Will you see the northern lights tonight?The Sun already knows. Now you can too.

See the Sun now

The Sun's weather, read live — aurora odds tonight, solar storms building, the whole star breathing in real time.

The question worth asking tonight

Somewhere over the pole, the sky is on fire. The only question is how far south it reaches.

The aurora isn't magic — it's the solar wind slamming into Earth's magnetic field and lighting the upper air like a neon sign. When the Sun throws a storm our way, that curtain of green and violet slides down out of the Arctic. Some nights it stops at Alaska. Some nights it reaches Colorado, Scotland, the top of a field you could drive to.

Most people miss it because nobody told them to look up. We tell you — before it happens, for exactly where you stand.

Read live, right now

This is the Sun's weather this minute.

Everything here reads the live state of the star — the solar wind speed, the flares breaking off the surface, the geomagnetic Kp index that decides how far the aurora falls. It's not a forecast someone typed yesterday. It's the Sun as it is, right now, straight from the instruments watching it.

Kp —reading the Sun…
Everything the Sun is doing

Not one number. The whole star, watched.

Aurora tonight

Odds for your latitude, before it happens.

The Kp index

How hard the field is being pushed, live.

Solar flares

The bursts breaking off the surface, ranked.

Solar wind

The stream of particles racing toward us.

Storm warnings

When a G-class storm is inbound, you'll know.

Deep reports

What it means, in plain language, daily.

Where the numbers come from
The Kp index

A 0–9 scale of how disturbed Earth's magnetic field is. Below 3, the aurora hugs the pole. At 5 or more, it's a geomagnetic storm — and the lights come south.

Solar wind

A million-mile-an-hour stream of charged particles off the Sun. When a fast gust hits our field, the sky answers within hours.

Real instruments

Kp, flare class, and wind speed come straight from NOAA's Space Weather Prediction Center and NASA — the same feeds the scientists watch.
