Novilune: Eclipse Atlas

Novilune is a visual almanac of new moons and solar eclipses, computed with professional-grade astronomy for any place on Earth you care to choose.

At each new moon — the moment when Sun and Moon meet in conjunction — Novilune draws the two disks at their closest approach in the sky of the place you picked, and tells you what you would actually see from there: a quiet miss, a partial eclipse, or a central one, total or annular.

THE NEXT ECLIPSES
• 6 February 2027 — annular across Chile, Argentina, Uruguay, southern Brazil and West Africa
• 2 August 2027 — total from southern Spain across Morocco, Algeria, Libya and Egypt, with more than six minutes of totality; partial over most of Europe and the Middle East
• 26 January 2028 — annular across Ecuador, Peru, Brazil and French Guiana, ending at sunset over Portugal and Spain

Type the name of your town and Novilune shows you what will happen there: the local time, the share of the Sun covered, the Sun's altitude above the horizon. Enter a city on the path of totality and see the difference with your own eyes — then open the map to see where that path runs, down to your village.

WHAT YOU GET
• A calendar of 11,900 eclipses and more than 61,000 lunations, from 2000 BC to AD 3000
• A verdict that says what YOUR PLACE saw: an eclipse that ran its whole course below the horizon is not counted as yours — the map and the animation still show you where it was visible
• An accurate diagram of Sun and Moon at maximum, with the Moon's path across the sky
• Local circumstances: magnitude, separation, altitude of the Sun, local time and Universal Time
• A five-millennium timeline and a fine year-by-year cursor
• A five-step guided tour on first launch: nothing to set up, no account
• Side-by-side comparison of two places, each at its own local maximum
• PNG export of any eclipse view
• The eclipse map: where each eclipse is visible on Earth, with the path of totality, on a built-in offline map or a detailed online map zoomable down to your village
• The eclipse animation: the Moon's shadow sweeping across the Earth, frame by frame, on a globe or a flat map; share it as a GIF
• Works fully offline: the complete ephemeris is embedded
• English, French and Spanish

SERIOUS ASTRONOMY, SIMPLY SHOWN
Novilune is not an artist's impression. Every syzygy is computed from the JPL DE441 ephemeris, with careful handling of the slow drift of Earth's rotation (ΔT), so that even ancient eclipses appear where and when they really happened. Uncertainty is shown honestly: distant dates carry a visible margin instead of false precision.

That is what makes Novilune useful far beyond the coming years: for the eclipse of Thales in 585 BC, said to have interrupted a battle between Medes and Lydians; for the Assyrian eclipse of 763 BC, the anchor of the whole chronology of the ancient Near East; or for any darkening of the Sun mentioned in an old chronicle.

FREE VERSION AND FULL VERSION
The free version covers every solar eclipse from 2000 to 2050. A single one-time purchase (no subscription, no recurring cost) unlocks the whole calendar, from 2000 BC to AD 3000, the comparison of two places, and sharing the animation as a GIF.

YOUR PRIVACY
No ads. No account. No data collected.

Whether you are an astronomy enthusiast, a teacher, a historian curious about an eclipse mentioned in an ancient chronicle, or simply wondering what the sky did over a city on the other side of the world, Novilune turns the calendar of the Sun and the Moon into something you can see.
