Events · calendar month

This month

The whole calendar month. Four lunar phases, whatever the planets are doing, and any eclipse or shower that falls inside it.

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.

28 events

  • Last Quarter Moon

    Computed

    Half the disc is lit again, on the other side. The Moon rises around midnight, so the evening sky is dark.

    How exact: Within about forty minutes of NASA’s published instant — measured, not asserted: the build checks every phase of 2026–2028 against NASA’s own table and the largest disagreement is thirty-eight minutes. The limit is the truncated lunar theory the whole platform uses, not the search.

    Where this date comes from

    Derived on this platform from published position series. The algorithm and its version are recorded, and the stated uncertainty is the real one.

    Method: The instant the Moon's geocentric ecliptic longitude exceeds the Sun's by the phase angle, both referred to the mean equinox of date, located by bisection on the low-precision lunar and solar series. (lunar-phase-elongation-crossing, version 1.0.0)

    Uncertainty: Within about forty minutes of NASA’s published instant — measured, not asserted: the build checks every phase of 2026–2028 against NASA’s own table and the largest disagreement is thirty-eight minutes. The limit is the truncated lunar theory the whole platform uses, not the search.

    Where it applies: The instant is the same everywhere; only the local clock time and whether the Moon is above your horizon differ.

  • Moon at perigee

    Computed

    The Moon reaches the closest point of its orbit this month, appearing marginally larger than average — a difference of a few per cent in diameter, not something the eye registers without a side-by-side comparison.

    How exact: The date is reliable; the hour is not. The distance curve is almost flat for a day either side, and unlike the phases and the equinoxes this one is not checked against an external table — no comparable published series is connected — so treat the time as indicative.

    Distance
    about 368,300 km, centre to centre
    Where this date comes from

    Derived on this platform from published position series. The algorithm and its version are recorded, and the stated uncertainty is the real one.

    Method: A turning point of the Earth–Moon distance from the low-precision lunar series, located by bisecting the derivative after a coarse scan. (lunar-apsis-distance-extremum, version 1.0.0)

    Uncertainty: The date is reliable; the hour is not. The distance curve is almost flat for a day either side, and unlike the phases and the equinoxes this one is not checked against an external table — no comparable published series is connected — so treat the time as indicative.

    Where it applies: A property of the orbit, the same for every observer.

  • New Moon

    Computed

    The Moon passes between Earth and the Sun and its near side is unlit. The darkest skies of the month fall around this date.

    How exact: Within about forty minutes of NASA’s published instant — measured, not asserted: the build checks every phase of 2026–2028 against NASA’s own table and the largest disagreement is thirty-eight minutes. The limit is the truncated lunar theory the whole platform uses, not the search.

  • September equinox

    Computed

    The Sun crosses the celestial equator going south, beginning the northern autumn and the southern spring.

    How exact: Within about fifteen minutes of the US Naval Observatory’s published instant — measured on every build against their figures for 2026–2028, where the largest disagreement is twelve minutes.

    Where this date comes from

    Derived on this platform from published position series. The algorithm and its version are recorded, and the stated uncertainty is the real one.

    Method: The instant the Sun's apparent geocentric ecliptic longitude, referred to the mean equinox of date, reaches the quadrant boundary — which is the definition of the equinoxes and solstices. (solar-longitude-crossing, version 1.0.0)

    Uncertainty: Within about fifteen minutes of the US Naval Observatory’s published instant — measured on every build against their figures for 2026–2028, where the largest disagreement is twelve minutes.

    Where it applies: A single instant for the whole Earth. The calendar date it falls on depends on your time zone.

  • Neptune at opposition

    Computed

    Neptune lies opposite the Sun, rising as the Sun sets and visible all night. It is near its closest to Earth for this apparition and at its brightest.

    How exact: Within a few hours. The platform’s planetary positions are checked on every build against JPL Horizons and agree to under five arcminutes, which at the rate a planet separates from the Sun is a few hours in the date. Opposition is a broad event in any case: the planet is barely changed in brightness or size for a week either side.

    Distance from Earth
    28.875 au
    Approximate magnitude
    7.8
    Where this date comes from

    Derived on this platform from published position series. The algorithm and its version are recorded, and the stated uncertainty is the real one.

    Method: The instant the planet's geocentric ecliptic longitude differs from the Sun's by exactly 180°, both referred to the mean equinox of date, from the JPL approximate planetary elements. (planet-solar-longitude-opposition, version 1.0.0)

    Uncertainty: Within a few hours. The platform’s planetary positions are checked on every build against JPL Horizons and agree to under five arcminutes, which at the rate a planet separates from the Sun is a few hours in the date. Opposition is a broad event in any case: the planet is barely changed in brightness or size for a week either side.

    Where it applies: Observable from anywhere the planet rises, which for these planets is most of the inhabited world.

  • Full Moon

    Computed

    The Moon is opposite the Sun and fully lit, above the horizon all night. Faint objects are washed out for several nights either side.

    How exact: Within about forty minutes of NASA’s published instant — measured, not asserted: the build checks every phase of 2026–2028 against NASA’s own table and the largest disagreement is thirty-eight minutes. The limit is the truncated lunar theory the whole platform uses, not the search.

    Where this date comes from

    Derived on this platform from published position series. The algorithm and its version are recorded, and the stated uncertainty is the real one.

    Method: The instant the Moon's geocentric ecliptic longitude exceeds the Sun's by the phase angle, both referred to the mean equinox of date, located by bisection on the low-precision lunar and solar series. (lunar-phase-elongation-crossing, version 1.0.0)

    Uncertainty: Within about forty minutes of NASA’s published instant — measured, not asserted: the build checks every phase of 2026–2028 against NASA’s own table and the largest disagreement is thirty-eight minutes.

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.

Source file: https://ll.thespacedevs.com/2.2.0/launch/upcoming/?limit=40&mode=list

Upcoming orbital launches from Launch Library 2, fetched from https://ll.thespacedevs.com/2.2.0/launch/upcoming/?limit=40&mode=list. The provider allows fifteen requests an hour. Thirty minutes puts AsteriaStar at two, leaving the rest of the allowance for everyone else, and a launch schedule does not change meaningfully inside half an hour — when it does change, it changes by days.

Intentions, not appointments. Every date is a No Earlier Than value whose precision the provider states explicitly, from the second down to the year, and which moves without notice. The feed is an aggregation of operator announcements maintained by volunteers, not a schedule published by any agency.
