Eclipses
Solar and lunar eclipses for the year ahead, taken from NASA's Five Millennium Catalog exactly as published — including the delta-T that turns its dynamical time into the clock on your wall.
Times are UTC throughout, because an instant is the same everywhere and a local rendering would hide which day an event actually falls on for you. Nothing here knows or asks where you are. Every computed instant carries an uncertainty, and most of those are measurements rather than estimates: every build checks the lunar phases against NASA's own published table, the equinoxes, solstices and Earth's apsides against the US Naval Observatory's, and the planetary positions the remaining events are derived from against JPL Horizons. The Moon's perigee and apogee are the one family with no external table to check against, and their cards say so.
5 events
Annular solar eclipse
Published predictionThe Moon is too far from Earth to cover the Sun completely, leaving a bright ring. There is no safe moment to look without a filter, at any point of an annular eclipse. Never look at the Sun without a filter made for the purpose. Sunglasses, exposed film and smoked glass are not filters, and neither is a camera, binocular or telescope without one fitted in front of the objective.
How exact: As published. Instants are quoted to the second in the catalogue; the conversion to UTC uses the catalogue's own ΔT, which is itself a prediction for future dates.

Where this date comes from
Taken from an authority's own published prediction. AsteriaStar reproduces it and links the document; it does not recompute it.
Uncertainty: As published. Instants are quoted to the second in the catalogue; the conversion to UTC uses the catalogue's own ΔT, which is itself a prediction for future dates.
Where it applies: Greatest eclipse occurs over 31°S, 48°W. Which places see totality, and which see only a partial eclipse, is set by the shadow path — AsteriaStar does not compute it, and NASA publishes the maps.
Penumbral lunar eclipse
Published predictionThe Moon passes only through the faint outer shadow. The effect is a subtle shading across the disc, and a shallow one is genuinely hard to notice.
How exact: As published. Instants are quoted to the second in the catalogue; the conversion to UTC uses the catalogue's own ΔT, which is itself a prediction for future dates.

Where it applies: Visible from the whole night side of Earth at the time of greatest eclipse; the Moon is overhead at the point listed below and lower in the sky the farther you are from it.

Total solar eclipse
Published predictionThe Moon covers the Sun completely along a narrow path, where the corona becomes visible. Everywhere else in the region sees a partial eclipse. Never look at the Sun without a filter made for the purpose. Sunglasses, exposed film and smoked glass are not filters, and neither is a camera, binocular or telescope without one fitted in front of the objective.

Four kinds of date
- Computed
- Derived on this platform from published position series. The algorithm and its version are recorded, and the stated uncertainty is the real one.
- Published prediction
- Taken from an authority's own published prediction. AsteriaStar reproduces it and links the document; it does not recompute it.
- Annual forecast
- Recurs every year at approximately the same point in Earth's orbit. The date shown is the expected one; the exact hour and the strength vary from year to year.
- Planned
- A date somebody intends to meet. Planned dates move, often by months. The timestamp of the last confirmation is shown so you can judge how much the date is worth.
Take this away as a calendar file: subscribe or download the next year of events, or read it as JSON from the Open Data API. Both carry the basis, the method or source, and the uncertainty for every entry.

Solar eclipses of the twenty-first century from NASA Eclipse Web Site, fetched from https://eclipse.gsfc.nasa.gov/SEcat5/SE2001-2100.html. The catalogue was computed once and published in 2007. A week is not a compromise between freshness and load — there is no freshness to trade, and re-parsing two hundred and twenty-four eclipses on every page view would be waste with no upside.
Circumstances of GREATEST eclipse only: the instant, the type, the Saros series, gamma, the magnitude, and the point on Earth the shadow axis passes closest to. It does not say what an eclipse looks like from any particular place, and neither does AsteriaStar — local circumstances need the Besselian elements, which NASA publishes separately and which are not read here.
