Sun, Solar Storm | featured news

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.

Warming up on its solar cycle, the sun uncorked a a strong solar storm that reached Earth on Monday, federal scientists said, posing a threat to satellites and radio communications, although no interruptions had been reported to date.

The sun unleashed another major solar flare Wednesday, a solar storm so powerful it could spawn dazzling northern lights displays that could be visible from even New York City. The solar flare erupted at 6:23 p.m. EST (2323 GMT), letting loose a wave of charged particles that is aimed straight at Earth and should arrive in the next few days.
