The exact sky of a meaningful Dallas moment, calculated before you buy

A place is not a decorative caption on a star map. For a memory in Dallas, the selected coordinates, local time and timezone determine the celestial orientation. This guide starts with a free, location-aware sky and phone gyroscope; the watermark-free HD poster is an optional keepsake after you have checked the result.

Why choose Starry Memory

  • A place-driven gift — Dallas starts at 32.7831° N, 96.8067° W; choosing a venue or address replaces that centre point before the poster is calculated.
  • GPS · IANA reference — Exact reference: Texas, 32.7831° N, 96.8067° W, America/Chicago.
  • Free tool — The city-specific tool works free in the browser and does not create an order.
  • Transparent limits — Weather, light pollution and local obstructions are stated as limits instead of being hidden.

In Dallas, the keepsake begins with a real point on Earth before it becomes an image of the sky. Its verifiable starting point is GeoNames 4684888, 32.7831° N, 96.8067° W, in timezone America/Chicago.

The astronomical fingerprint of Dallas

Dallas is represented by 32.7831° N, 96.8067° W, in Texas, using the IANA zone America/Chicago. This is a mid-latitude viewpoint: the relevant celestial pole stands about 32.8° above its horizon. GeoNames record 4684888 supplies the geographic reference; its population field is 1,326,087 and is used for catalogue selection, not presented as a live census. The source elevation is 128 metres; terrain can hide a low object even when the geometric calculation says it rises. The following pairs are approximate daylight / night duration around the 15th of each month: January: 10 h 04 / 13 h 56; February: 10 h 50 / 13 h 10; March: 11 h 46 / 12 h 14; April: 12 h 49 / 11 h 11; May: 13 h 41 / 10 h 19; June: 14 h 09 / 9 h 51; July: 13 h 58 / 10 h 02; August: 13 h 13 / 10 h 47; September: 12 h 11 / 11 h 49; October: 11 h 10 / 12 h 50; November: 10 h 17 / 13 h 43; December: 9 h 51 / 14 h 09. The longest estimated night in this model is December at 14 h 09; the shortest is June at 9 h 51. “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.

For a gift, the comparison explains why the confirmed place matters: a Dallas memory should not silently become its neighbour even when both share a timezone.

Latitude-screened constellations for Dallas

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: 62.8°, all year *; Draco: 57.8°, all year *; Cepheus: 52.8°, all year *; Ursa Minor: 45.8°, all year *; Boötes: 87.2°, spring; Lyra: 86.8°, summer; Andromeda: 84.8°, autumn; Cygnus: 82.8°, summer; Auriga: 80.8°, winter; Gemini: 79.2°, winter; Perseus: 77.8°, winter; Taurus: 75.2°, winter; Leo: 72.2°, spring; Ursa Major: 66.8°, 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.

Eclipse dates connected to the wider United States region

20 February 2027: Penumbral lunar eclipse, 23:14 UTC; 17 August 2027: Penumbral lunar eclipse, 07:14 UTC; 12 January 2028: Partial lunar eclipse, 04:14 UTC; 26 January 2028: Annular solar eclipse, 15:08 UTC; 14 January 2029: Partial solar eclipse, 17:13 UTC; 12 June 2029: Partial solar eclipse, 04:06 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.

What the calculation does — and does not claim

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.

Free gyroscope first, optional poster second

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 US dollars (USD).

Frequently asked questions

What makes a Dallas star map personal?

The confirmed date, local time and coordinates determine the map. The city shortcut is 32.7831° N, 96.8067° W, but an exact selected venue can replace it.

Can I replace the centre of Dallas with an exact address?

Yes. Choose the intended autocomplete suggestion; its coordinates replace the city shortcut. Unselected free text is never silently sent to a default city.

Is the Dallas tool free?

Yes. The local calculation, tables and gyroscope exploration can be used without payment. Only the unlocked HD poster is paid.

Does this guarantee clear-sky visibility?

No. The calculations describe geometry. Cloud, terrain, buildings and light pollution can change what a person sees from the ground.

Do I have to buy a poster?

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 US dollars (USD).
