Storm level needed
Västra Frölunda sits at 57.65N 11.93E in Västra Götaland, Sweden. The IGRF-14 centered dipole puts Västra Frölunda at 57.3 degrees geomagnetic latitude, 0.3 degrees farther from the magnetic pole than its map latitude suggests. Västra Frölunda sits at 57.3 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 5, and aurora is usually visible on the northern horizon at G1 (Kp 5) or less.
"aurora is commonly visible at high latitudes (northern Michigan and Maine)"
The nearest other Glow towns are Gothenburg (7 km), Kungsbacka (20 km), Lerum (24 km). Gothenburg sits 0.1 degrees higher on the dipole and needs the same Kp.
Approximate: SWPC calls its Kp to latitude rule an average, and a centered dipole can differ by a degree from fuller field models. How the storm level is matched
The year in darkness
Every night of 2026 at Västra Frölunda has some civil darkness; the shortest month sample still has 3.3 hours. Glow's dark season, at least 4 hours of civil night between 18:00 and 06:00, runs from July 11 to May 31 across New Year, 325 days in 2026. Västra Frölunda's longest night of the year, Dec 20, has 15 h 37 min of civil night.
Solar midnight at Västra Frölunda, when the sun is lowest, falls at 00:07 on local clocks on December 15 and 01:13 on June 15. That is 7 min after midnight in December and 1 h 13 min after midnight in June, the gap set by daylight saving and the equation of time. So at Västra Frölunda the darkest hour sits near the middle of SWPC's 10 PM to 2 AM window in winter.

Across the year Västra Frölunda gets 3,607 hours of civil night. Astronomical night at Västra Frölunda, the sun 18 degrees or more below the horizon, lasts 12.3 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Västra Frölunda at 73% across the year, from 63% in June to 86% in January. In the months with at least 4 hours of civil night Västra Frölunda averages 74%, against a median of 75% for Glow towns in Sweden.
Multiplying civil night by the clear share of the sky gives October the best score, 3.2 hours, ahead of September at 3.0. Västra Frölunda's equinox months score 2.8 in March and 3.0 in September, the weeks SWPC links with larger storms.
Kp history
From 1996 to 2025, the GFZ Potsdam record shows a 3-hour Kp of 5 or more, the level that puts the average oval edge over Västra Frölunda, on 10% of days. At Västra Frölunda's level the share runs from 5% in December to 14% in September, while storm days with Kp 5 or more made up 10%.

Questions
- Can you see the northern lights in Västra Frölunda?
- Västra Frölunda sits at 57.3 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 5, and aurora is usually visible on the northern horizon at G1 (Kp 5) or less. Clear, dark sky over Västra Frölunda still decides it.
- When is it dark enough in Västra Frölunda?
- Every night at Västra Frölunda has civil darkness. Tonight has 11 h 12 min, and December 15 has 15.6 hours.
- What is the best month for aurora in Västra Frölunda?
- October, by civil night at Västra Frölunda times the clear share of the sky from NASA POWER's 2001 to 2020 average.
- How cloudy is Västra Frölunda in the dark months?
- About 74% mean cloud amount over Västra Frölunda in the months with at least 4 hours of civil night, from NASA POWER's 2001 to 2020 all-hours climatology.
- How often is activity high enough for Västra Frölunda?
- A 3-hour Kp of 5 or more, the level that puts the average oval edge overhead, occurred on 10% of days from 1996 to 2025 in the GFZ Potsdam record.
- Why does this page point to Gothenburg?
- Västra Frölunda sits within 15 km of Gothenburg with the same rounded dipole latitude, Kp and dark season, so Glow treats Gothenburg as the main page for both.
