Storm level needed
Nokia sits at 61.47N 23.50E in Pirkanmaa, Finland. The IGRF-14 centered dipole puts Nokia at 59.2 degrees geomagnetic latitude, 2.3 degrees farther from the magnetic pole than its map latitude suggests. Nokia sits at 59.2 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 4, 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 Ylöjärvi (11 km), Tampere (16 km), Lempäälä (21 km). Ylöjärvi 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
From June 1 to July 10 the sun never reaches -6 degrees, so 40 nights in 2026 have no civil darkness at all. SWPC puts it plainly: "It must also be dark so during the summer months at auroral latitudes, the midnight sun prevents auroral observations." Glow's dark season, at least 4 hours of civil night between 18:00 and 06:00, runs from July 30 to May 12 across New Year, 287 days in 2026. Nokia's longest night of the year, Dec 20, has 16 h 22 min of civil night.
Solar midnight at Nokia, when the sun is lowest, falls at 00:21 on local clocks on December 15 and 01:26 on June 15. That is 21 min after midnight in December and 1 h 26 min after midnight in June, the gap set by daylight saving and the equation of time. So at Nokia the darkest hour sits near the middle of SWPC's 10 PM to 2 AM window in winter.

By the 15th-of-the-month sample, December is the darkest month at Nokia with 16.3 hours of civil night and June the lightest at 0.0. Across the year Nokia gets 3,372 hours of civil night. Astronomical night at Nokia, the sun 18 degrees or more below the horizon, lasts 12.5 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Nokia at 73% across the year, from 63% in May to 87% in November. In the months with at least 4 hours of civil night Nokia averages 76%, against a median of 76% for Glow towns in Finland.
Multiplying civil night by the clear share of the sky gives March the best score, 3.3 hours, ahead of September at 2.9. Nokia's equinox months score 3.3 in March and 2.9 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 4 or more, the level that puts the average oval edge over Nokia, on 24% of days. At Nokia's level the share runs from 19% in December to 31% in September, while storm days with Kp 5 or more made up 10%.

Moon, next 30 nights
Over the 30 nights from Oct 2, the new moon falls on Oct 10 and the full moon on Oct 26, in Europe/Helsinki dates. 15 of the 30 nights at Nokia have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 6 has the most at 4 h. Tonight Nokia has 11 h 8 min of civil night, 0 min of it with the moon down.

Each cell is the night that starts on that date. Hours are civil-dark time with the moon below the horizon; the green rule scales with them. Green outline: new moon. Bone outline: full moon.
