How far ahead can the northern lights be forecast?
- Minutes to an hour: satellites 1.5 million km away measure the solar wind before it reaches Earth. This is the surest warning — the “Right now” box uses it.
- 1–3 days: when the Sun throws out a cloud of particles, it takes one to three days to arrive. NOAA's 3-hourly forecast covers these nights; the timing can still be off by a few hours.
- 4–27 days: the Sun turns once every 27 days, and regions that disturbed Earth's field last time often do it again. NOAA's 27-day outlook gives this rough trend — new eruptions are not in it yet.

The Kp scale in plain words
Kp is a 0–9 score for how strongly the Earth's magnetic field is being shaken by the solar wind. The higher it goes, the further from the poles the northern lights reach. Kp 0–2 is a quiet night; Kp 5 and above is a geomagnetic storm.
- Kp 0–2 Quiet Only under the auroral oval: northern Norway, Swedish and Finnish Lapland, Iceland, Alaska, northern Canada.
- Kp 3 Unsettled next 24 h Bright in the Arctic; low on the horizon in central Scandinavia and southern Iceland.
- Kp 4 Active Overhead in the Arctic; low in the north from southern Norway, Sweden, Finland and northern Scotland.
- Kp 5 Minor storm (G1) Scotland, southern Scandinavia, the Baltic states, the northern US states and southern Canada.
- Kp 6 Moderate storm (G2) Northern England, Denmark, northern Germany and Poland, the US Midwest — often clearer in photos than to the eye.
- Kp 7 Strong storm (G3) camera in Kobylisy Most of the UK, the Netherlands, Germany, Poland, Czechia; red glow in photos from France and the northern Alps.
- Kp 8 Severe storm (G4) eye in Kobylisy Central Europe to the eye; red sky in photos from northern Italy, Spain, the Balkans and Turkey's Black Sea coast.
- Kp 9 Extreme storm (G5) Seen across Europe and the US; in photos as far south as the Mediterranean, Turkey and North Africa (May 2024).

Questions and answers
What Kp do you need to see the aurora in Kobylisy?
Only severe geomagnetic storms (Kp 8.3 or more) bring the aurora into view from Kobylisy — a few nights per solar cycle, low in the north.
Which way should I look for the aurora in Kobylisy?
Face north (about 0° from true north). At Kp 8.3 the lower edge of the aurora sits roughly 19° above the horizon; stronger activity lifts it higher and further across the sky.
When is the aurora season in Kobylisy?
Kobylisy gets dark enough for the aurora all year round, though the long winter nights give the most hours to watch.
Is there much light pollution in Kobylisy?
City lights hide all but the brightest displays. Plan to leave the urban area.
When was the aurora last possible in Kobylisy?
The most recent night in our data when activity reached the level Kobylisy needs, during darkness, was 19 January 2026 (Kp 8.7). It has happened on 19 nights since 1995.
