PLANETARY KP INDEX ?

Kp Index · Geomagnetic Activity
A 0–9 scale measuring how disturbed Earth's magnetic field is. Higher values mean a stronger geomagnetic storm and the aurora oval expanding further from the poles — Jersey typically needs Kp 7+ to have any chance.

IMF Bz · North-South Field Direction
The north-south direction of the Sun's magnetic field carried by the solar wind. When it points south (negative) it can connect with Earth's own field, letting energy flood in and power the aurora. North (positive) does the opposite.

Solar Wind Speed
How fast the stream of charged particles from the Sun is travelling. Typical speeds sit around 300–450 km/s; faster streams (often from coronal holes or CMEs) hit Earth's field harder and can trigger stronger geomagnetic activity.

Solar Wind Density
How tightly packed the solar wind's particles are. A sudden jump in density — especially combined with a southward Bz — often signals a CME impact and can help trigger or intensify a geomagnetic storm.

AURORA OVAL · JERSEY

VISIBILITY CHECK

The aurora forms an oval-shaped ring around the magnetic pole. As geomagnetic activity (Kp) rises, that ring expands further from the pole and can push south enough to reach Jersey's latitude — 49.18°N. Because Jersey sits much further south than typical aurora-viewing latitudes, this only happens during severe-to-extreme geomagnetic storms (Kp 7–9). The estimate below is a rough guide based on Kp, not a precise real-time position.

You are looking down on the North Pole, turned so Jersey sits at the bottom. The glowing band is where aurora is likely right now; the dashed ring is Jersey's latitude. To see aurora from the island, the glow needs to reach — or come close to — that ring on the bottom of the picture, because you would be looking north, up the dashed line towards the pole. The real oval is not a neat circle: it bulges further south on the night side.

LIVE SOLAR IMAGERY

NASA/ESA SOHO & SDO

Near real-time views of the Sun itself, straight from NASA/ESA's SOHO and SDO spacecraft. Each instrument looks at something different — sunspots, magnetic field, different layers of the corona, or eruptions heading out into space. Tap a tile below to switch the view. Tap and hold or hover over a button for a description of the image.

BEST VANTAGE POINTS

JERSEY

Aurora appears low on the northern horizon, so the best spots are elevated, north-facing, and away from light pollution. These north-coast headlands give the clearest, darkest sightlines out over the sea — tap a marker for details.

GROSNEZ POINT
Jersey's northwest tip — wide open sea horizon, minimal light pollution, elevated castle ruins headland.
PLEMONT POINT
High north-coast headland with an unobstructed view out to sea, well away from St Helier's glow.
SOREL POINT
The highest point on the island's north coast — a popular local stargazing spot for a reason.
BONNE NUIT / RONEZ
Elevated headland with a clear north-facing sea view and dark surroundings.
BOULEY BAY
Steep north-coast bay with an open horizon; the viewpoint car park at the top gives good elevation.

SKY CONDITIONS OVER JERSEY

CLOUD COVER

All the geomagnetic activity in the world won't help if the sky is overcast — check cloud cover here before heading out. Look for clear or mostly-clear skies, especially to the north, over the viewing window.
