Southern delta-Aquariids from Karachi in 2026

Southern delta-Aquariids from Karachi: the short answer

Marginal from Karachi, Sindh. Maximum 18:23 on 31 July 2026; the radiant reaches 49.2° at 02:40 and the ideal-sky rate tops out at 3.4 an hour with the Moon 95% lit.

That ranks it 11th of twelve from Karachi this year, behind the Geminids (148.1/h) and the Perseids (75.2/h).

The radiant track over this city

Aquarius carries the radiant. From Karachi it clears the horizon at 21:10 on a bearing of 108° (ESE), reaches 49.2° at 02:40 in the south, and drops back below the horizon at 08:09. Within the observing window it peaks at 48.9°.

When it gets dark here

Karachi loses the Sun at 19:17 and gets it back at 05:59. True astronomical darkness — the only part that counts for faint meteors — runs 20:41 to 04:35, 7 h 55 min out of 10 h 42 min of night.

Local solar midnight, the true middle of the night, falls at 00:38 here rather than at 00:00: Asia/Karachi runs 32 minutes ahead of mean solar time at 67.01°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 Karachi. The Moon is 95% lit and only 1 of 10 sampled hours are moon-free. Moonrise 20:30. Moonset 08:14. At the best hour it stands 48.1° above the horizon, 8° from the radiant, pulling the limiting magnitude down to 5.09.

Why 3 an hour and not 25

Converting ZHR 25 into something useful for Karachi means multiplying by sin(48.9°) and dividing by 3.2 raised to (6.5 − 5.09). That lands at 3.4 meteors an hour, from fast 40.6 km/s entries.

Hour by hour the modelled rate runs from 0.0 at 20:00 (radiant -15.6°) to 0.3 at 05:00 (radiant 36.9°), 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 Karachi rather than the only one.

Watching from around Karachi

Karachi, Sindh is the 14th largest of the 300 cities covered here, with a population of 11.62 million at 8 m above sea level. The nearest other cities on the site are Hyderabad (150 km ENE), Quetta (592 km N), Ahmedabad (602 km ESE) — 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.
