STATION HELIOS-01 · L1 HALO ORBIT · 1.5 × 10⁶ KM SUNWARD
HELIOS renders the Sun's weather as it arrives — granulation, flares, wind — from a halo orbit upstream of Earth. What you see left the photosphere five seconds ago.
Effective photospheric temperature vs. modelled core temperature. The corona, unexplained, runs a thousand times hotter than the surface beneath it.

Images the corona at 17.1 nm every 12 seconds. The seething disc above is its feed — granulation cells the size of France, resolved and rendered.
Maps the photospheric magnetic field to a tenth of a gauss. When field lines shear and tangle, LODESTONE flags the region — hours before it snaps into a flare.
Holds an artificial eclipse in permanent totality. With the disc blotted out, it watches coronal mass ejections leave the Sun at two thousand kilometres a second.
Counts protons and electrons as the wind blows through it. Sitting upstream at L1, it hands Earth roughly forty minutes of warning before a storm front lands.
Quiet, then unsettled. Background X-ray flux holds in the mid-C range as Region 4172 rotates toward disc centre, keeping a chance of isolated M-class flares through the period.
A recurrent coronal hole stream — CH 1233, the same structure that arrived last rotation — reaches Earth late on day two. Expect wind speeds near 620 km/s and active conditions, Kp 4 to 5, easing as the stream passes.
Aurora, if any, stays pinned to high latitudes. Perth sleeps through this one.
