Storm level needed
Kumla sits at 59.13N 15.14E in Örebro, Sweden. The IGRF-14 centered dipole puts Kumla at 58.2 degrees geomagnetic latitude, 0.9 degrees farther from the magnetic pole than its map latitude suggests. Kumla sits at 58.2 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 Örebro (17 km), Karlskoga (42 km), Kristinehamn (62 km). Örebro 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 Kumla has some civil darkness; the shortest month sample still has 2.1 hours. Glow's dark season, at least 4 hours of civil night between 18:00 and 06:00, runs from July 20 to May 22 across New Year, 307 days in 2026. Kumla's longest night of the year, Dec 20, has 15 h 53 min of civil night.
Solar midnight at Kumla, when the sun is lowest, falls at 23:55 on local clocks on December 15 and 01:00 on June 15. That is 5 min before midnight in December and 1 h after midnight in June, the gap set by daylight saving and the equation of time. So at Kumla 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 Kumla with 15.8 hours of civil night and June the lightest at 2.1. Across the year Kumla gets 3,538 hours of civil night. Astronomical night at Kumla, the sun 18 degrees or more below the horizon, lasts 12.4 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Kumla at 74% across the year, from 69% in April to 82% in January. In the months with at least 4 hours of civil night Kumla averages 75%, 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, 3.1 hours, ahead of November at 3.1. Kumla's equinox months score 2.8 in March and 2.7 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 Kumla, on 24% of days. At Kumla'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/Stockholm dates. 15 of the 30 nights at Kumla have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 6 has the most at 4 h. Tonight Kumla has 11 h 10 min of civil night, 54 min of it with the moon down.
