Geomagnetic storms, radio blackouts and GNSS degradation — one federal source, one authoritative scale, no station network.
Authoritative sources exist and publish continuously. Adapter not built.
Planetary geomagnetic disturbance level for an interval.
Particle flux level on the published scale.
HF propagation degradation level.
Published degradation conditions for navigation and timing.
Modelled ground-level induction conditions.
An instrument read a value at a place and a time.
An analyst or a model produced this from other data. It is a product, not a sensor.
A planetary condition. It applies everywhere at once; distance is not a meaningful disclosure.
Published by an authoritative operator of the instrument.
An authoritative body's analytical product. Its uncertainty is the source's own.
No datum problem and no station network, because the measurement is planetary rather than local. The disclosure that replaces nearest-station distance is the interval the index covers — a three-hour Kp does not tell you what happened in a particular ten minutes.
Not named here yet. Candidate sources for this lane exist and are identified internally, but they have not been verified against the primary documentation — and an unverified source attribution on a public page is the exact mistake this company exists to avoid. They appear here when they have been checked, not before.
A precision-agriculture GPS outage during planting. Pipeline or transformer damage from induced currents. An aviation polar-route diversion. A timing failure in a port or a data centre.
That framing is our analysis of where disputes arise, not a claim of fact about any matter.
We are not capturing this lane today, so there is nothing here to sell you and we are not going to pretend otherwise. What we do want is to know what you would actually ask it. Requests decide what gets built next — that is not a courtesy, it is how the order is set.
