Orionids 2026: A Viewing Guide to Halley's Comet Debris
When to watch, how moonlight affects the view, and why these meteors are a connection to Halley's Comet.
OCTOBER 9, 2026
Mark the night of October 21–22
NASA and the American Meteor Society list October 21–22 as the 2026 peak night. Watch after midnight and before dawn on October 22, and consider nearby mornings too. A shower's maximum is a window, rather than a guaranteed appointment at 3 a.m.
The waxing gibbous Moon will wash out faint meteors while it is above the horizon. Check local moonset and weather before choosing your viewing time. A darker interval before dawn may offer a better view.
How to watch
- Choose a safe, accessible location away from bright lights, with a broad view of the sky.
- Bring a reclining chair and warm clothing. Give your eyes about 30 minutes to adapt.
- Use your unaided eyes; watch a wide sky area rather than staring at Orion.
- Allow plenty of time. Dark-sky rates of around 10–20 meteors per hour are an ideal-condition guide, not a promise for your location.
What creates the streaks?
Earth crosses debris shed by comet 1P/Halley. Particles enter the atmosphere at about 66 kilometres per second, producing brief luminous streaks and sometimes lingering trails. They appear to radiate from near Orion, but the constellation is a direction marker, not their physical source.
A simple observing experiment
Record the date, location, cloud cover, moonlight and time spent watching. Count meteors in equal time blocks. Compare observations with a friend at another location: how much of the difference might reflect the sky conditions rather than the shower itself?
