Sky guide, 69.6°N
The night sky over Tromsø
What changes through the year in the sky above Tromsø: how dark it gets, which constellations you can and cannot see, and what the eclipses and meteor showers of 2026 and 2027 look like from here.
Sunrise, sunset and darkness through 2026
Tromsø is at 69.6°N. The table gives sunrise, sunset and day length on the 15th of each month in local time (Europe/Oslo), and the hours of full astronomical darkness, when the Sun is more than 18 degrees below the horizon and the faintest stars and the Milky Way show. The longest dark nights are around December, with about 13 h 30 min of darkness. The Sun stays above the horizon all day from 18 May to 25 July. The Sun does not rise from 1 January to 14 January and 28 November to 31 December.

Constellations and your latitude
How much of the sky you can see depends on latitude. From Tromsø, in the northern hemisphere, 17 constellations never set: Andromeda, Auriga, Camelopardalis, Canes Venatici, Cassiopeia, Cepheus, Corona Borealis, Cygnus, Draco, Lacerta, Leo Minor, Lynx, Lyra, Perseus, Triangulum, Ursa Major and Ursa Minor. 34 never rise above the horizon: Antlia, Apus, Ara, Caelum, Carina, Centaurus, Chamaeleon, Circinus, Columba, Corona Australis, Crux, Dorado, Fornax, Grus, Horologium, Hydrus, Indus, Lupus, Mensa, Microscopium, Musca, Norma, Octans, Pavo, Phoenix, Pictor, Piscis Austrinus, Reticulum, Sculptor, Telescopium, Triangulum Australe, Tucana, Vela and Volans. 16 more only partly clear it: Aquarius, Canis Major, Capricornus, Cetus, Corvus, Crater, Eridanus, Hydra, Lepus, Libra, Ophiuchus, Puppis, Pyxis, Sagittarius, Scorpius and Virgo. These come from the IAU's constellation boundaries and are geometric, so they ignore haze, hills and buildings near the horizon.
Eclipses from Tromsø, 2026 and 2027
| Date | Eclipse | From Tromsø |
|---|---|---|
| 17 Feb 2026 | Annular solar eclipse | Not visible from here |
| 3 Mar 2026 | Total lunar eclipse | Not visible from here |
| 12 Aug 2026 | Total solar eclipse | Visible from here: 83% of the Sun is covered at the peak, with the Sun 10° up. The greatest eclipse is near 65°N, 25°W. Never look at the Sun without proper eclipse glasses. |

| 6 Feb 2027 | Annular solar eclipse | Not visible from here |
| 21 Feb 2027 | Penumbral lunar eclipse | A penumbral eclipse is a faint shading that is hard to see by eye. From here the Moon is 29° up at the peak. |
| 18 Jul 2027 | Penumbral lunar eclipse | Not visible from here |
| 2 Aug 2027 | Total solar eclipse | Not visible from here |
| 17 Aug 2027 | Penumbral lunar eclipse | Not visible from here |
Meteor showers: how high the radiant gets
The radiant is the point a meteor shower seems to stream from; the higher it climbs, the better the shower works. This is the highest each radiant gets from Tromsø. See the meteor shower table for peak dates and the Moon.
| Shower | Highest radiant | Peak | ZHR |
|---|---|---|---|
| Perseids | 78° | 13 Aug | 110 |
| Draconids | 76° | 9 Oct | 5 |
| Quadrantids | 69° | 4 Jan | 80 |
| Lyrids | 54° | 23 Apr | 18 |
| Geminids | 53° | 14 Dec | 150 |
| Leonids | 42° | 18 Nov | 15 |
| Orionids | 36° | 22 Oct | 20 |
| Southern Taurids | 35° | 6 Nov | 7 |
| Eta Aquariids | 19° | 6 May | 50 |
| Southern Delta Aquariids | 4° | 31 Jul | 25 |
How this was worked out
Sun and darkness times come from the astronomy-engine library. The sunrise and sunset times on both 2026 solstices at this and five other places were compared with the US Naval Observatory's tables (20 times) and the largest difference was 30 seconds. The other mid-month figures use the same calculation but were not compared one by one. Constellation visibility comes from the IAU boundaries.
