eclipse"[1][3]
- All the calculations are by Fred Espenak of NASA's Goddard Space Flight Center, who "assumes full responsibility for their accuracy"[1][2][3][4]

NASA's[2][3][4] eclipse catalogue gives the instant of greatest eclipse as 15:07:46 UT on 2028-01-26 (15:08:58 TD, the two separated by delta-T), from Saros series 141. 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.
