Total Solar Eclipse Crosses the Bahamas
- A total solar eclipse on 2045 Aug 12, catalogued by NASA/GSFC as sequence 09608, relative number 3, of Saros series 136[1][2][3]
- Greatest Eclipse falls at 17:41:10.3 UT at 25°54.9'N 078°32.1'W, with the Sun 77.6° up, a path 255.6 km wide and a central duration of 06m05.7s[1]
- Greatest Duration is a separate, earlier point at 17:35:22 UT at 27°20'N 080°21'W, path width 254.8 km, central duration 06m06.2s; the Google-map page repeats it as ‘In this case, the Greatest Duration is 06m06.2s’[1][2]
- The umbral shadow is tabulated at 120-second intervals across 100 timed rows from 16:02 UT to 19:20 UT, the central line running from 35°08.0'N 159°37.0'W at the opening limits to 11°35.5'S 022°13.4'W at the closing limits[1]
- At the path’s ends the eclipse is much shorter — 03m01.5s over a 204 km path at the opening limits and 03m01.4s over 204 km at the closing limits — against 06m05.7s at greatest eclipse[1]
- The Saros 136 catalog gives the same instant in Terrestrial Dynamical Time as 2045 Aug 12 17:42:39 TD with ΔT = 89 s, gamma 0.2116, magnitude 1.0774, path width 256 km and central duration 06m06s — rounded against the path page’s 255.6 km and 06m05.7s at greatest eclipse[1][3]
- Totality can only be seen between the blue northern and southern path limits and is longest on the red central line; yellow lines mark maximum eclipse at 10-minute intervals[2]
- Predictions use the VSOP87/ELP2000-85 solar and lunar ephemerides with ΔT = 88.3 seconds, and exclude the lunar limb profile, whose corrections ‘may shift the limits of the eclipse path north or south by ~1-3 kilometers, and change the eclipse duration by ~1-3 seconds’[1][2]
- Saros 136 runs 1262.11 years over 71 solar eclipses, 44 of them total, and is the series that produced the 07m08s eclipse of 1955 Jun 20, its longest; this one follows 2027 Aug 02 (06m23s) and precedes 2063 Aug 24 (05m49s) as the series’ durations shorten[3]
- All calculations are by Fred Espenak, NASA’s GSFC, who ‘assumes full responsibility for their accuracy’[1][2][3]

NASA's[2][3] eclipse catalogue gives the instant of greatest eclipse as 17:41:10 UT on 2045-08-12 (17:42:39 TD, the two separated by delta-T), from Saros series 136. 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.
