Storm level needed
Sosnovyy Bor sits at 59.90N 29.09E in Leningradskaya Oblast', Russia. The IGRF-14 centered dipole puts Sosnovyy Bor at 56.9 degrees geomagnetic latitude, 3.0 degrees farther from the magnetic pole than its map latitude suggests. Sosnovyy Bor sits at 56.9 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 Petrodvorets (40 km), Peterhof (45 km), Kingisepp (64 km). Petrodvorets 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 Sosnovyy Bor has some civil darkness; the shortest month sample still has 1.1 hours.

NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Sosnovyy Bor at 75% across the year, from 59% in May to 91% in December. In the months with at least 4 hours of civil night Sosnovyy Bor averages 77%, against a median of 77% for Glow towns in Russia.
Multiplying civil night by the clear share of the sky gives March the best score, 3.0 hours, ahead of April at 2.7. Sosnovyy Bor's equinox months score 3.0 in March and 2.7 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 Sosnovyy Bor, on 10% of days. At Sosnovyy Bor's level the share runs from 5% in December to 14% in September, while storm days with Kp 5 or more made up 10%.
