Storm level needed
Baie-Comeau sits at 49.22N 68.15W in Quebec, Canada. The IGRF-14 centered dipole puts Baie-Comeau at 58.4 degrees geomagnetic latitude, 9.2 degrees closer to the magnetic pole than its map latitude suggests. Baie-Comeau sits at 58.4 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 Rimouski (90 km), Sept-Îles (168 km), Rivière-du-Loup (186 km). Rimouski sits 0.8 degrees lower on the dipole, Kp 5 against 4 here.
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 Baie-Comeau has some civil darkness; the shortest month sample still has 6.2 hours. Every evening of the year at Baie-Comeau clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Baie-Comeau's longest night of the year, Dec 19, has 14 h 27 min of civil night.
Solar midnight at Baie-Comeau, when the sun is lowest, falls at 23:28 on local clocks on December 15 and 00:33 on June 15. That is 32 min before midnight in December and 33 min after midnight in June, the gap set by daylight saving and the equation of time. So at Baie-Comeau 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 Baie-Comeau with 14.4 hours of civil night and June the lightest at 6.2. Across the year Baie-Comeau gets 3,810 hours of civil night. Astronomical night at Baie-Comeau, the sun 18 degrees or more below the horizon, lasts 11.8 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Baie-Comeau at 66% across the year, from 61% in January to 76% in November. In the months with at least 4 hours of civil night Baie-Comeau averages 67%, against a median of 67% for Glow towns in Canada.
Multiplying civil night by the clear share of the sky gives January the best score, 5.5 hours, ahead of February at 4.8. Baie-Comeau's equinox months score 4.2 in March and 3.8 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 Baie-Comeau, on 24% of days. At Baie-Comeau'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 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 Baie-Comeau have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 6 has the most at 4 h. Tonight Baie-Comeau has 11 h 14 min of civil night, 1 h 46 min of it with the moon down.
