Storm level needed
Rouyn-Noranda sits at 48.24N 79.02W in Quebec, Canada. The IGRF-14 centered dipole puts Rouyn-Noranda at 57.4 degrees geomagnetic latitude, 9.1 degrees closer to the magnetic pole than its map latitude suggests. Rouyn-Noranda sits at 57.4 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 Amos (76 km), Val-d'Or (92 km), Timmins (173 km). Amos sits 0.3 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 Rouyn-Noranda has some civil darkness; the shortest month sample still has 6.4 hours. Every evening of the year at Rouyn-Noranda clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Rouyn-Noranda's longest night of the year, Dec 17, has 14 h 20 min of civil night.
Solar midnight at Rouyn-Noranda, when the sun is lowest, falls at 00:11 on local clocks on December 15 and 01:16 on June 15. That is 11 min after midnight in December and 1 h 16 min after midnight in June, the gap set by daylight saving and the equation of time. So at Rouyn-Noranda 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 Rouyn-Noranda with 14.3 hours of civil night and June the lightest at 6.4. Across the year Rouyn-Noranda gets 3,825 hours of civil night. Astronomical night at Rouyn-Noranda, the sun 18 degrees or more below the horizon, lasts 11.7 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Rouyn-Noranda at 69% across the year, from 63% in March to 82% in November. In the months with at least 4 hours of civil night Rouyn-Noranda averages 69%, against a median of 67% for Glow towns in Canada.
Multiplying civil night by the clear share of the sky gives March the best score, 4.1 hours, ahead of January at 3.9. Rouyn-Noranda's equinox months score 4.1 in March and 3.7 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 5 or more, the level that puts the average oval edge over Rouyn-Noranda, on 10% of days. At Rouyn-Noranda's level the share runs from 5% in December to 14% in September, while storm days with Kp 5 or more made up 10%.

Moon, next 30 nights
Over the 30 nights from Oct 1, the new moon falls on Oct 10 and the full moon on Oct 26, in America/Toronto dates. 15 of the 30 nights at Rouyn-Noranda have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 5 has the most at 4 h. Tonight Rouyn-Noranda has 11 h 14 min of civil night, 1 h 54 min of it with the moon down.
