Quadrantids from Harbin in 2026

Quadrantids from Harbin: the short answer

The Quadrantids reaches maximum at 05:12 local time on 4 January 2026 over Harbin, Heilongjiang (45.8°N, 126.65°E, 140 m). The radiant culminates 86.1° high at 07:58 and the useful window runs 04:00–06:00, with an ideal-sky ceiling of 46.8 meteors an hour.

That ranks it 3rd of twelve from Harbin this year, behind the Geminids (145.4/h) and the Perseids (84.5/h).

The radiant track over this city

The radiant is circumpolar from 45.8°N: it never sets. Over the night it swings between its low point and 86.1° at 07:58, bearing N (360°) at culmination. It sits inside Bootes, and because it is above the horizon for every dark hour, what limits you here is darkness and moonlight, not geometry.

When it gets dark here

Sunset over Harbin is 16:01, civil twilight ends 16:35, and the sky reaches astronomical darkness — Sun 18° down — at 17:49. It holds until 05:26, with sunrise at 07:14: 11 h 38 min of real darkness inside 15 h 13 min of night.

Local solar midnight, the true middle of the night, falls at 23:37 here rather than at 00:00: Asia/Shanghai runs 27 minutes behind mean solar time at 126.65°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 Harbin. The Moon is 100% lit and only 0 of 14 sampled hours are moon-free. Moonrise 15:26. Moonset 08:11. At the best hour it stands 28.8° above the horizon, 87° from the radiant, pulling the limiting magnitude down to 5.54.

Why 47 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 69.8° of radiant altitude and limiting magnitude 5.54, Harbin converts that ZHR into about 46.8 meteors an hour.

Hour by hour the modelled rate runs from 0.9 at 17:00 (radiant 13.2°) to 8.6 at 06:00 (radiant 69.8°), peaking at 46.8. That spread across 14 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 Harbin rather than the only one.

Watching from around Harbin

Harbin, Heilongjiang is the 54th largest of the 300 cities covered here, with a population of 5.24 million at 140 m above sea level. The nearest other cities on the site are Daqing (157 km NW), Jilin (212 km S), Changchun (233 km SSW) — 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.
