A free local guide to the Moon, planets and constellations visible tonight
The night sky changes with both time and place. This page calculates tonight above Västerås from its coordinates and local timezone, then lets you refine the location. The live tool identifies the Moon, bright planets and recognisable constellations around 22:00 local time without requiring a purchase.
Tonight in Västerås is neither yesterday's sky nor another latitude's view: the calculation restarts from local place and time. Its verifiable starting point is GeoNames 2664454, 59.6162° N, 16.5528° E, in timezone Europe/Stockholm.
Västerås is represented by 59.6162° N, 16.5528° E, in Västmanland, using the IANA zone Europe/Stockholm. This is a high-latitude viewpoint: the relevant celestial pole stands about 59.6° above its horizon. GeoNames record 2664454 supplies the geographic reference; its population field is 127,799 and is used for catalogue selection, not presented as a live census. No source elevation is used, so a flat horizon remains the transparent default. Each entry below gives an approximate maximum altitude at meridian transit and a practical season; an asterisk means circumpolar in this simplified centroid model: Cassiopeia: 89.6°, all year *; Ursa Major: 86.4°, all year *; Draco: 84.6°, all year *; Cepheus: 79.6°, all year *; Perseus: 75.4°, all year *; Ursa Minor: 72.6°, all year *; Auriga: 72.4°, all year *; Cygnus: 70.4°, all year *; Andromeda: 68.4°, all year *; Lyra: 66.4°, all year *; Boötes: 60.4°, spring; Gemini: 52.4°, winter; Taurus: 48.4°, winter; Leo: 45.4°, spring. This is a planning guide, not a promise that every star will be visible from a bright street. Date, hour, local obstructions and light pollution still matter. The live sky tool performs the date-specific projection that a static latitude table cannot.

Together these values form the local evidence record for the “tonight” page; they change with place and remain separate from real weather.

Monthly night comparison with the nearest catalogue reference — January: Västerås 17 h 32 / Uppsala 17 h 37 / Δ -0.07 h · February: Västerås 15 h 10 / Uppsala 15 h 12 / Δ -0.03 h · March: Västerås 12 h 38 / Uppsala 12 h 39 / Δ -0.01 h · April: Västerås 9 h 49 / Uppsala 9 h 47 / Δ +0.02 h · May: Västerås 7 h 16 / Uppsala 7 h 13 / Δ +0.05 h · June: Västerås 5 h 42 / Uppsala 5 h 37 / Δ +0.09 h · July: Västerås 6 h 22 / Uppsala 6 h 18 / Δ +0.07 h · August: Västerås 8 h 42 / Uppsala 8 h 40 / Δ +0.03 h · September: Västerås 11 h 30 / Uppsala 11 h 29 / Δ +0.01 h · October: Västerås 14 h 14 / Uppsala 14 h 16 / Δ -0.03 h · November: Västerås 16 h 50 / Uppsala 16 h 53 / Δ -0.05 h · December: Västerås 18 h 19 / Uppsala 18 h 23 / Δ -0.08 h. For tonight's sky, longitude changes local rotation while latitude changes altitude; the tool therefore starts from Västerås and then accepts a more exact address.
The following pairs are approximate daylight / night duration around the 15th of each month: January: 6 h 28 / 17 h 32; February: 8 h 50 / 15 h 10; March: 11 h 22 / 12 h 38; April: 14 h 11 / 9 h 49; May: 16 h 44 / 7 h 16; June: 18 h 18 / 5 h 42; July: 17 h 38 / 6 h 22; August: 15 h 18 / 8 h 42; September: 12 h 30 / 11 h 30; October: 9 h 46 / 14 h 14; November: 7 h 10 / 16 h 50; December: 5 h 41 / 18 h 19. The longest estimated night in this model is December at 18 h 19; the shortest is June at 5 h 42. “Night” here is the complement of daylight on a flat horizon. Civil, nautical and astronomical twilight are not interchangeable, and weather is not predicted by this table.
20 February 2027: Penumbral lunar eclipse, 23:14 UTC; 2 August 2027: Total solar eclipse, 10:07 UTC; 12 January 2028: Partial lunar eclipse, 04:14 UTC; 26 January 2028: Annular solar eclipse, 15:08 UTC; 6 July 2028: Partial lunar eclipse, 18:20 UTC; 31 December 2028: Total lunar eclipse, 16:53 UTC. This is deliberately a regional shortlist. Solar-eclipse paths are narrow, lunar eclipses require the Moon to be above the local horizon, and both can be lost to cloud. Open the NASA source attached to each event before planning travel or observation; never look at the Sun without certified eclipse viewers.
Coordinates, date and local time feed the same astronomical workflow used by the poster. The HYG catalogue provides star entries, while Astronomy Engine calculates moving bodies. The page does not claim that city-centre coordinates equal a hospital, venue or home: selecting an autocomplete suggestion replaces the shortcut with that location. It also separates astronomical geometry from weather and light pollution, so a correct map never becomes a claim that the ground-level sky was cloudless.
On a compatible phone, the gyroscope turns the calculated sky into a movable window: tilt and rotate to explore, with star names shown beside key points. That experience is free. If a date deserves a keepsake, the same place can continue into the editor. The protected preview remains watermarked before payment; the €3.99 purchase unlocks the 4960 × 7016 px, 300 DPI file. Physical formats appear only when availability, delivery supplement and timing can be checked for the destination. Checkout is in euros; the card issuer shows the current conversion to Swedish kronor (SEK).
The current summary targets about 22:00 local time in Europe/Stockholm. Recalculate after changing place; planetary altitude and constellation visibility move through the night.
Yes. Choose the intended autocomplete suggestion; its coordinates replace the city shortcut. Unselected free text is never silently sent to a default city.
Yes. The local calculation, tables and gyroscope exploration can be used without payment. Only the unlocked HD poster is paid.
No. The calculations describe geometry. Cloud, terrain, buildings and light pollution can change what a person sees from the ground.
No. The tool stands on its own. If wanted, the watermark-free 4960 × 7016 px, 300 DPI file costs €3.99. Checkout is in euros; the card issuer shows the current conversion to Swedish kronor (SEK).
