Quadrantids from Hangzhou in 2026

Worth planning for

Quadrantids: a bright Moon spoils it

Plan for 04:00–06:00 local time: the radiant reaches 57° above the horizon, a 100%-lit Moon sits above the horizon for most of it, and astronomical darkness lasts 10 h 55 min. Under the reference dark sky that rates about 38 meteors an hour — cloud cover is a runtime fact this page cannot know, so treat it as the ceiling, not a promise.

Quadrantids from Hangzhou: the short answer

The Quadrantids reaches maximum at 05:12 local time on 4 January 2026 over Hangzhou, Zhejiang (30.3°N, 120.16°E, 12 m). The radiant culminates 70.7° high at 08:24 and the useful window runs 04:00–06:00, with an ideal-sky ceiling of 37.7 meteors an hour.

That ranks it 3rd of twelve from Hangzhou this year, behind the Geminids (149.9/h) and the Perseids (77.1/h).

The radiant track over this city

Bootes carries the radiant. From Hangzhou it clears the horizon at 23:30 on a bearing of 28° (NNE), reaches 70.7° at 08:24 in the north, and drops back below the horizon at 17:20. Within the observing window it peaks at 56.7°.

When it gets dark here

Sunset over Hangzhou is 17:11, civil twilight ends 17:37, and the sky reaches astronomical darkness — Sun 18° down — at 18:36. It holds until 05:31, with sunrise at 06:56: 10 h 55 min of real darkness inside 13 h 45 min of night.

Local solar midnight, the true middle of the night, falls at 00:03 here rather than at 00:00: Asia/Shanghai runs 1 minute behind mean solar time at 120.16°E. That offset is why the best hour on this page is not the hour you would guess from the clock.

What the Moon does here

Moonlight is the limiting factor on this night from Hangzhou. The Moon is 100% lit and only 0 of 13 sampled hours are moon-free. Moonrise 16:53. Moonset 07:44. At the best hour it stands 31.1° above the horizon, 87° from the radiant, pulling the limiting magnitude down to 5.47.

Why 38 an hour and not 110

Zenithal hourly rate 110, population index 2.1, entry speed 40.4 km/s — fast. Those are stream constants. What changes from city to city is the geometry: at 56.7° of radiant altitude and limiting magnitude 5.47, Hangzhou converts that ZHR into about 37.7 meteors an hour.

Hour by hour the modelled rate runs from 0.0 at 18:00 (radiant -3.6°) to 6.7 at 06:00 (radiant 56.7°), peaking at 37.7. That spread across 13 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Minor planet 2003 EH1 and Comet C/1490 Y1 and is listed as active 28 December to 12 January, so 4 January 2026 is the best night from Hangzhou rather than the only one.

Watching from around Hangzhou

Hangzhou, Zhejiang is the 27th largest of the 300 cities covered here, with a population of 9.24 million at 12 m above sea level. The nearest other cities on the site are Shaoxing (52 km SE), Puyang (97 km SSW), Suzhou (120 km NNE) — close enough that the radiant altitudes barely change, far enough that sunset and moonrise do.

What this page does not know

Light-pollution data for this location is not connected yet. Rates on this page are computed against the reference rural sky the zenithal hourly rate is defined for (naked-eye limiting magnitude 6.5); they are not a claim about how bright the sky is where you are standing. Once the light-pollution layer is connected these figures will be recomputed for the local sky and will generally fall.

Cloud cover is a forecast, not a constant, so it is resolved when you load the tonight card and is deliberately absent from this prerendered page — the hourly table shows "unavailable" rather than assuming clear skies. Meteor outbursts, local terrain and building horizons are not modelled.

A single observer with an unobstructed horizon typically records 30–50% below the ideal-sky figure. Give your eyes twenty minutes to adapt, keep bright screens away, look about halfway up the sky rather than straight at the radiant, and count for a full hour before judging a shower.

"Cloud: n/a" means the forecast is not resolved on this prerendered page, not that the sky is clear.
