Storm level needed
Miramichi sits at 47.03N 65.50W in New Brunswick, Canada. The IGRF-14 centered dipole puts Miramichi at 56.1 degrees geomagnetic latitude, 9.1 degrees closer to the magnetic pole than its map latitude suggests. Miramichi sits at 56.1 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 Lutes Mountain (108 km), Moncton (117 km), Fredericton (150 km). Lutes Mountain sits 0.9 degrees lower on the dipole, Kp 6 against 5 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 Miramichi has some civil darkness; the shortest month sample still has 6.7 hours. Every evening of the year at Miramichi clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Miramichi's longest night of the year, Dec 19, has 14 h 13 min of civil night.
Solar midnight at Miramichi, when the sun is lowest, falls at 00:17 on local clocks on December 15 and 01:22 on June 15. That is 17 min after midnight in December and 1 h 22 min after midnight in June, the gap set by daylight saving and the equation of time. So at Miramichi 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 Miramichi with 14.2 hours of civil night and June the lightest at 6.7. Across the year Miramichi gets 3,842 hours of civil night. Astronomical night at Miramichi, 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 Miramichi at 66% across the year, from 54% in September to 74% in November. In the months with at least 4 hours of civil night Miramichi averages 66%, against a median of 67% for Glow towns in Canada.
Multiplying civil night by the clear share of the sky gives September the best score, 4.7 hours, ahead of October at 4.3. Miramichi's equinox months score 3.6 in March and 4.7 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 Miramichi, on 10% of days. At Miramichi'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/Moncton dates. 15 of the 30 nights at Miramichi have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 5 has the most at 4 h. Tonight Miramichi has 11 h 14 min of civil night, 1 h 59 min of it with the moon down.
