Best time to see the northern lights in Bobruysk, Belarus

Updated • 21:02 UTC

Bobruysk gets under one clear aurora night a year — 0.1 in a typical year. Only an extreme storm brings the aurora within reach: nights were counted at Kp 8 or higher, which the planetary index last reached on 19 January 2026. April carries the most of that thin history, at 0.03 in a typical year, which is not a month worth booking.

Typical-year figures: a 1996–2026 planetary Kp record crossed with a 2001–2020 cloud normal. They describe a normal year, not tonight — the live Bobruysk forecast shows the actual cloud, moon and darkness right now. Check tonight's forecast for Bobruysk →

June never reaches astronomical darkness at Bobruysk, so no Kp value makes it a viewing month and it is excluded rather than scored.

Opportunity nights are the whole 1996–2026 record. In the current solar cycle alone (since 2023), April has averaged 0 rather than 0.07.

April: 5.3h of astronomical darkness a night
April: 0.07 nights reach the Kp threshold inside that darkness
April: 63.2% mean cloud leaves 0.03 of them clear
April: 57.9% of those nights are moon-free

How these numbers were made

Evaluated at: Bobruysk, 53.1464° N 29.2055° E — darkness and cloud are properties of that point, not of a region.
Darkness: Sun at or below 18° under the horizon (astronomical twilight), sampled every 10 minutes across every year of the Kp record and averaged per night of each month rather than on one representative day.
Geomagnetic record: GFZ Potsdam planetary Kp index, 3-hourly, 1996–2026 — 89,662 intervals, licensed CC BY 4.0.
Cloud: NASA POWER 20-year monthly climatology (2001–2020), parameter CLOUD_AMT. A monthly mean, not a forecast.
Moon: A night counts as moon-free below 35% lunar illumination while the moon is up.
Auroral oval: NOAA auroral-oval model, equatorward boundary near magnetic latitude 67 − 2 × Kp. A model estimate shown beside the measured record; it never replaces it.
Clear opportunity nights: Nights on which at least one 3-hour Kp interval falls inside local astronomical darkness and reaches the count threshold, scaled by one minus the monthly mean cloud amount.
Kp threshold: Nights were counted at Kp 8 or higher, the same threshold the live forecast serves.

Frequently Asked Questions

When can you see the northern lights in Bobruysk?

There is no season for it. Bobruysk averages 0.1 clear aurora nights a year across the 1996–2026 Kp record, so the answer is whenever an extreme storm happens to fall on a dark, clear night. April holds the most of that history, at 0.03 clear nights in a typical year. Watch the live forecast rather than the calendar.

What Kp is needed to see the aurora from Bobruysk?

Bobruysk needs Kp 8 or higher for aurora low on the northern horizon and Kp 9 for a noticeable or bright display. The NOAA auroral-oval model puts the edge of the oval about 54.1° above the northern horizon at Bobruysk at Kp 8. That is a model estimate, separate from the measured Kp record.

Has the aurora ever been visible from Bobruysk?

Yes. In the 1996–2026 planetary Kp record the index reached Kp 8, the threshold these nights were counted at for Bobruysk, most recently on 19 January 2026. The Kp 9 needed for a noticeable display was last reached on 30 October 2003. Whether anyone saw it also depended on the cloud, moonlight and darkness of that night, which the Kp record does not carry.
