Penumbral lunar eclipse, 20 Feb 2027

The Moon passes only through the Earth’s faint outer shadow: it dims, and a dimming this slight is easy to miss. Greatest eclipse is on Sat 20 Feb 2027 at 23:12 UTC.

• Greatest eclipse Sat 20 Feb 2027, 23:12 UTC The Moon overhead at 9.8°N 14.7°E
• Magnitude -0.059 Umbral; penumbral 0.925
• Longest Penumbral 4h01m The same from everywhere the Moon is up

City by city

An eclipse of the Moon is the same sight from everywhere the Moon is up. The biggest cities on our list that see all of it, spread round that side of the world, the Moon highest first, then some that see part. Every time is the city’s own clock.

The eclipse, contact by contact

In the outer shadow for 4h01m.

Latitude by latitude

Along each latitude, the longitudes with the Moon above the horizon for the whole eclipse, and those with it up at the greatest moment. An eclipse of the Moon looks the same from everywhere it is up.

How we worked it out: the Moon’s and the Sun’s places are Meeus’s solar and lunar theories, the ones the map draws. The Earth’s shadow is sized by Danjon’s rule, as NASA’s catalogue has it, and each contact is the instant the Moon’s edge crosses the shadow’s, found to the second. Each latitude is walked 1° of longitude at a time, the Moon’s altitude asked every 15 minutes. The tests hold these to NASA’s Five Millennium Canon of eclipses: instants within a few minutes, magnitudes within a few thousandths, the phases within two minutes.

• J. Meeus, Astronomical Algorithms, ch. 25 (the Sun) and ch. 47 (the Moon), as the map draws them
• Danjon’s rule for the Earth’s shadow, as NASA’s lunar eclipse catalogue applies it (NASA/TP-2009-214172, §1.3)
