Storm level needed
Valley East sits at 46.65N 81.00W in Ontario, Canada. The IGRF-14 centered dipole puts Valley East at 55.7 degrees geomagnetic latitude, 9.1 degrees closer to the magnetic pole than its map latitude suggests. Valley East sits at 55.7 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 Greater Sudbury (17 km), North Bay (123 km), Timmins (204 km). Greater Sudbury sits 0.2 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 Valley East has some civil darkness; the shortest month sample still has 6.7 hours. Every evening of the year at Valley East clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Valley East's longest night of the year, Dec 16, has 14 h 10 min of civil night.
Solar midnight at Valley East, when the sun is lowest, falls at 00:19 on local clocks on December 15 and 01:24 on June 15. That is 19 min after midnight in December and 1 h 24 min after midnight in June, the gap set by daylight saving and the equation of time. So at Valley East the darkest hour sits near the middle of SWPC's 10 PM to 2 AM window in winter.

Astronomical night at Valley East, 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 Valley East at 65% across the year, from 54% in July to 77% in November. In the months with at least 4 hours of civil night Valley East averages 65%, 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, 4.4 hours, ahead of September at 4.4. Valley East's equinox months score 4.4 in March and 4.4 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 Valley East, on 3% of days. At Valley East's level the share runs from 1% in December to 5% in October, while storm days with Kp 5 or more made up 10%.
