At about 5:45 a.m. Eastern time Thursday, the geomagnetic storm from a massive solar flare that rippled the surface of the sun on Tuesday night finally reached the Earth's atmosphere. The Facebook page for the National Oceanic and Atmospheric Administration NWS Space Weather Prediction Center made the announcement. But so far, the storm has been a bit of a dud.

An impressive solar flare is heading toward Earth and could disrupt power grids, GPS and airplane flights....

Fast on the heels of a solar storm that delivered a glancing blow over the weekend — triggering bright auroras in Canada and Scandinavia — the sun released an even more energetic blast of radiation and charged plasma overnight that could disrupt GPS signals and the electrical grid Tuesday, especially at high latitudes, space weather experts warned Monday morning.

A huge sunspot unleashed a blob of charged plasma Thursday that space weather watchers predict will blast past the Earth on Sunday. Satellite operators and power companies are keeping a close eye on the incoming cloud, which could distort the Earth’s magnetic field and disrupt radio communications, especially at higher latitudes.

Larger than expected variations in the Sun's ultraviolet output can explain weather patterns in recent northern hemisphere winters, including the UK's cold spells, scientists conclude.

The calmest sun in a century may rustle up more hurricanes in the season that officially began Tuesday.
