Partial Lunar Eclipse of 2026-08-28
Deep partial lunar eclipse — 93% of the Moon's diameter passes through Earth's umbra. Best from the Americas and west Africa.
Deepest partial lunar eclipse of 2026; 93% obscuration leaves only a thin crescent of the Moon outside Earth's umbra.

Frequently asked questions
Where will the partial lunar eclipse of 2026-08-28 be visible?
Deep partial lunar eclipse — 93% of the Moon's diameter passes through Earth's umbra. Best from the Americas and west Africa. Partial phases are visible from United States, Mexico, Brazil, Argentina, Spain, Portugal, and 2 more.
What time will the 2026-08-28 partial lunar eclipse reach greatest eclipse?
Greatest eclipse occurs at 04:14 UTC on 2026-08-28 (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 2026-08-28 eclipse?
The full umbral duration is not published in the catalog for this event.
When is the next lunar eclipse after the 2026-08-28 partial lunar eclipse?
The next lunar eclipse after 2026-08-28 is the total lunar eclipse on 2028-12-31 (16:53 UTC). It will be visible from europe, africa, middle east, asia, western australia.
Do I need any special equipment to watch the 2026-08-28 partial 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 2026-08-28 partial lunar eclipse?
Partial Lunar Eclipse of 2026-08-28 is member 20 of 71 of NASA Saros series 147. 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.

What the partial 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 partial lunar eclipse with WorldClockTools local-clock pages.
Saros series context
Partial Lunar Eclipse 2026-08-28 is member 20 of 71 of NASA Saros series 147. 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 0.930 (Moon diameter eclipsed). Obscuration figures are not in the current catalog cut for this event.
Duration on the central line
Umbral duration is not published in the catalog cut for this event.
Path and visibility footprint
Visible from united states, mexico, brazil, argentina, spain, and portugal, and 2 more.
City cross-references
Cross-referenced cities in the WorldClockTools catalog that fall in the path or partial band: Mexico City, Lisbon, Madrid, and Buenos Aires. 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 1.0123 — 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
Deepest partial lunar eclipse of 2026; 93% obscuration leaves only a thin crescent of the Moon outside Earth's umbra.
Catalog handoff
Next lunar eclipse handoff: total lunar eclipse 2028 12 31. Next eclipse of any kind: annular solar eclipse 2027 02 06. The full eclipse calendar lists 14 upcoming events.
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.
