Storm level needed
Svetogorsk sits at 61.11N 28.86E in Leningradskaya Oblast', Russia. The IGRF-14 centered dipole puts Svetogorsk at 58.1 degrees geomagnetic latitude, 3.0 degrees farther from the magnetic pole than its map latitude suggests. Svetogorsk sits at 58.1 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 Imatra (9 km), Lappeenranta (37 km), Vyborg (45 km). Imatra sits 0.1 degrees higher 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
From June 4 to July 7 the sun never reaches -6 degrees, so 34 nights in 2026 have no civil darkness at all. SWPC puts it plainly: "It must also be dark so during the summer months at auroral latitudes, the midnight sun prevents auroral observations." Glow's dark season, at least 4 hours of civil night between 18:00 and 06:00, runs from July 28 to May 14 across New Year, 291 days in 2026. Svetogorsk's longest night of the year, Dec 19, has 16 h 17 min of civil night.
Solar midnight at Svetogorsk, when the sun is lowest, falls at 01:00 on local clocks on December 15 and 01:05 on June 15. That is 1 h after midnight in December and 1 h 5 min after midnight in June, the gap set by daylight saving and the equation of time. So at Svetogorsk the darkest hour sits late in SWPC's 10 PM to 2 AM window.

By the 15th-of-the-month sample, December is the darkest month at Svetogorsk with 16.2 hours of civil night and June the lightest at 0.0. Across the year Svetogorsk gets 3,391 hours of civil night. Astronomical night at Svetogorsk, the sun 18 degrees or more below the horizon, lasts 12.5 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Svetogorsk at 76% across the year, from 69% in August to 87% in November. In the months with at least 4 hours of civil night Svetogorsk averages 78%, against a median of 77% for Glow towns in Russia.
Multiplying civil night by the clear share of the sky gives January the best score, 3.3 hours, ahead of March at 2.8. Svetogorsk's equinox months score 2.8 in March and 2.8 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 Svetogorsk, on 24% of days. At Svetogorsk'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 2, the new moon falls on Oct 10 and the full moon on Oct 26, in Europe/Moscow dates. 15 of the 30 nights at Svetogorsk have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 6 has the most at 4 h. Tonight Svetogorsk has 11 h 8 min of civil night, 9 min of it with the moon down.

Questions
- Can you see the northern lights in Svetogorsk?
- Svetogorsk sits at 58.1 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. Clear, dark sky over Svetogorsk still decides it.
- When is it dark enough in Svetogorsk?
- Civil night, the sun at -6 degrees or lower, is missing from Jun 4 to Jul 7. Tonight has 11 h 8 min of it.
- What is the best month for aurora in Svetogorsk?
- January, by civil night at Svetogorsk times the clear share of the sky from NASA POWER's 2001 to 2020 average.
- How cloudy is Svetogorsk in the dark months?
- About 78% mean cloud amount over Svetogorsk in the months with at least 4 hours of civil night, from NASA POWER's 2001 to 2020 all-hours climatology.
- How often is activity high enough for Svetogorsk?
- A 3-hour Kp of 4 or more, the level that puts the average oval edge overhead, occurred on 24% of days from 1996 to 2025 in the GFZ Potsdam record.
- Why does this page point to Imatra?
- Svetogorsk sits within 15 km of Imatra with the same rounded dipole latitude, Kp and dark season, so Glow treats Imatra as the main page for both.
