eta-Aquariids from Dalian in 2026

Worth planning for

eta-Aquariids: a bright Moon spoils it

Plan for 03:00–04:00 local time: the radiant reaches 28° above the horizon, a 79%-lit Moon sits above the horizon for most of it, and astronomical darkness lasts 6 h 32 min. Under the reference dark sky that rates about 9 meteors an hour — cloud cover is a runtime fact this page cannot know, so treat it as the ceiling, not a promise.

eta-Aquariids from Dalian: the short answer

Dalian, Liaoning is at 38.9°N and 33 m, which puts the eta-Aquariids radiant 51.0° up at culmination (07:32 local time) on the night of maximum, 6 May 2026. Peak activity is 17:01, the reference-sky rate tops out at 8.6 an hour, and 03:00–04:00 is the stretch to be outside.

That ranks it 7th of twelve from Dalian this year, behind the Geminids (149.0/h) and the Perseids (84.9/h).

The radiant track over this city

At 38.9°N a declination-−0.5° radiant traces an arc from 01:32 to 13:31, topping out at 51.0° at 07:32 bearing 180°. Inside the dark window it only manages 27.8°, and that lower figure is the one the rates are built from. The radiant currently lies in Aquarius.

When it gets dark here

Sunset over Dalian is 18:50, civil twilight ends 19:19, and the sky reaches astronomical darkness — Sun 18° down — at 20:34. It holds until 03:05, with sunrise at 04:49: 6 h 32 min of real darkness inside 9 h 59 min of night.

Local solar midnight, the true middle of the night, falls at 23:49 here rather than at 00:00: Asia/Shanghai runs 6 minutes behind mean solar time at 121.60°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 Dalian. The Moon is 79% lit and only 4 of 9 sampled hours are moon-free. Moonrise 23:19. Moonset 08:23. At the best hour it stands 22.3° above the horizon, 60° from the radiant, pulling the limiting magnitude down to 5.91.

Why 9 an hour and not 50

Zenithal hourly rate 50, population index 2.4, entry speed 66.3 km/s — very fast. Those are stream constants. What changes from city to city is the geometry: at 27.8° of radiant altitude and limiting magnitude 5.91, Dalian converts that ZHR into about 8.6 meteors an hour.

Hour by hour the modelled rate runs from 0.0 at 20:00 (radiant -50.9°) to 0.3 at 04:00 (radiant 27.8°), peaking at 8.6. That spread across 9 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Comet 1P/Halley and is listed as active 19 April to 27 May, so 6 May 2026 is the best night from Dalian rather than the only one.

Watching from around Dalian

Dalian, Liaoning is the 57th largest of the 300 cities covered here, with a population of 4.91 million at 33 m above sea level. The nearest other cities on the site are Yantai (160 km S), Anshan (273 km NNE), Tangshan (305 km WNW) — 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.
