Quick facts
- Name: Leonid meteor shower
- Peak night: November 17–18, 2025
- Best time to watch: After midnight through dawn
- Radiant: Constellation Leo
- Typical rate at peak: ~10–15 meteors per hour under dark skies
- Parent body: Comet 55P/Tempel‑Tuttle
- Active window: Early November through early December
When and where to watch
The Leonid meteor shower peaks on the night of November 17–18. The best viewing window for most observers is after midnight local time on November 17 into the early morning of November 18, when the constellation Leo climbs higher and the radiant is well positioned. Under dark skies you can expect roughly 10–15 meteors per hour at peak; meteors will appear to radiate from Leo but can show up anywhere in the sky.
What to expect and why the Leonids matter
Leonids are produced when Earth passes through debris left by comet 55P/Tempel‑Tuttle. They enter the atmosphere at very high speed, producing fast, often bright streaks. Most years bring a modest display, but the Leonids are historically notable for short, intense storms when Earth crosses dense filaments of debris—most famously in 1833 and 1966, when observers reported exceptional rates.
History and famous Leonid storms
- 1833: A dramatic storm over North America that helped spark modern meteor science.
- 1866: A major display tied to recent returns of Tempel‑Tuttle.
- 1966: The 20th‑century benchmark Leonid storm with extraordinary rates in parts of the world.
Tempel‑Tuttle’s roughly 33‑year orbital period can deposit denser trails that occasionally produce unusually strong displays.

2025 specifics and visibility
Current predictions place a peak near 18:00 UTC on November 17, 2025; for most viewers the best observing window will be after local midnight into the early dawn of November 18. Expected rates are around 10–15 meteors per hour from a dark site. Check a reliable sky map or planetarium app on the night of the event to confirm when Leo rises for your location and to account for local cloud cover or moonlight.
How to find Leo and where to look
- Find Leo: Look for the bright star Regulus and the Sickle (a backwards question‑mark asterism); Leo rises in the east–southeast after midnight in mid‑November.
- Where to look: Lie back and scan a wide area of sky rather than staring only at the radiant; the east‑southeast to southern sky is often productive after midnight when Leo is higher.
- Comfort: Dress warmly, bring a reclining chair or blanket, and allow 20–30 minutes for your eyes to adapt to the dark.
Tips for photographing the Leonids
- Gear: Sturdy tripod, wide‑angle fast lens (f/2.8 or faster), camera with manual control.
- Settings (starting point): ISO 1600–3200, aperture wide open, exposures 10–30 seconds depending on focal length and sky brightness.
- Technique: Use interval shooting or an intervalometer, aim wide to maximize sky coverage, and include a foreground element for context.
- Expectation: Leonids are fast; capture rates vary, so plan for long sessions and many frames.
Urban viewing tips
- Choose the darkest nearby park or rooftop with the least direct lighting.
- Use a red flashlight to preserve night vision and allow 20–30 minutes for dark adaptation.
- Shield or block direct lights when possible and position yourself to minimize light sources in your field of view.
- Expect reduced visible rates in heavily light‑polluted areas and plan for patience and longer observing windows.
Plan to watch from a dark location, check the weather and a local sky map for Leo’s rise time, and give yourself several hours—Leonids are fast and intermittent, so longer observing increases your chance of seeing bright streaks.
