Total Lunar Eclipse of 2029-12-20

Total lunar eclipse near the December solstice — Moon at high northern declination, well-placed for northern-hemisphere viewers.

December-solstice total lunar eclipse with the Moon at high northern declination, giving it an especially long arc through the sky for northern observers.

Frequently asked questions

Where will the total lunar eclipse of 2029-12-20 be visible?
Total lunar eclipse near the December solstice — Moon at high northern declination, well-placed for northern-hemisphere viewers. Partial phases are visible from United States, Mexico, Brazil, Argentina, United Kingdom, Spain, and 3 more.
What time will the 2029-12-20 total lunar eclipse reach greatest eclipse?
Greatest eclipse occurs at 22:43 UTC on 2029-12-20 (Coordinated Universal Time). To convert to local time for your city, the conversion uses the IANA timezone for that locale — the WorldClockTools eclipse-calendar page surfaces the conversion automatically for any of the listed cities.
How deep is the partial phase of the 2029-12-20 eclipse?
Maximum umbral phase lasts 54m (NASA).
When is the next lunar eclipse after the 2029-12-20 total lunar eclipse?
This is the last eclipse of its kind in the current upcoming-eclipse window through 2030.
Do I need any special equipment to watch the 2029-12-20 total lunar eclipse?
No — lunar eclipses are entirely safe to view with the naked eye. The Moon is illuminated by sunlight scattered through Earth's atmosphere, so even at greatest eclipse it is no brighter than a full Moon at perigee.
What is the Saros series for the 2029-12-20 total lunar eclipse?
Total Lunar Eclipse of 2029-12-20 is member 23 of 71 of NASA Saros series 144. Each Saros series produces an eclipse every 18 years 11 days, with successive members shifted roughly 120 degrees west in longitude. Saros series typically span 12 to 15 centuries and contain 70 to 80 eclipses each.

Eclipse data depth

What the total lunar eclipse entry signals

A compact read of the NASA catalog row: Saros context, magnitude / obscuration math, path geometry, and the city / country cross-references that pair total lunar eclipse with WorldClockTools local-clock pages.

Saros series context

Total Lunar Eclipse 2029-12-20 is member 23 of 71 of NASA Saros series 144. Each Saros member repeats roughly every 18 years 11 days, shifted ~120 degrees west, so adjacent members in the same series land on different continents.

Magnitude and obscuration

Magnitude is 1.117 (Moon diameter eclipsed). Obscuration figures are not in the current catalog cut for this event.

Duration on the central line

Maximum umbral duration is 54m as published by NASA.

Path and visibility footprint

Visible from united states, mexico, brazil, argentina, united kingdom, and spain, and 3 more.

City cross-references

Cross-referenced cities in the WorldClockTools catalog that fall in the path or partial band: Mexico City, Buenos Aires, Madrid, and Lisbon. Each city has its own clock page; pairing the eclipse time with the local clock gives the immediate local-time answer.

Gamma and geometry

Gamma is -0.4221 — the lateral distance of the Moon from Earth's umbral center at greatest eclipse, in Earth-radii. Lower |gamma| means a deeper, longer totality; near-zero values produce the maximum umbral duration.

What is notable

December-solstice total lunar eclipse with the Moon at high northern declination, giving it an especially long arc through the sky for northern observers.

Editorial dossier

No editorial dossier is attached; the page renders programmatic NASA-derived facts only, with no curated commentary.
Eclipse predictions are deterministic from JPL ephemerides — but local circumstances (exact path edge, sun altitude, weather) change with the kilometer. The NASA interactive map linked below gives precise local circumstances for any coordinates.
