Southern delta-Aquariids from Kano in 2026

Southern delta-Aquariids from Kano: the short answer

The Southern delta-Aquariids peaks at 14:23 local time on 31 July 2026 over Kano. Culmination is 02:33 at 62.1° — 88% of the rate a zenith radiant would give — so the ceiling here is 3.4 an hour, not worth the sleep.

That ranks it 10th of twelve from Kano this year, behind the Geminids (139.8/h) and the Perseids (66.9/h).

The radiant track over this city

At 12.0°N a declination-−16.1° radiant traces an arc from 20:48 to 08:19, topping out at 62.1° at 02:33 bearing 180°. Inside the dark window it only manages 61.4°, and that lower figure is the one the rates are built from. The radiant currently lies in Aquarius.

When it gets dark here

The dark hours here run 20:07 to 04:57 — 8 h 51 min of astronomical night, bracketed by sunset at 18:51 and sunrise at 06:13. Civil twilight ends at 19:14; anything earlier than that is wasted effort.

Local solar midnight, the true middle of the night, falls at 00:32 here rather than at 00:00: Africa/Lagos runs 26 minutes ahead of mean solar time at 8.52°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 Kano. The Moon is 95% lit and only 1 of 10 sampled hours are moon-free. Moonrise 20:19. Moonset 08:24. At the best hour it stands 36.4° above the horizon, 8° from the radiant, pulling the limiting magnitude down to 5.37.

Why 3 an hour and not 25

The published ZHR of 25 assumes the radiant overhead and a sky at limiting magnitude 6.5. Here the radiant reaches 61.4° inside the dark window and the limiting magnitude at the best hour is 5.37, which with r = 3.2 gives 3.4 an hour. Entry speed is 40.6 km/s.

Hour by hour the modelled rate runs from 0.0 at 20:00 (radiant -11.3°) to 2.8 at 05:00 (radiant 44.4°), peaking at 3.4. That spread across 10 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Comet 96P/Machholz and is listed as active 12 July to 23 August, so 31 July 2026 is the best night from Kano rather than the only one.

Watching from around Kano

Kano is the 58th largest of the 300 cities covered here, with a population of 4.91 million at 484 m above sea level. The nearest other cities on the site are Kaduna (202 km SW), Abuja (346 km SSW), Onitsha (678 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.
