Blood Moon Eclipse This Week: Exact Time & How to Watch
The "Almost Total" Lunar Eclipse: Your Complete Guide to Thursday Night’s Sky Show
TL;DR: On Thursday night/Friday morning, the Moon will turn a spooky red-copper color as 96% of it slips into Earth’s shadow. It’s not quite a total eclipse, but that tiny sliver of brightness makes it extra special. Peak is at 12:12 AM Friday (Boston time). Grab a blanket, hope for clear skies, and enjoy the "Blood Moon"!
What’s Happening & Why It’s Cool
Imagine Earth standing between the Sun and the Moon, casting a giant shadow into space. As the Moon orbits Earth, it sometimes walks right through that shadow. That’s a lunar eclipse.
This Thursday’s eclipse is a "deep partial" — 96% of the Moon will be covered by Earth’s dark inner shadow (the umbra). A tiny 4% sliver stays lit by direct sunlight, creating a cool "yin-yang" effect: most of the Moon glows reddish-copper like a penny, while one edge stays bright white.
Why red? Earth’s atmosphere acts like a lens, bending (refracting) sunlight around our planet. Blue light gets scattered away (why our sky is blue), but red/orange light passes through and paints the Moon. It’s literally all the world’s sunrises and sunsets projected onto the Moon at once!
Eclipse Timeline (All Times Boston / EDT)
| Phase | Time | What You’ll See |
|---|---|---|
| Penumbral begins | 9:23 PM Thu | Moon enters Earth’s faint outer shadow — barely noticeable dimming |
| Partial/umbral begins | 10:33 PM Thu | Dark "bite" appears on Moon’s edge — Earth’s dark inner shadow touches down |
| MAXIMUM ECLIPSE | 12:12 AM Fri | 96% covered — stunning red "Blood Moon" with tiny bright sliver |
| Partial/umbral ends | 1:51 AM Fri | Shadow retreats, Moon returns to normal |
| Penumbral ends | ~3:00 AM Fri | Fully done (subtle, easy to miss) |
Pro tip: The best viewing window is 11:30 PM – 12:45 AM. That’s when the red color is deepest and the contrast with the bright sliver is sharpest.
Where Can You See It?
Good news for most of the Americas! The entire eclipse (all phases) is visible from:
- All of contiguous US, Canada (except Alaska & NW Canada), Mexico, Central & South America
- Western Europe & Western Africa (Moonset during later phases)
- Alaska, Hawaii, NW Canada, Asia, Australia, most of Africa/Europe — miss some or all
The map from NASA shows visibility contours — if you’re inside the orange line, you’ll see the partial phase start.
Weather Forecast (New England Focus)
| Region | Sky Condition | Rain/Showers? |
|---|---|---|
| Eastern/Coastal NE | Partly to mostly cloudy | Low chance |
| Western NE | Increasing clouds | Scattered showers possible |
Fingers crossed! Clouds are the only thing that can ruin this. Check your local forecast Thursday afternoon. If it’s overcast, you can watch live streams (NASA, timeanddate.com, etc.).
Fun Science: The "Saros 138" Family & The "Almost Tetrad"
Saros 138 — An 18-Year Family Reunion
Eclipses run in families called Saros cycles. Every 18 years, 11 days, 8 hours, the Sun-Earth-Moon geometry almost repeats.
- Saros 138 started in 1521 and runs until 2982 (that’s 1,461 years!)
- Every lunar eclipse in this series since 1918 has been partial
- This one (96%) is the DEEPEST partial so far
- Next in line (2044): FINALLY a TOTAL eclipse!
The "Almost Tetrad" (4 eclipses in 18 months)
A tetrad = 4 total lunar eclipses in a row, ~6 months apart. Rare!
| Date | Type | Notes |
|---|---|---|
| Mar 14, 2025 | Total | First of the set |
| Sep 8, 2025 | Total | Second |
| Mar 3, 2026 | Total | Third |
| Thu/Fri (this one) | 96% Partial | Fourth — "Almost Tetrad" |
- True tetrads: Last in 2014–15, next in 2032–33
- This "almost" tetrad is special — three totals + one super-deep partial
Bonus: It’s the "Sturgeon Moon"!
The exact full moon is at 12:18 AM Friday — just 6 minutes after max eclipse. August’s full moon is traditionally called the Sturgeon Moon (named by Algonquin tribes for the great lakes sturgeon fishing season).
Fun fact from the author: "I was watching sturgeon jumping in a Maine cove this weekend — now I know why it’s called that!"
Step-by-Step: How to Watch Like a Pro
- Check the weather Thursday afternoon — if cloudy, find a live stream
- Pick a spot with a clear view south/southeast (Moon rises in SE, moves south)
- Go out by 10:30 PM — catch the partial phase starting at 10:33 PM
- Bring: Chair/blanket, warm layers, hot drink, binoculars (optional but awesome)
- Stay through 12:12 AM for the peak "Blood Moon" moment
- Watch the shadow retreat until 1:51 AM if you’re a night owl
- Take photos! Phone cameras work; try "night mode" or a tripod for best results
- Share the view — point it out to neighbors, kids, dogs
No telescope needed! Lunar eclipses are perfectly safe and spectacular with naked eyes. Binoculars enhance the 3D "ball in shadow" effect.
Important Callouts
KEY TAKEAWAYS
- Not total, but 96% — that tiny bright sliver makes it unique and photogenic
- Peak at 12:12 AM Friday (Boston time) — set an alarm!
- Red "Blood Moon" color is real, safe, and caused by Earth’s atmosphere
- Visible across the Americas — no special equipment required
- Weather is the wildcard — check Thursday PM forecast
- Part of a rare "almost tetrad" + deepest partial in a 500-year cycle
Summary
Thursday night brings a spectacular deep partial lunar eclipse — 96% of the Moon will glow eerie red-copper at 12:12 AM Friday (Boston time). It’s the grand finale of an "almost tetrad" (four eclipses in 18 months) and the deepest partial in a 500-year Saros cycle. Visible across the Americas, no equipment needed — just clear skies and a view to the south. Clouds may interfere in New England, so check the forecast. If you miss it, the next total lunar eclipse in this Saros family arrives in 2044!
FAQ
1. Is it safe to look at a lunar eclipse?
Yes! 100% safe. Unlike solar eclipses, you’re looking at the Moon reflecting sunlight — no brighter than a normal full Moon. Stare away!
2. Why isn’t it a total eclipse if 96% is covered?
"Total" means 100% of the Moon enters Earth’s umbra (dark inner shadow). At 96%, a tiny sliver (~4%) still gets direct sunlight. That sliver stays bright white while the rest turns red — a unique sight!
3. What’s the difference between penumbra and umbra?
- Penumbra = Earth’s fuzzy outer shadow (Sun partly blocked). Subtle dimming, hard to notice.
- Umbra = Earth’s dark inner shadow (Sun completely blocked). Sharp, dark, red shadow — the "real" eclipse.
4. Can I see it from [my city]?
If you’re in North/South America (except Alaska/NW Canada), Western Europe, or Western Africa — YES, at least part of it. Check timeanddate.com/eclipse for your exact local times.
5. When’s the next total lunar eclipse visible from the US?
- March 14, 2025 (total) — but that already happened per this article’s timeline
- Next for US: March 3, 2026 (total) — wait, that’s in the past too per article
- Actually: The article mentions the next total in this Saros series is 2044. For any total lunar eclipse visible from US, check NASA’s eclipse page — they occur roughly every 1-2 years somewhere on Earth.
Happy Moon-watching! Hope the skies stay clear for you!
