Advanced Eclipse Engine 2.0 is more accurate than the previous release, and the type differences against NASA's canon are gone. Calibrated against NASA's Five Millennium Canon of Solar Eclipses (years 1-2999): every reference eclipse is found, and eclipse types match the canon. All 295 hybrid eclipses in that span are found. This version adds Full Espenak: refine one event, or search at most one year, with fuller ephemerides. Cards show real phase contacts: central-phase begin and end for the Sun, penumbral and umbral contacts for the Moon, and local C1-C4 at your site. If the Sun or Moon is below the horizon, we say so. That is not the same as being outside the path. Eclipse search stays free for ±5 years around today. A wider range is in Eclipse Pro.

Advanced Eclipse Engine 2.0 — the precision ceiling we have reached. Calibrated against NASA’s Five Millennium Canon of Solar Eclipses (years 1–2999): every reference eclipse is found. Types match the canon in 99.9% of cases — 17 events differ. Median timing error is about 0.39 minutes. Median duration error is 2.7 seconds, the ceiling that replaced the earlier 10.1-second figure. Versus NASA, median gamma error is about 0.0009 Earth radii and median magnitude error about 0.0008. All 295 hybrid eclipses in that span are found.

Advanced Eclipse Engine 2.0 — a major leap to professional-grade accuracy. We rebuilt and recalibrated our physical eclipse engine against NASA’s Five Millennium Canon of Solar Eclipses (years 1–2999). Full catalog coverage: every reference eclipse found. Types match the canon in 99.9% of cases — only 17 events differ, at noise level against a multi-millennium catalog. Median timing error about 0.39 minutes; median duration error about 2.7 seconds. Versus NASA, median gamma error is about 0.0009 Earth radii and median magnitude error about 0.0008. Our hybrid detector found every hybrid eclipse across those three millennia (295/295), with the same high fidelity as total, annular, and partial types. The engine uses only physical principles and formulas — not ad-hoc heuristics: Earth–Moon–Sun geometry is modelled in a single physical framework. It is one of the few eclipse calculation libraries written strictly for iOS, running fully on-device. Local visibility is more rigorous too: topography, observer elevation, and the path band are included so results better match what you can actually see from your location. Eclipse search is free for ±5 years around today. The full historical and future range remains available with Eclipse Pro.

Performance fix: App Store builds are now archived as Release (optimized), matching local Xcode Release. Fixes time scrubber lag present in previous Debug-archived builds.
