Upcoming solar and lunar eclipses, screened by region and linked to NASA predictions

An eclipse can be global news yet invisible from one particular city. This local calendar first filters NASA-sourced events by the broad region containing Groningen. It never treats a regional match as a guarantee: weather, horizon and the exact eclipse path still need checking on the linked NASA map.

Why choose Starry Memory

NASA-linked dates — 6 events in the maintained table match the broad region; every entry keeps its NASA source and UTC time.
GPS · IANA reference — Exact reference: Groningen, 53.2192° N, 6.5667° E, Europe/Amsterdam.
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.

For Groningen, an eclipse date becomes useful only when its source, UTC time and local limitations remain attached. Its verifiable starting point is GeoNames 2755251, 53.2192° N, 6.5667° E, in timezone Europe/Amsterdam.

Eclipse dates connected to the wider Netherlands region

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.

For eclipses, these distances prove no visibility. They only help select the right point before opening the NASA path and checking the local horizon.

The astronomical fingerprint of Groningen

Groningen is represented by 53.2192° N, 6.5667° E, in Groningen, using the IANA zone Europe/Amsterdam. This is a high-latitude viewpoint: the relevant celestial pole stands about 53.2° above its horizon. GeoNames record 2755251 supplies the geographic reference; its population field is 244,807 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.

Twelve monthly light estimates for Groningen

The following pairs are approximate daylight / night duration around the 15th of each month: January: 7 h 49 / 16 h 11; February: 9 h 33 / 14 h 27; March: 11 h 30 / 12 h 30; April: 13 h 43 / 10 h 17; May: 15 h 37 / 8 h 23; June: 16 h 41 / 7 h 19; July: 16 h 14 / 7 h 46; August: 14 h 33 / 9 h 27; September: 12 h 24 / 11 h 36; October: 10 h 16 / 13 h 44; November: 8 h 19 / 15 h 41; December: 7 h 18 / 16 h 42. The longest estimated night in this model is December at 16 h 42; the shortest is June at 7 h 19. “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.

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. The HD file is charged once at €3.99.

Frequently asked questions

Does a regional match mean the eclipse is visible from the city?

No. It is a first filter only. Check the NASA path map and local Moon/Sun altitude for the exact coordinates and time.

Can I replace the centre of Groningen 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 Groningen 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. The HD file is charged once at €3.99.
