Orionids from Bengaluru in 2026

Orionids from Bengaluru: the short answer

The Orionids peaks at 23:53 local time on 21 October 2026 over Bengaluru, Karnataka. Culmination is 04:40 at 87.3° — 100% of the rate a zenith radiant would give — so the ceiling here is 3.1 an hour, not worth the sleep.

That ranks it 5th of twelve from Bengaluru this year, behind the Geminids (20.9/h) and the Perseids (13.0/h).

The radiant track over this city

At 13.0°N a declination-+15.7° radiant traces an arc from 22:26 to 10:55, topping out at 87.3° at 04:40 bearing 360°. Inside the dark window it only manages 84.6°, and that lower figure is the one the rates are built from. The radiant currently lies in Orion.

When it gets dark here

The dark hours here run 19:08 to 04:59 — 9 h 51 min of astronomical night, bracketed by sunset at 17:57 and sunrise at 06:11. Civil twilight ends at 18:19; anything earlier than that is wasted effort.

Local solar midnight, the true middle of the night, falls at 00:04 here rather than at 00:00: Asia/Kolkata runs 20 minutes ahead of mean solar time at 77.59°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 Bengaluru. The Moon is 79% lit and only 3 of 11 sampled hours are moon-free. Moonrise 14:33. Moonset 02:33. At the best hour it stands 20.9° below the horizon, pulling the limiting magnitude down to 4.50.

Why 3 an hour and not 20

The published ZHR of 20 assumes the radiant overhead and a sky at limiting magnitude 6.5. Here the radiant reaches 84.6° inside the dark window and the limiting magnitude at the best hour is 4.50, which with r = 2.5 gives 3.1 an hour. Entry speed is 66.1 km/s.

Hour by hour the modelled rate runs from 0.0 at 19:00 (radiant -45.3°) to 3.1 at 05:00 (radiant 84.6°), peaking at 3.1. That spread across 11 hours is why a "what time" answer beats a "how many" answer.

The stream comes from Comet 1P/Halley and is listed as active 2 October to 7 November, so 21 October 2026 is the best night from Bengaluru rather than the only one.

Watching from around Bengaluru

Bengaluru, Karnataka is the 31st largest of the 300 cities covered here, with a population of 8.50 million at 920 m above sea level. The nearest other cities on the site are Kallakurichi (202 km SE), Coimbatore (229 km SSW), Chennai (291 km E) — close enough that the radiant altitudes barely change, far enough that sunset and moonrise do.

What this page does not know

Rates on this page are computed against this city's own measured sky brightness, derived from satellite night-lights data. That is a calculated brightness for the point directly overhead, not a survey of your street: a park on the edge of town and a lit car park in the centre share the same figure here and will not look the same. It is also zenith-only, while the Bortle scale describes the whole sky from horizon to horizon.

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.
