Deep Partial Lunar Eclipse August 28, 2026: 96% Sturgeon Moon

The deep partial lunar eclipse August 28 2026 is a spectacular astronomical event that will turn the Sturgeon Moon up to 96% copper-red. Occurring on the night of August 27 into early August 28 (UTC), this deep partial eclipse is perfectly positioned for observers across North America, South America, Europe, and Africa.

This comprehensive guide covers exact UTC, ET, and BST contact times, global visibility maps, the official live stream schedule, and a dedicated breakdown of the Chandra Grahan 2026 status for skywatchers in India.

What Makes the August 2026 Lunar Eclipse So Rare

This striking celestial event officially closes the dramatic 2026 eclipse season, arriving exactly two weeks after the highly anticipated total solar eclipse of August 12, 2026. According to the NASA eclipse catalogue and IMCCE/Espenak data, this eclipse belongs to Saros series 138 (member 30 of 83). It occurs at the Moon's ascending node with a gamma of -0.4694, plunging the lunar disc deep into the darkest part of Earth's shadow. The umbral partial phase lasts an impressive 3 hours and 18 minutes, while the full penumbra-to-penumbra event spans 5 hours and 38 minutes.

Key astronomical facts and visual distinctions of this deep partial lunar eclipse include:

• 93% vs 96% Coverage – The umbral magnitude is 0.9319, meaning 93.2% of the lunar diameter is covered. However, approximately 96.2% of the Moon's visible disc area falls inside the umbra, creating near-totality conditions.
• Constellation Aquarius – The eclipsed Moon will be positioned against the faint background stars of the constellation Aquarius, providing a stunning backdrop for astrophotographers.
• Not a True Blood Moon – While frequently searched as the blood moon August 2026, a brilliant white sliver remains on the northern limb. We state this honestly: it is not a total eclipse, but the color contrast makes it arguably more beautiful.
• 100% Safe to View – Absolutely no eclipse glasses or solar filters are needed. Unlike the August 12 solar eclipse, this lunar event is completely safe for the naked eye and binoculars.

The visual contrast between the deep copper-red southern portion of the Moon and the brilliant white sliver on the northern limb will be breathtaking. This is the deepest and most visually striking lunar eclipse anywhere on Earth until the total lunar eclipse of December 31, 2028 - January 1, 2029. The Full Moon instant occurs at 04:18 UTC on August 28, just five minutes after greatest eclipse, giving us a 100% full moon that is almost entirely obscured by Earth's shadow.

Exact Timings of the Partial Lunar Eclipse August 28 2026

Understanding the contact times is crucial for planning your viewing session. The event begins when the Moon enters Earth's faint outer shadow (P1). The real show starts at U1, when the Moon enters the dark inner umbra. The moment of greatest eclipse is when the maximum amount of the lunar disc is covered. The umbral phase ends at U4, and the event concludes at P4 when the Moon leaves the penumbra.

Below is the comprehensive timing chart for the deep partial lunar eclipse times across global time zones:

Where Will the Eclipse Be Visible? (Global Map Breakdown)

The entire eclipse sequence is perfectly placed for observers in eastern and central North America, Central America, and South America, where the event occurs high in the sky during the middle of the night. Observers in western North America (PDT/MDT) will see the eclipse already underway at moonrise, so checking local moonrise times is essential. It is also visible across Greenland, Iceland, Scandinavia, western and central Europe, Africa, the Middle East, the eastern Pacific, and Antarctica.

Regions with no visibility: Unfortunately, this eclipse will not be visible in India, South and East Asia, Australia, New Zealand, Japan, or China, as the event occurs during their daytime hours when the Moon is below the horizon.

For observers in the UK (BST) and western Europe (CEST), the maximum eclipse occurs near 5:13 AM and 6:13 AM respectively, low in the west-southwest during brightening dawn twilight. The Moon sets before the partial phase completes, meaning an unobstructed south-western horizon is absolutely essential to catch the climax of the event.

Is the Lunar Eclipse of August 28, 2026 Visible in India?

No. The eclipse occurs during Indian daylight hours, with the greatest eclipse peaking at 09:42 AM IST on August 28. Because a lunar eclipse is only visible from the night half of Earth facing the Moon, a lunar eclipse 2026 India sighting is astronomically impossible. The Moon will be completely below the horizon across the entire Indian subcontinent during all phases of the eclipse.

Chandra Grahan August 2026 India Date Time & Sutak Kaal

Many observers search for the Chandra Grahan 2026 to observe traditional practices. However, in traditional Indian astronomical practice, sutak kaal is generally observed only for an eclipse that is visible from the location. Since this eclipse is not visible anywhere in India, sutak does not apply. For Indian residents, the night of August 27-28 is treated as an ordinary, beautiful Full Moon night.

What Indian skywatchers can explore instead in late August 2026:

• Lunar Eclipse Live Stream 2026 – Watch the event online via official observatory feeds between 06:53 AM and 12:32 PM IST on the morning of August 28.
• ISRO Celebrations – Participate in the National Space Day 2026 ISRO events happening throughout August.
• Meteor Spotting – Look up during the dark hours to catch late stragglers from the Perseid meteor shower 2026.

Why the Sturgeon Moon? The Story Behind August's Full Moon Name

The Sturgeon Moon 2026 derives its name from the Algonquin and Great Lakes indigenous tribes of North America. They noted that massive lake sturgeon—a prehistoric-looking fish that can live up to 150 years—were most readily caught during this late-summer month. Historically, this full moon is also known as the Corn Moon, Grain Moon, or Red Moon, names that reflect the agricultural harvest and the reddish hue the moon often takes on when low in the hazy summer sky.

How to Watch Safely and Photograph the 96% Eclipsed Moon

Viewing this event requires only your naked eyes, though a pair of 10x50 binoculars will beautifully reveal the advancing umbra and the rugged craters along the terminator line. To photograph it, use a 200-600 mm lens mounted on a sturdy tripod. Start near the Looney-11 rule for the bright northern limb, then bracket your exposures by 3-5 stops (using ISO 400-1600) as the dark umbra advances. Use manual focus on the terminator edge and a 2-second timer or remote shutter release to prevent camera shake. No solar filters are needed. You can even predict the copper-red brightness of the umbra using the Danjon scale L-value during maximum eclipse.

Live Stream: Watch the Eclipse Online & What's Next

If you are clouded out or located in a non-visible region like Asia or Australia, you can still experience the magic. Tune into the official free live streams provided by timeanddate.com, the Virtual Telescope Project, or various NASA observatory feeds. The next deep partial lunar eclipse will occur in February 2027, followed by the highly anticipated total lunar eclipse on December 31, 2028, which will ring in the New Year with a spectacular true Blood Moon.
