A Total Lunar Eclipse Will Turn the Moon Red on March 3. Here’s What You Need to Know
The third total lunar eclipse in the past year rises over the contiguous U.S. on Tuesday, March 3 — and it’s the final one with good visibility until June 25, 2029.
KEY FACTS:
- Totality runs from 6:03 a.m. to 7:02 a.m. EST — a 59-minute window for blood moon viewing and photography.
- The greatest eclipse occurs at 6:33 a.m. EST, the midpoint of totality when the Moon sits deepest in Earth’s umbra.
- Western U.S. observers get the best views, with the entire event unfolding well before sunrise in Pacific and Mountain time zones.
- No eye protection is needed — unlike a solar eclipse, a total lunar eclipse is safe for naked-eye viewing throughout.
- The next total lunar eclipse is Dec. 31, 2028, but it will be much more difficult to see in the U.S. The next one with good visibility arrives June 25, 2029.
What Is a Total Lunar Eclipse?
A total lunar eclipse occurs when Earth passes directly between the Sun and the Moon, casting its full shadow — the umbra — across the entire lunar surface.
The signature “blood moon” color results from sunlight filtering through Earth’s atmosphere. Short-wavelength colors like blue and green scatter, while longer-wavelength reds and oranges pass through and shine onto the Moon.
Earth’s shadow has two parts: the penumbra (the outer, lighter shadow producing only subtle dimming) and the umbra (the inner, darker shadow that creates the unmistakable dark bite sweeping across the lunar face).
Complete Phase-by-Phase Timeline (EST)
Penumbral Eclipse Begins — 3:43 a.m. EST
Duration: 1 hour, 6 minutes. The Moon contacts the outer part of Earth’s shadow. Dimming is subtle at first. For photographers, this is a good window to dial in exposure settings while the Moon is still near full brightness.
Partial Eclipse Begins — 4:49 a.m. EST
Duration: 1 hour, 14 minutes. The Moon contacts Earth’s umbra. More of the surface turns dark — this is when the visual drama starts, with Earth’s curved shadow creeping across the lunar face.
Totality Begins — 6:03 a.m. EST
Duration: 59 minutes. The entire Moon is covered by Earth’s deepest shadow and appears reddish. The greatest eclipse at 6:33 a.m. EST marks the midpoint — often producing the most vivid coloring.
Second Partial Eclipse — 7:02 a.m. EST
Duration: 1 hour, 15 minutes. Totality ends and the umbra gradually retreats across the lunar surface.
Second Penumbral Eclipse — 8:17 a.m. to 9:23 a.m. EST
Once this ends, the full Moon returns to full direct sunlight.
Where You Are Matters
Visibility varies significantly by location.
Eastern U.S.: Totality runs from 6:03 to 7:02 a.m. EST, meaning you’ll be racing against approaching dawn. The later phases — the second partial eclipse starting at 7:02 a.m. EST and the final penumbral phase from 8:17 to 9:23 a.m. EST — will coincide with brightening skies.
Western U.S.: Darker skies prevail during the key phases, with the entire event playing out well before sunrise in Pacific and Mountain time zones. If you have flexibility to travel or choose a western vantage point, it will make a meaningful difference for both observation and photography.
Gear Recommendations
Binoculars are the best way to view the eclipse. Look for 7x50 or 10x50 configurations.
The 7x50 offers a wide, bright field of view that’s forgiving for handheld use, while 10x50 provides slightly more magnification with the same 50mm objective lens for solid light gathering.
Either will let you resolve color gradients and shadow edge detail far better than unaided eyes.
For those photographing with telescopes or telephoto lenses, the 59-minute totality window provides solid working time to experiment with exposure bracketing and capture the subtle shift in hue between totality’s start and greatest eclipse.
What Comes Next
A partial lunar eclipse occurs on Aug. 28 for those tracking the full 2025–2026 eclipse calendar. But for total lunar eclipses visible from the U.S., March 3 is the final favorable opportunity for years.
This is the third total lunar eclipse in the past year over the contiguous U.S., following events on March 14 and Sept. 7 of 2025. Set your alarms accordingly.
BOTTOM LINE: If you want to see or photograph a total lunar eclipse from the U.S. without waiting until 2029, Tuesday morning March 3 is your last chance — set an alarm for well before 6:03 a.m. EST.
