Total Solar Eclipse Crosses Angola
- A total solar eclipse on 2046 Aug 02, catalogued by NASA/GSFC as sequence 09610, relative number -18, of Saros series 146[1][2][3]
- Greatest Eclipse falls at 10:19:43.5 UT at 12°43.7'S 015°10.7'E, with the Sun 57.6° up, a path 206.0 km wide and a central duration of 04m51.4s[1]
- Greatest Duration is nearly four minutes earlier at 10:15:55 UT at 12°00'S 014°08'E, path width 207.2 km, central duration 04m51.6s, the figure the Google-map page also gives[1][2]
- The umbral path’s central line runs from 10°37.2'S 037°43.1'W at the opening limits (138 km wide, 02m12.7s) to 50°19.4'S 071°58.4'E at the closing limits (142 km, 02m16.3s), with the Sun on the horizon at both ends and a Moon/Sun diameter ratio of 1.037-1.038 there[1]
- The Saros 146 catalog gives the same instant in Terrestrial Dynamical Time as 2046 Aug 02 10:21:13 TD with ΔT = 90 s, gamma -0.5350, magnitude 1.0531, path width 206 km and central duration 04m51s — matching the path page’s 206.0 km and 04m51.4s[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 = 89.1 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 146 runs 1352.26 years over 76 solar eclipses, from a partial on 1541 Sep 19 to a partial on 2893 Dec 29, with only 13 total; this eclipse follows 2028 Jul 22 (05m10s) and precedes 2064 Aug 12 (04m28s) as the series’ totals 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 10:19:43 UT on 2046-08-02 (10:21:13 TD, the two separated by delta-T), from Saros series 146. 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.
