Can you see the northern lights in Guymon?
Only severe geomagnetic storms (Kp 8.3 or more) bring the aurora into view from Guymon — a few nights per solar cycle, low in the north. Since 1995 that level (Kp 8.3) was reached during darkness here on 16 nights.

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.

Cloud layers and weather
Low cloud blocks the aurora completely. Thin high cloud often still lets a bright aurora shine through, so a sky with only high cloud is worth a look.

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 Bright in the Arctic; low on the horizon in central Scandinavia and southern Iceland.
- Kp 4 Active next 24 h 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 Guymon 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 Guymon 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).
Light pollution
Bright suburban sky. Strong sky glow washes out faint aurora. Head out of town for anything but a bright display.

Questions and answers
What Kp do you need to see the aurora in Guymon?
Only severe geomagnetic storms (Kp 8.3 or more) bring the aurora into view from Guymon — a few nights per solar cycle, low in the north.
Which way should I look for the aurora in Guymon?
Face north (about 8° from true north). At Kp 8.3 the lower edge of the aurora sits roughly 15° above the horizon; stronger activity lifts it higher and further across the sky.
When is the aurora season in Guymon?
Guymon 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 Guymon?
Strong sky glow washes out faint aurora. Head out of town for anything but a bright display.
When was the aurora last possible in Guymon?
The most recent night in our data when activity reached the level Guymon needs, during darkness, was 11 November 2025 (Kp 8.7). It has happened on 16 nights since 1995.
