For skywatchers across much of the United States, the early hours of that Tuesday promise a rare celestial show: a total lunar eclipse, when the moon passes fully into Earth’s shadow and turns a deep, rusty red. With good weather, millions from Hawaii to the Great Plains will be able to watch the so‑called “blood moon” climb, fade and blush before sunrise.
What is happening during the March 3 blood moon?
The event is a total lunar eclipse, taking place in the early morning of 3 March 2026, centred over the Pacific side of Earth. During a total lunar eclipse, the sun, Earth and moon line up almost perfectly. Earth moves between the sun and the moon, and our planet’s shadow sweeps across the lunar surface.
This eclipse coincides with March’s full “Worm Moon” — the traditional name for the full moon that appears as soils start to thaw in late winter.
The moon will be completely inside Earth’s dark central shadow for 58 minutes, giving the red “blood moon” its starring role.
Rather than vanishing, the moon will glow dim red or orange. Sunlight skims through Earth’s atmosphere, which scatters away blue light and bends the remaining red light into our planet’s shadow. That tinted light softly illuminates the lunar surface, creating the blood moon effect that fascinates both casual observers and seasoned astronomers.
When to watch from the US: key eclipse times
The full eclipse unfolds over 5 hours and 39 minutes, including the subtle penumbral stages when the moon first brushes Earth’s outer shadow. The most dramatic portion — totality — lasts just under an hour.
Totality times across US time zones
Here’s when the total phase of the eclipse occurs in major US time zones on 3 March 2026:
- Eastern Standard Time (EST): 6:04–7:02 a.m. (moon will be setting during totality)
- Central Standard Time (CST): 5:04–6:02 a.m.
- Mountain Standard Time (MST): 4:04–5:02 a.m.
- Pacific Standard Time (PST): 3:04–4:02 a.m.
- Alaska Standard Time (AKST): 2:04–3:02 a.m.
- Hawaii Standard Time (HST): 1:04–2:02 a.m.
Anyone west of the Mississippi River has a strong chance of seeing the whole total phase, provided skies stay clear.
Viewers in the eastern US and eastern Canada, including New York, Boston and Toronto, will be watching the moon sink toward the horizon as totality unfolds, which can create striking photo opportunities but limits observing time.

Who gets the best view globally?
The night side of Earth during the eclipse is centred over the Pacific Ocean. That favours:
- Hawaii
- Kiribati
- Samoa, Tonga and the Cook Islands
- Australia and New Zealand
- Parts of East Asia
- Western North America
According to estimates based on visibility maps, about 176 million people could see all phases of the eclipse, including both partial and total stages, skies permitting.
Where in the US you’ll see the full show
Across North America, the further west you are, the better your odds of catching the entire progression from first shadow to last.
- Best positioned: West Coast states, the US Southwest, northwest Mexico and Hawaii, with the moon higher in the sky during totality.
- Good visibility: Central US states, where the moon remains above the horizon for all of totality.
- Challenging views: Eastern US and eastern Canada, where totality overlaps with moonset and dawn brightening the sky.
Weather plays a huge role. Statistically, clear, dry air in the Southwest and over parts of the Pacific tends to offer the sharpest views. Cloud cover over the Midwest and Northeast in late winter can be stubborn, so having a backup plan — such as driving to clearer skies or tuning into observatory webcasts — is wise.
How the eclipse will unfold in the sky
Although many people focus on the red phase, the whole timeline is worth watching. The eclipse passes through several distinct stages:
| Stage | What you’ll see |
|---|---|
| Penumbral eclipse | Moon enters Earth’s outer shadow. A faint shading appears on one edge, often hard to detect at first. |
| Partial eclipse | A dark, curved “bite” from Earth’s umbral shadow moves across the lunar disk. Contrast is obvious to the naked eye. |
| Totality begins | The last bright sliver disappears and the moon starts glowing red or orange against a darkened sky. |
| Mid-totality | Deepest colour and dimmest brightness. Background stars become visible near the moon. |
| Totality ends | White sunlight returns to one limb of the moon as it leaves the umbra. |
| Partial and penumbral exit | Shadow slowly slides off; moon returns to its normal full brightness. |
Even a modest pair of binoculars will make the curved edge of Earth’s shadow and the craters in red light stand out.
Why the blood moon looks red — and why the colour changes
The intensity of the red hue depends on Earth’s atmosphere at the time. When our atmosphere is relatively clear, the moon may appear bright copper or orange. After major volcanic eruptions or when global pollution is high, the eclipse can look dimmer, even brownish or brick red.
Light from the sun must pass through a thick ring of air around Earth’s limb. Shorter blue wavelengths scatter away in all directions, which is the same reason the daytime sky looks blue. Redder wavelengths bend through the air and into Earth’s shadow, painting the moon with that warm tint.
In effect, the moon is being lit by every sunrise and sunset happening around Earth’s edge at that moment.
How to watch the March 3 eclipse safely and comfortably
Unlike a solar eclipse, a lunar eclipse does not require any protective glasses. You can look at it directly with your eyes for as long as you like.
- Find a dark spot: Choose a place with a clear view toward the western sky if you’re in the eastern US, or higher elevations if you’re inland or near hills.
- Check local times: Convert the totality times to your local time zone and set an alarm at least 30–60 minutes early.
- Use simple gear: Binoculars or a small telescope reveal detail, but the eclipse is impressive even without equipment.
- Dress for the cold: Early March nights can still be bitter, especially in the northern states, so plan for winter conditions.
- Photographing: A tripod and a camera with manual settings let you capture the red moon; start with higher ISO and longer exposures during totality.
Where this eclipse fits in the lunar eclipse cycle
The March 3 event is part of an ongoing rhythm of lunar eclipses that repeat in predictable patterns. It is the first total lunar eclipse since September 2025 and marks the beginning of a relatively quiet stretch.
After March 3, skywatchers will wait until New Year’s Eve 2028 for the next total blood moon.
That 31 December 2028 eclipse is scheduled to kick off a trio of total lunar eclipses, with follow‑up events in late June and late December 2029. So for several years after 2026, partial or penumbral eclipses will dominate, making this early‑morning show something of a standout for North American observers.
Key eclipse terms worth knowing
For anyone new to eclipse watching, the jargon can feel opaque. A few terms help make sense of what you’re seeing:
- Penumbral shadow: The faint outer part of Earth’s shadow, where only part of the sun is blocked. Changes in brightness are subtle.
- Umbral shadow: The dark inner core of the shadow, where direct sunlight is fully blocked. This is where the moon turns red.
- Totality: The period when the entire visible face of the moon lies inside the umbra.
- Partial eclipse: Times when only a portion of the moon is inside the umbra.
Knowing these terms makes it easier to follow live commentary or plan your own observing schedule so you don’t miss the most dramatic phases.
Ideas to turn the eclipse into an experience
The timing of this eclipse before dawn makes it a natural fit for early risers, families with older children, or anyone willing to trade a bit of sleep for a memory. Schools or community groups might organise pre‑dawn meet‑ups in car parks, parks or observatory grounds, pairing the event with hot drinks and basic astronomy talks.
For a simple at‑home activity, some observers like to sketch the moon every 10–15 minutes as the shadow creeps across the surface. Others use a smartphone on a steady surface to record a short time‑lapse. Comparing your own notes, sketches or photos with friends in other states can highlight how the moon’s position in the sky and the local horizon change the experience across the continent.
