Nick Harkaway just turned this up on Twitter: hfradiospacewx. It’s "Space Weather and Radio Propagation Information," as provided by these people, who apparently could use a dollar or two through Paypal to keep going.
It’s complete gibberish to the untrained eye:
Warning (1591): Geomagnetic K-index of 4 expected… Solar Wind: 519 km/s @ 3.0 protons/cm3… Flares: 6h hi (none) 24h hi (none) …No space weather storms are expected for the next 24 hours…
It is, in fact, The Shipping Forecast for space.
How brilliant is that? All it needs is an equivalent for "Sailing By" to precede it. Maybe a bit of Eno.
