Annular Solar Eclipse Crosses the midwestern United States
- An annular solar eclipse on 2048 Jun 11, catalogued by NASA/GSFC as sequence 09615, relative number 17, of Saros series 128[1][2][3]
- Greatest Eclipse falls at 12:57:21.5 UT at 63°41.3'N 011°30.5'W, with the Sun 49.4° up, a path 271.5 km wide and a central duration of 04m58.3s[1]
- Greatest Duration is 85 seconds earlier at 12:55:56 UT at 63°44'N 012°42'W, with the same 271.5 km width and the same 04m58.3s duration, which the Google-map page also states[1][2]
- The antumbral shadow is tabulated at 120-second intervals from 11:28 UT to 14:26 UT, the central line running from 38°22.7'N 101°35.2'W at the opening limits to 34°56.1'N 070°25.6'E at the closing limits[1]
- At the path’s ends the Sun is on the horizon and the path is much wider but annularity shorter — 376 km and 04m04.6s at the start, 375 km and 04m04.0s at the end — against 271.5 km and 04m58.3s at greatest eclipse[1]
- The Saros 128 catalog gives the same instant in Terrestrial Dynamical Time as 2048 Jun 11 12:58:53 TD with ΔT = 92 s, gamma 0.6468, magnitude 0.9441, path width 272 km and central duration 04m58s — rounded against the path page’s 271.5 km[1][3]
- Annularity 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 = 90.7 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 128 runs 1298.17 years over 73 solar eclipses, from a partial on 0984 Aug 29 to a partial on 2282 Nov 01; 32 are annular against only 4 total, and this eclipse follows 2030 Jun 01 (05m21s) and precedes 2066 Jun 22 (04m40s) as its 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 12:57:21 UT on 2048-06-11 (12:58:52 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.
