Storm level needed
Charlottetown sits at 46.23N 63.13W in Prince Edward Island, Canada. The IGRF-14 centered dipole puts Charlottetown at 55.3 degrees geomagnetic latitude, 9.1 degrees closer to the magnetic pole than its map latitude suggests. Charlottetown sits at 55.3 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 6, 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 Moncton (130 km), Lutes Mountain (138 km), Lower Sackville (168 km). Moncton sits 0.1 degrees lower 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 Charlottetown has some civil darkness; the shortest month sample still has 6.8 hours. Every evening of the year at Charlottetown clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Charlottetown's longest night of the year, Dec 18, has 14 h 8 min of civil night.
Solar midnight at Charlottetown, when the sun is lowest, falls at 00:08 on local clocks on December 15 and 01:13 on June 15. That is 8 min after midnight in December and 1 h 13 min after midnight in June, the gap set by daylight saving and the equation of time. So at Charlottetown the darkest hour sits near the middle of SWPC's 10 PM to 2 AM window in winter.

Across the year Charlottetown gets 3,852 hours of civil night. Astronomical night at Charlottetown, the sun 18 degrees or more below the horizon, lasts 11.6 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Charlottetown at 74% across the year, from 61% in September to 88% in December. In the months with at least 4 hours of civil night Charlottetown averages 74%, 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, 4.1 hours, ahead of August at 3.3. Charlottetown's equinox months score 2.6 in March and 4.1 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 6 or more, the level that puts the average oval edge over Charlottetown, on 3% of days. At Charlottetown's level the share runs from 1% in December to 5% in October, while storm days with Kp 5 or more made up 10%.
