Can you see the northern lights in Bayside?
From Bayside the aurora is seen only during geomagnetic storms (about Kp 6 or more), usually as a glow low in the north. Cameras often pick it up before the eye does. Since 1995 that level (Kp 6) was reached during darkness here on 230 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.

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 camera in Bayside 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) eye in Bayside Northern England, Denmark, northern Germany and Poland, the US Midwest — often clearer in photos than to the eye.
- Kp 7 Strong storm (G3) Most of the UK, the Netherlands, Germany, Poland, Czechia; red glow in photos from France and the northern Alps.
- Kp 8 Severe storm (G4) 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
Suburban sky. Noticeable sky glow. Bright displays are visible, but driving out of town makes a clear difference.
Estimate from NASA VIIRS night-light data (sky-glow model within 50 km). Check access and private land before you go.
Hills and mountains
The horizon towards the north is open (terrain below 0.2°), so low aurora is not blocked.
From elevation data (AWS Terrain Tiles) along seven lines of sight up to 30 km.

Questions and answers
What Kp do you need to see the aurora in Bayside?
From Bayside the aurora is seen only during geomagnetic storms (about Kp 6 or more), usually as a glow low in the north. Cameras often pick it up before the eye does.
Which way should I look for the aurora in Bayside?
Face north (about 354° from true north). At Kp 6 the lower edge of the aurora sits roughly 10° above the horizon; stronger activity lifts it higher and further across the sky.
What is the best month to see the aurora in Bayside?
Over 2005–2025, March gave the best odds in Bayside (1% of nights dark, active enough and mostly clear), followed by May (1%).
When is the aurora season in Bayside?
Bayside 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 Bayside?
Noticeable sky glow. Bright displays are visible, but driving out of town makes a clear difference.
When was the aurora last possible in Bayside?
The most recent night in our data when activity reached the level Bayside needs, during darkness, was 10 October 2026 (Kp 7.0). It has happened on 230 nights since 1995.
