OUR STAR. YOUR SIGNAL.
A restless Sun.
A connected
world.
Space weather, brought down to Earth.
Follow the energy. Understand the impact.
See the invisible, in a different dimension.
SOL / G2V
Our nearest starYou are exploring an illustrative scenario. These are not current space weather measurements.
01 / SOLAR ACTIVITY
It starts with
a spark.
A change on the Sun can travel far.
Track observed X-ray flux and follow
the conditions shaping our near-space environment.
The pulse of our star.
M2.4
Highest flux in this series
This chart shows observed flux. A peak is not automatically a verified flare event, or a prediction of what happens next.
Explore the NOAA measurement ↗Arrival forecasts.
Enlil arrivals come from NASA DONKI. If that model has not run, a cone that includes Earth gets a Sun-to-Earth transit time. Neither is an operational warning.
X-rays arrive quickly. Solar wind and plasma follow a different journey.
A flare alone does not confirm an Earth-directed coronal mass ejection.
02 / THE AURORAL OVAL
When the sky
comes alive.
Follow the interaction between solar wind
and Earth's magnetic environment.
Some of that energy becomes light.
3D aurora is a schematic illustration.
The location readout uses the model grid.
Model intensity is not your probability of seeing an aurora. Darkness, local weather and the horizon matter.
03 / ORBITAL AWARENESS
A fragile orbit.
A clearer picture.
The systems we depend on
live in an environment that changes.
Keep that context in view.
Illustrative orbital paths.
LEO drag is estimated from Kp and Bz.
No live spacecraft positions.
Low Earth orbit
160–2,000 kmQualitative context from planetary Kp. The LEO table below is a separate schematic drag estimate.
Not for spacecraft operations. LEO figures are a schematic thermosphere, not NRLMSISE-00 and not a lifetime or conjunction product. Radiation and charging need other measurements.
04 / STAY ONE SIGNAL AHEAD
Less noise.
More awareness.
Signal log
SAMPLE BULLETINSample: G1 geomagnetic storm
Planetary Kp 5.33 maps to NOAA G1 (Minor). This is the Kp scale, not a separate issued warning.
Sample: G1 geomagnetic storm scenario
Illustrative bulletin for exploring the dashboard. This is not an issued NOAA alert.
A little perspective
goes a long way.
HELIOS connects the Sun, our planet and the infrastructure above it. Explore the observations. Check their timestamps. Stay curious.
