A strong solar storm should hit the Earth, scientists have warned. Precautions have been taken, aircraft had to change their routes, but then shone only some auroras.

The forecasts space weather this week read a worrying: the "biological risk" for astronauts by high-energy solar radiation might be increased, warned the U.S. weather agency NOAA on Tuesday. Also passengers in airplanes on polar routes threatened to be exposed to increased radiation, NOAA added on Wednesday.

Satellite systems could be "significant boost" power grids be affected at high latitudes of minor fluctuations, GPS navigation and radio reception may be disturbed. A positive prediction, there were also: From Alaska to Scandinavia are expected to spread auroras.

What really happened, let astonished experts: Apart from occasional northern lights, the solar storm had virtually no consequences. "Are you also disappointed to have not seen a Polar Lights?"
